RecordBytesSent() does not require cs_vSend to be locked, so reduce the scope of cs_vSend.

0000a0c7e9e4e7c1afafe6ef75b7624f4c573190 Remove confusing and almost useless "unexpected version" warning (MarcoFalke)
Pull request description:
It is useless because it isn't displayed for most users:
* It isn't displayed in normal operation (because the validation debug category is disabled by default)
* It isn't displayed for users that sync up their nodes intermittently, e.g. once a day or once a week (because it is disabled for IBD)
* It is only displayed in the debug log (as opposed to the versionbits warning, which is displayed more prominently)
It is confusing because it doesn't have a use case:
Despite the above, if a user *did* see the warning, it would most likely be a false positive (like it has been in the past). Even if it wasn't, there is nothing they can do about it. The only thing they could do is to check for updates and hope that a fixed version is available. But why would the user be so scrupulously precise in enabling the warning and reading the log, but then fail to regularly check update channels for updated software?

The first commit improves documentation on setup_clean_chain which is misunderstood quite frequently. Most importantly it fixes the TestShell docs which are simply incorrect.
The second commit removes the instances of `setup_clean_clain` in functional tests where it is not changing the default.
This used to be part of #19168 which also sought to rename`setup_clean_chain`.

6f2c4fd0775a9c45eacc4bab8f138528852fdf44 netinfo: add user help documentation (Jon Atack)
Pull request description:
This is the help doc commit of #20764 without the rest of the PR or anything new since the 0.21.0 branch-off in order to target giving users a -netinfo help doc for 0.21.
- to test the new help
```
$ ./src/bitcoin-cli -netinfo help
```
- to see the updated short help
```
$ ./src/bitcoin-cli -help | grep -A4 netinfo
```
<details><summary><code>-netinfo</code> help doc</summary><p>
```
$ ./src/bitcoin-cli -netinfo help
-netinfo level "help"
Returns a network peer connections dashboard with information from the remote server.
Under the hood, -netinfo fetches the data by calling getpeerinfo and getnetworkinfo.
An optional integer argument from 0 to 4 can be passed for different peers listings.
Pass "help" to see this detailed help documentation.
If more than one argument is passed, only the first one is read and parsed.
Suggestion: use with the Linux watch(1) command for a live dashboard; see example below.
Arguments:
1. level (integer 0-4, optional) Specify the info level of the peers dashboard (default 0):
0 - Connection counts and local addresses
1 - Like 0 but with a peers listing (without address or version columns)
2 - Like 1 but with an address column
3 - Like 1 but with a version column
4 - Like 1 but with both address and version columns
2. help (string "help", optional) Print this help documentation instead of the dashboard.
Result:
* The peers listing in levels 1-4 displays all of the peers sorted by direction and minimum ping time:
Column Description
------ -----------
<-> Direction
"in" - inbound connections are those initiated by the peer
"out" - outbound connections are those initiated by us
type Type of peer connection
"full" - full relay, the default
"block" - block relay; like full relay but does not relay transactions or addresses
net Network the peer connected through ("ipv4", "ipv6", "onion", "i2p", or "cjdns")
mping Minimum observed ping time, in milliseconds (ms)
ping Last observed ping time, in milliseconds (ms)
send Time since last message sent to the peer, in seconds
recv Time since last message received from the peer, in seconds
txn Time since last novel transaction received from the peer and accepted into our mempool, in minutes
blk Time since last novel block passing initial validity checks received from the peer, in minutes
age Duration of connection to the peer, in minutes
asmap Mapped AS (Autonomous System) number in the BGP route to the peer, used for diversifying
peer selection (only displayed if the -asmap config option is set)
id Peer index, in increasing order of peer connections since node startup
address IP address and port of the peer
version Peer version and subversion concatenated, e.g. "70016/Satoshi:21.0.0/"
* The connection counts table displays the number of peers by direction, network, and the totals
for each, as well as a column for block relay peers.
* The local addresses table lists each local address broadcast by the node, the port, and the score.
Examples:
Connection counts and local addresses only

8f073076b102b77897e5a025ae555baae3d1f671 wallet: Increase OUTPUT_GROUP_MAX_ENTRIES to 100 (Fabian Jahr)
Pull request description:
Follow-up to #17824.
