Pull request description:
## Additional Information
* Depends on https://github.com/dashpay/dash/pull/5966
* `CTxMemPool`'s ProTx logic took the presence of `CDeterministicMNManager` for granted. To account for `CTxMemPool` instances that aren't seeded with the pointer to the manager (usually because the unit test doesn't call for them), refactoring was done to make ProTx code paths conditional on the manager pointer being set to something.
* Setting the manager pointer is done through `CTxMemPool::Init()`, to avoid having to pass another `std::unique_ptr` const-ref and also because `CTxMemPool` can _technically_ work without the manager if ProTx logic is not needed (and `CTxMemPool::existsProviderTxConflict()` isn't called)
* `CTxMemPool::Init()` doesn't allow overwriting a not-`nullptr` manager pointer. If that is desired, then `CTxMemPool::Reset()` should be called first. This was done to avoid unintentional double-initialization/overwriting.
## Breaking Changes
None. Changes are limited to refactoring.

Pull request description:
While looking at issue #21351, it turned out that the problem was a lack of tor v3 addresses known to the node. It became clear (e.g. https://github.com/bitcoin/bitcoin/issues/21351#issuecomment-811004779) that a CLI command returning the number of addresses the node knows per network (with a tor v2 / v3 breakdown) would be very helpful. This patch adds that.
`-addrinfo` is useful to see if your node knows enough addresses in a network to use options like `-onlynet=<network>`, or to upgrade to the upcoming tor release that no longer supports tor v2, for which you'll need to be sure your node knows enough tor v3 peers.
```
$ bitcoin-cli --help | grep -A1 addrinfo
-addrinfo
Get the number of addresses known to the node, per network and total.
$ bitcoin-cli -addrinfo
{
"addresses_known": {
"ipv4": 14406,
"ipv6": 2511,
"torv2": 5563,
"torv3": 2842,
"i2p": 8,
"total": 25330
}
}
$ bitcoin-cli -addrinfo 1
error: -addrinfo takes no arguments
```
This can be manually tested, for example, with commands like this:
```
$ bitcoin-cli getnodeaddresses 0 | jq '.[] | (select(.address | contains(".onion")) | select(.address | length <= 22)) | .address' | wc -l
5563
$ bitcoin-cli getnodeaddresses 0 | jq '.[] | (select(.address | contains(".onion")) | select(.address | length > 22)) | .address' | wc -l
2842
$ bitcoin-cli getnodeaddresses 0 | jq '.[] | .address' | wc -l
25330
```

Pull request description:
## Additional Information
* Dependency for https://github.com/dashpay/dash/pull/5982
* Population of `ADDRS` in `p2p_addr`(`v2`)`_relay` in Dash is done in the test object ([source](0a62b9f985/test/functional/p2p_addrv2_relay.py (L42-L49))) as opposed to upstream, where it is done in the global state ([source](d930c7f5b0/test/functional/p2p_addrv2_relay.py (L23-L35))). This is because Dash specifically relies on `self.mocktime` instead of Bitcoin, which will work with simply sampling current time (`time.time()`).
* [bitcoin#22211](https://github.com/bitcoin/bitcoin/pull/22211) adds changes ([source](https://github.com/bitcoin/bitcoin/pull/22211/files#diff-d3d7b1bb23f25a96c9c7444a79159ad1799895565f99efebf1618e41e886bd53R44-R46)) that add usage of `ADDRS` outside the test object. That, alongside with other considerations, resulted in [dash#5967](https://github.com/dashpay/dash/pull/5967) and a discussion ([source](https://github.com/dashpay/dash/pull/5967/files#r1548101561))
* Eventually, following the footsteps of [dash#5967](https://github.com/dashpay/dash/pull/5967), `ADDRS` was defined outside but setup within the test object. This worked just fine ([build](https://gitlab.com/dashpay/dash/-/jobs/6594036014)) but displeased the linter ([build](https://gitlab.com/dashpay/dash/-/jobs/6594035886)) because `ADDRS` type could not be implicitly determined solely on usage in the global scope.
* An attempt to correct this was done by realignment with upstream ([commit](262d00682c)), which pleased the linter ([build](https://gitlab.com/dashpay/dash/-/jobs/6597322521)) but broken the test ([build](https://gitlab.com/dashpay/dash/-/jobs/6597322548)) for the reasons as mentioned above.
* Therefore, to keep the linter happy, `ADDRS` has been annotated as a `List[CAddress]` (which involved importing `List` but that's fine) ([commit](cb6d36df7d))
* Working on [bitcoin#21528](https://github.com/bitcoin/bitcoin/pull/21528) proved challenging due to differences in Dash's and Bitcoin's approach to relaying and the workarounds used to accommodate for that.
* Bitcoin conditionally initializes `m_tx_relay` ([source](3f7250b328/src/net.cpp (L2989-L2991))) and can always check if transaction relaying is permitted by checking if it's initialized ([source](3f7250b328/src/net_processing.cpp (L1820-L1826))).
* Dash unconditionally initializes it ([source](0a62b9f985/src/net.h (L605-L607))). Earlier, Dash used to check if it's _appropriate_ to relay transactions by checking if it can relay addresses ([source](dc6f52ac99/src/net_processing.cpp (L2134-L2140))), which at the time, simply meant, it wasn't a block-only connection ([source](dc6f52ac99/src/net.h (L568-L572))).
* This mutual exclusivity no longer held true in [dash#5964](https://github.com/dashpay/dash/pull/5964) and therefore, some transaction relay decisions were bound to **not** being a block-only connection ([commit](26c39f5b92)) but some were left behind, adopting `RelayAddrsWithPeer()` ([source](0a62b9f985/src/net_processing.cpp (L2215-L2221))), which, to be noted, is determined by the initialization status of `Peer::m_addr_known` ([source](0a62b9f985/src/net_processing.cpp (L839-L842))), which, so far, was pegged to **not** block-relay connection status ([source](0a62b9f985/src/net_processing.cpp (L1319))).
* [bitcoin#21528](https://github.com/bitcoin/bitcoin/pull/21528) got rid of `RelayAddrsWithPeer()` and replaced it with `Peer::m_addr_relay_enabled` ([source](3f7250b328/src/net_processing.cpp (L237-L251))), which is setup using `Peer::SetupAddressRelay()` ([source](3f7250b328/src/net_processing.cpp (L637-L643))). This means, rather than defining the address relay status during construction, it is setup during the first address-related message (i.e. `ADDR`, `ADDRV2`, `GETADDR`) ([source](3f7250b328/src/net_processing.cpp (L227-L236))).
* Meaning, until the first addr-related message happens, the state is has not been determined and defaults to `false`. Because some `m_tx_relay` usage still piggybacked on addr-relay permission to determine tx-relay, if a transaction message is processed before an address message is processed, there will be a false-negative condition.
The transaction relay logic won't run since it's expecting that if transactions can be relayed, so can addresses and checks for address relaying but believes that it cannot do address relaying, borrowing that state for transaction relaying, despite address relaying permissions actually being indeterminate since it hasn't had a chance to validate its eligibility.
* There were two approaches, run `SetupAddressRelay()` as early in the connection as possible to substitute for the "determine at construction" behaviour and change no other conditional statements... and break address-related tests _or_ move the remaining conditional transaction relay logic to use **not** block-only connection checks instead.
* We've gone with the latter, resulting in some changes where the condition only changes form but is the same (`RelayAddrsWithPeer()` > `Peer::m_addr_relay_enabled`) ([source](109c5a9383 (diff-6875de769e90cec84d2e8a9c1b962cdbcda44d870d42e4215827e599e11e90e3L2131-L2134))) but other changes where the condition itself has been changed (`RelayAddrsWithPeer()` > `!CNode::IsBlockOnlyConn()`) ([source](109c5a9383 (diff-6875de769e90cec84d2e8a9c1b962cdbcda44d870d42e4215827e599e11e90e3R2256-R2259)))
* This does mean that in [dash#5982](https://github.com/dashpay/dash/pull/5982), `Peer::m_block_relay_only` is introduced to be the counterpart to `Peer::m_addr_relay_enabled` ([source](45b48dae0a/src/net_processing.cpp (L321-L322))) to account for some `CConnman` logic being moved into `PeerManager` ([source](45b48dae0a/src/net_processing.cpp (L2186-L2195))), which, in a way, reverts [dash#5339](https://github.com/dashpay/dash/pull/5339) but also, doesn't, since it moves the information into `Peer` instead of reinstating it into `CNode`.
* This was eventual since the underlying presumption that `CNode::IsAddrRelayPeer() == !CNode::IsBlockOnlyConn()` no longer holds true (also because `CNode::IsAddrRelayPeer()` doesn't exist anymore).
Special thanks to @UdjinM6 for help with understanding Dash-specifics with respect to functional tests through help on [dash#5964](https://github.com/dashpay/dash/pull/5964) and [dash#5967](https://github.com/dashpay/dash/pull/5967)
## Breaking Changes
None expected.
RPC changes have been introduced in `getnodeaddresses`, where a new input `network`, can filter addresses based on desired network and a new output, also `network`, will associate the address with the origin network. This change is expected to be backwards-compatible.