This increases OUTPUT_GROUP_MAX_ENTRIES to 100 which means that OutputGroups will now be up to 100 outputs large, up from previously 10. The main motivation for this change is that during the PR review club on #17824 [several participants signaled](https://bitcoincore.reviews/17824.html#l-339) that 100 might be a better value here.
I think fees should be manageable for users but more importantly, users should know what they can expect when using the wallet with this configuration, so I also tried to clarify the documentation on `-avoidpartialspends` and `avoid_reuse` a bit. If there are other additional ways how or docs where users can be made aware of the potential consequences of using these parameters, please let me know. Another small upside is that [there seem to be a high number of batching transactions with 100 and 200 inputs](https://miro.medium.com/max/3628/1*sZ5eaBSbsJsHx-J9iztq2g.png)([source](https://medium.com/@hasufly/an-analysis-of-batching-in-bitcoin-9bdf81a394e0)) giving these transactions a bit of a larger anonymity set, although that is probably a very weak argument.

8c09c0c1d18885ef94f79b3f2d073f43269bc95d fuzz: Avoid time-based "non-determinism" in fuzzing harnesses by using mocked GetTime() (practicalswift)
Pull request description:
Avoid time-based "non-determinism" in fuzzing harnesses by using mocked `GetTime()`.
Prior to this commit the fuzzing harnesses `banman`, `connman`, `net` and `rbf` had time-based "non-determinism". `addrman` is fixed in #20425. `process_message` and `process_messages` are left to fix: simply using mock time is not enough for them due to interaction with `IsInitialBlockDownload()`.
See [`doc/fuzzing.md`](https://github.com/bitcoin/bitcoin/blob/master/doc/fuzzing.md) for information on how to fuzz Bitcoin Core. Don't forget to contribute any coverage increasing inputs you find to the [Bitcoin Core fuzzing corpus repo](https://github.com/bitcoin-core/qa-assets).
Happy fuzzing :)

This should also enable the check for MSVC. From my reading of https://docs.microsoft.com/en-us/cpp/build/reference/zc-cplusplus?view=msvc-160 and https://devblogs.microsoft.com/cppblog/msvc-now-correctly-reports-__cplusplus/ if we set the `/Zc:__cplusplus` switch in additional options, MSVC will report the correct value for `__cplusplus`. However I have not tested this.

77772a1b809e443a6861ee49009ff8bc55cff9c3 doc: Rework internal and external links (MarcoFalke)
Pull request description:
Some minor changes:
* Move Bitcoin Core download link to the very top. *Reason:* The download link has nothing to do with the section that explains Bitcoin. Also, anyone quickly looking for the download link will find it faster.
* Add a new link to the doc folder. *Reason*: Apart from the documentation that is shipped with the binary software, the doc folder is the primary location for Bitcoin Core related documentation.
* Remove dead link to pdf. *Reason*: The pdf can be trivially found by asking a search engine.
* Remove reference to "build server". *Reason*: There is no "build server". The CI system is explained in the next sentence in detail.
* Remove dead? link to translation mailing list. *Reason*: The translation process is explained in `doc/translation_process.md`, no need to explain it in detail in the main readme.

## Issue being fixed or feature implemented
Unlike bitcoin we are using PREVIOUS block in `GetBlockSubsidy()`.
That creates special case for genesis block, because it doesn't have
previous block. In this special case instead of calling
`GetBlockSubsidy` should be used pre-calculated value. To avoid
confusion for new code and simplify implementation, there's introduced a
new method `GetBlockSubsidyPrev` that has other interface: it takes
pointer `CBlockIndex* prev` in agruments instead pair of height + nbits.
These changes are follow-up for #5501
## What was done?
Implemented new method `GetBlockSubsidyPrev()` and used instead of
`GetBlockSubsidy` when it is more convenient.
## How Has This Been Tested?
Run unit/functional tests.

## Issue being fixed or feature implemented
Make CI builds faster.
We have this
https://github.com/dashpay/dash/blob/develop/ci/dash/build_src.sh#L18
but by that time `CCACHE_SIZE` is set to 100M via
https://github.com/dashpay/dash/blob/develop/ci/test/00_setup_env.sh#L51
already.