Despite removeUnchecked not explicitly requiring CDeterministicMNManager,
it has also been made conditional due to addUnchecked requiring the manager
and allowing for some operations but not others when pertaining to a
transaction type could allow inconsistencies to arise. Better to treat as
one unit and skip both if manager isn't present.
In bitcoin#21528, the value of `m_addr_relay_enabled` isn't determined
until the first ADDR/ADDRV2/GETADDR call. Until then, it'll always default
to `false`. This creates a false-negative where a term equivalent to "not
a block connection" no longer reliably means that.
Therefore we need to switch to directly querying "not a block-only
connection".

Notice, that function name is included now by default to logs with `-logfunctionnames` and many logs have function name twice now such as:

For further development need to take it in account and do not use more direct calls `__func__` from code as well as reduce usages in codebase.

Pull request description:
## Additional Information
* Dependency for https://github.com/dashpay/dash/pull/5980
* `CActiveMasternodeManager` construction is moved upwards (_before_ `PeerManager` construction) to avoid having to pass it as a `std::unique_ptr` const-ref. Shouldn't have any effect since _initialization_ is done in `ThreadImport`.
* `CConnman::SetNetworkActive` will require a pointer to `CMasternodeSync` in order to call `CMasternodeSync::Reset()`. As it is no longer available as a global, it will need to be manually called through for the effect to happen as the `CConnman` constructor will simply pass a `nullptr` when calling `SetNetworkActive`, bypassing the `Reset()` call.
`CMasternodeSync` is appropriately passed through in RPC (`setnetworkactive`) and interfaces.
* `CheckSpecialTx` was moved into `CSpecialTxProcessor` to avoid having to expose `CDeterministicMNManager` to `MemPoolAccept` (though it has been exposed to `CChainstateHelper` through a helper, `CChainState::ChainHelper()` that was introduced in this PR).
* As a drawback, some RPC functions that otherwise only needed access to `CDeterministicMNManager`, will also be accessing `CChainstateHelper`.
## Concerns
* ~~Some tests seem to sporadically fail (fail as part of a suite but succeed when run individually, no changes in this PR should worsen resource contention) but attempting to reproduce them reliably hasn't succeeded so far.~~
It appears the sporadic failure is shown in `p2p_node_network_limited.py` during TSan runs (see [failed run](https://gitlab.com/dashpay/dash/-/jobs/6529052189) for commit f95ffa7b70d5d20b6321ff11d37ad52425d446d1 that then succeeded in a [second attempt](https://gitlab.com/dashpay/dash/-/jobs/6530402585) versus a similar [failed run](https://gitlab.com/dashpay/dash/-/jobs/6546952668) for e210cb734e16e0ecef9601251fe0e074ed86827e that also succeeded on [second try](https://gitlab.com/dashpay/dash/-/jobs/6549470339)). Similar behaviour has not been observed on `develop` (as of this writing is 27c0813c08).
## Breaking changes
`CMasternodeSync::Reset()` will not be called on every `CConnman` entity instantiated. Behaviour changes as a result of that are not substantiated. Protocol, networking or interface changes are not expected, changes are primarily refactoring.