## What was done?
set `CCACHE_SIZE` variable in `.gitlab-ci.yml`, drop confusing and
useless lines from `ci/dash/build_src.sh` (`CCACHE_SIZE` and
`CCACHE_COMPRESS` defaults are handled by `ci/test/00_setup_env.sh`)
## How Has This Been Tested?
I set `CCACHE_SIZE` to 400M yesterday via Gitlab UI to test it.
results:
before, trivial doc change, 100M:
https://gitlab.com/dashpay/dash/-/jobs/4931233566#L59 (~17 minutes)
after, trivial code change, 400M:
https://gitlab.com/dashpay/dash/-/jobs/4935764148#L80 (~12 minutes)
Removed it from Gitlab UI now but it should still say `Set cache size
limit to 400.0 MB` in logs for this PR.

c7437185589926ec8def2af6bede6a407b3d2e4a test: add further BIP37 size limit checks to p2p_filter.py (Sebastian Falbesoner)
Pull request description:
This is a follow-up PR to #18628. In addition to the hash-functions limit test introduced with commit fa4c29bc1d, it adds checks for the following size limits as defined in [BIP37](https://github.com/bitcoin/bips/blob/master/bip-0037.mediawiki):
ad message type `filterload`:
> The filter itself is simply a bit field of arbitrary byte-aligned size. The maximum size is **36,000 bytes**.
ad message type `filteradd`:
> The data field must be smaller than or equal to **520 bytes** in size (the maximum size of any potentially matched object).
Also introduces new constants for the limits (or reuses the max script size constant in case for the `filteradd` limit).
Also fixes#18711 by changing the misbehaviour check on "filteradd without filterset" (introduced with #18544) below to also use the more commonly used `assert_debug_log` method.

5eae034996b340c19cebab9efb6c89d20fe051ef net: limit BIP37 filter lifespan (active between 'filterload' and 'filterclear') (Sebastian Falbesoner)
Pull request description:
This PR fixes https://github.com/bitcoin/bitcoin/issues/18483. On the master branch, there is currently _always_ a BIP37 filter set for every peer: if not a specific filter is set through a `filterload` message, a default match-everything filter is instanciated and pointed to via the `CBloomFilter` default constructor; that happens both initially, when the containing structure `TxRelay` is constructed:
c0b389b335/src/net.h (L812)
and after a loaded filter is removed again through a `filterclear` message:
c0b389b335/src/net_processing.cpp (L3201)
The behaviour was introduced by commit 37c6389c5a (an intentional covert fix for [CVE-2013-5700](https://github.com/bitcoin/bitcoin/pull/18515), according to gmaxwell).
This default match-everything filter leads to some unintended side-effects:
1. `getdata` request for filtered blocks (i.e. type `MSG_FILTERED_BLOCK`) are always responded to with `merkleblock`s, even if no filter was set by the peer, see issue #18483 (strictly speaking, this is a violation of BIP37) c0b389b335/src/net_processing.cpp (L1504-L1507)
2. if a peer sends a `filteradd` message without having loaded a filter via `filterload` before, the intended increasing of the banscore never happens (triggered if `bad` is set to true, a few lines below) c0b389b335/src/net_processing.cpp (L3182-L3186)
This PR basically activates the `else`-branch code paths for all checks of `pfilter` again (on the master branch, they are dead code) by limiting the pointer's lifespan: instead of always having a filter set, the `pfilter` is only pointing to a `CBloomFilter`-instance after receiving a `filterload` message and the instance is destroyed again (and the pointer nullified) after receiving a `filterclear` message.
Here is a before/after comparison in behaviour:
| code part / scenario | master branch | PR branch |
| --------------------------------------------- | ---------------------------------- | ---------------------------------------------------- |
| `getdata` processing for `MSG_FILTERED_BLOCK` | always responds with `merkleblock` | only responds if filter was set via `filterload` |
| `filteradd` processing, no filter was loaded | nothing | peer's banscore increases by 100 (i.e. disconnect) |
On the other code parts where `pfilter` is checked there is no change in the logic behaviour (except that `CBloomFilter::IsRelevantAndUpdate()` is unnecessarily called and immediately returned in the master branch).
Note that the default constructor of `CBloomFilter` is only used for deserializing the received `filterload` message and nowhere else. The PR also contains a functional test checking that sending `getdata` for filtered blocks is ignored by the node if no bloom filter is set.