Pull request description:
Adds `parent_desc` field to the `getaddressinfo` RPC to export a public descriptor. Using the given address, `getaddressinfo` will look up which `DescriptorScriptPubKeyMan` can be used to produce that address. It will then return the descriptor for that `DescriptorScriptPubKeyMan` in the `parent_desc` field. The descriptor will be in a normalized form where the xpub at the last hardened step is derived so that the descriptor can be imported to other wallets. Tests are added to check that the correct descriptor is being returned for the wallet's addresses and that these descriptors can be imported and used in other wallets.
As part of this PR, a `ToNormalizedString` function is added to the descriptor classes. This really only has an effect on `BIP32PubkeyProvider`s that have hardened derivation steps. Tests are added to check that normalized descriptors are returned.

Pull request description:
This PR fixes tests for when BDB is not compiled. Tests which rely on or test legacy wallet behavior are disabled and skipped when BDB is not compiled. For the components of some tests that are for legacy wallet things, those parts of the tests are skipped.
For the majority of tests, changes are made so that they can be run with either legacy wallets or descriptor wallets without materially effecting the test. Most tests only need the wallet for balance and transactions, so the type of wallet is not an important part of those tests. Additionally, some tests are wallet agnostic and modified to instead use the test framework's MiniWallet.

Pull request description:
This PR adds a `ban_duration` and `time_remaining` field to the `listbanned` RPC command. Thanks to jonatack, this PR also expands the `listbanned` test coverage to include these new fields
It's useful to keep track of `ban_duration` as this is another data point on which to sort banned peers. I found this helpful in adding additional context columns to the GUI `bantablemodel` as part of a follow-up PR. As [suggested](https://github.com/bitcoin/bitcoin/pull/21602#issuecomment-813486134) by jonatack, `time_remaining` is another useful user-centric data point.
Since a ban always expires after its created, the `ban_created` field is now placed before the `banned_until` field. This new ordering is more logical.
This PR also improves the `help listbanned` output by providing additional context to the descriptions of the `address`, `ban_created`, and `banned_until` fields.

With this PR the GUI handles the wallet-related exception, and:
- display it to a user:
- prints a message to `stderr`:
```
************************
EXCEPTION: 18NonFatalCheckError
wallet/wallet.cpp:2677 (IsCurrentForAntiFeeSniping)
Internal bug detected: '!chain.findBlock(block_hash, FoundBlock().time(block_time))'
You may report this issue here: https://github.com/bitcoin/bitcoin/issues
bitcoin in QPushButton->SendCoinsDialog
```
- writes a message to the `debug.log`
- and, if the exception is a non-fatal error, leaves the main window running.

Code review ACK b8e5d0d3fe3386807d47f50d13ac34fcd2a538fd. This is great! I think more improvements are possible but implementation is very clean and I love how targeted each commit is. Changes since last review: adding more explanatory text, making links clickable, reorganizing.

223b1ba7d90509a47ea07af46f4b9c3b8efbc9f8 doc: Use CONFIG_SITE instead of --prefix (Hennadii Stepanov)
Pull request description:
The current examples of `--prefix=...` option usage to point `configure` script to appropriate `depends` directory is not [standard](https://www.gnu.org/prep/standards/html_node/Directory-Variables.html). This causes some [confusion](https://github.com/bitcoin/bitcoin/pull/16691) and a bit of inconvenience.
Consider a CentOS 7 32 bit system. Packages `libdb4-devel`, `libdb4-cxx-devel`, `miniupnpc-devel` and `zeromq-devel` are unavailable from repos. After recommended build with depends:
```
cd depends
make
cd ..
./autogen.sh
./configure --prefix=$PWD/depends/i686-pc-linux-gnu
make
```
a user is unable to `make install` compiled binaries neither locally (to `~/.local`) nor system-wide (to `/usr/local`) as `--prefix` is set already.
Meanwhile, the standard approach with using [`config.site`](https://www.gnu.org/software/automake/manual/html_node/config_002esite.html) files allows both possibilities:
```
cd depends
make
cd ..
./autogen.sh
CONFIG_SITE=$PWD/depends/i686-pc-linux-gnu/share/config.site ./configure --prefix ~/.local
make
make install
```
or
```
CONFIG_SITE=$PWD/depends/i686-pc-linux-gnu/share/config.site ./configure
make
sudo make install # install to /usr/local
```
Moreover, this approach is used in [Gitian descriptors](https://github.com/bitcoin/bitcoin/tree/master/contrib/gitian-descriptors) already.
