## Issue being fixed or feature implemented
Dead-code, useless conditions can be potential source of bug.
## What was done?
See each particular commit.
This particular commit "fix: check ptr in assert before usage" fixes
potential UB - `assert` is better than UB.
All other commits are not fixing any real issue, just to tidy-up code a
bit or to shut a potential warning.
## How Has This Been Tested?
Run unit/functional tests.

105941b726c078642e785ecb7b6834ba814381b0 net: use stronger AddLocal() for our I2P address (Vasil Dimov)
Pull request description:
There are two issues:
### 1. Our I2P address not added to local addresses.
* `externalip=` is used with an IPv4 address (this sets automatically `discover=0`)
* No `discover=1` is used
* `i2psam=` is used
* No `externalip=` is used for our I2P address
* `listenonion=1 torcontrol=` are used
In this case `AddLocal(LOCAL_MANUAL)` [is used](94f83534e4/src/torcontrol.cpp (L354)) for our `.onion` address and `AddLocal(LOCAL_BIND)` [for our](94f83534e4/src/net.cpp (L2247)) `.b32.i2p` address, the latter being [ignored](94f83534e4/src/net.cpp (L232-L233)) due to `discover=0`.
### 2. Our I2P address removed from local addresses even if specified with `externalip=` on I2P proxy restart.
* `externalip=` is used with our I2P address (this sets automatically `discover=0`)
* No `discover=1` is used
* `i2psam=` is used
In this case, initially `externalip=` causes our I2P address to be [added](94f83534e4/src/init.cpp (L1266)) with `AddLocal(LOCAL_MANUAL)` which overrides `discover=0` and works as expected. However, if later the I2P proxy is shut down [we do](94f83534e4/src/net.cpp (L2234)) `RemoveLocal()` in order to stop advertising our I2P address (since we have lost I2P connectivity). When the I2P proxy is started and we reconnect to it, restoring the I2P connectivity, [we do](94f83534e4/src/net.cpp (L2247)) `AddLocal(LOCAL_BIND)` which does nothing due to `discover=0`.
To resolve those two issues, use `AddLocal(LOCAL_MANUAL)` for I2P which is also what we do with Tor.

dde69f20a01acca64ac21cb13993c6e4f8709f23 p2p, bugfix: use NetPermissions::HasFlag() in CConnman::Bind() (Jon Atack)
Pull request description:
This is a bugfix follow-up to #16248 and #19191 that was noticed in #21506. Both v0.21 and master are affected.
Since #19191, noban is a multi-flag that implies download, so the conditional in `CConnman::Bind()` using a bitwise AND on noban will return the same result for both the noban status and the download status. This means that download peers are incorrectly not being added to local addresses because they are mistakenly seen as noban peers.
The second commit adds unit test coverage to illustrate and test the noban/download relationship and the `NetPermissions` operations involving them.
The final commit adds documentation and disallows calling `NetPermissions::ClearFlag()` with any second param other than `NetPermissionFlags` "implicit" -- per current usage in the codebase -- because `ClearFlag()` should not be called with any second param that is a subflag of a multiflag, e.g. "relay" or "download," as that would leave the result in an invalid state corresponding to none of the existing NetPermissionFlags. Thanks to Vasil Dimov for noticing this.

`static constexpr CMessageHeader::HEADER_SIZE` is already used in this file, `src/net.cpp`, in 2 instances. This commit replaces the remaining 2 integer values in the file with it and adds the explicit include header.

completion of partial merge done in dash#4164 as 56f1b2d (blocker
bitcoin#17938 was merged in dash#5246 as 00802bb)
## Motivation
As highlighted in https://github.com/dashpay/dash-issues/issues/52,
decoupling of `CFlatDB`-interacting components from managers of objects
like `CGovernanceManager` and `CSporkManager` is a key task for
achieving deglobalization of Dash-specific components.
The design of `CFlatDB` as a flat database agent relies on hooking into
the object's state its meant to load and store, using its
(de)serialization routines and other miscellaneous functions (notably,
without defining an interface) to achieve those ends. This approach was
taken predominantly for components that want a single-file cache.
Because of the method it uses to hook into the object (templates and the
use of temporary objects), it explicitly prevented passing arguments
into the object constructor, an explicit requirement for storing
references to other components during construction. This, in turn,
created an explicit dependency on those same components being available
in the global context, which would block the backport of bitcoin#21866,
a requirement for future backports meant to achieve parity in
`assumeutxo` support.
The design of these objects made no separation between persistent (i.e.
cached) and ephemeral (i.e. generated/fetched during initialization or
state transitions) data and the design of `CFlatDB` attempts to "clean"
the database by breaching this separation and attempting to access this
ephemeral data.
This might be acceptable if it is contained within the manager itself,
like `CSporkManager`'s `CheckAndRemove()` but is utterly unacceptable
when it relies on other managers (that, as a reminder, are only
accessible through the global state because of restrictions caused by
existing design), like `CGovernanceManager`'s `UpdateCachesAndClean()`.
This pull request aims to separate the `CFlatDB`-interacting portions of
these managers into a struct, with `CFlatDB` interacting only with this
struct, while the manager inherits the struct and manages
load/store/update of the database through the `CFlatDB` instance
initialized within its scope, though the instance only has knowledge of
what is exposed through the limited parent struct.
## Additional information
* As regards to existing behaviour, `CFlatDB` is written entirely as a
header as it relies on templates to specialize itself for the object it
hooks into. Attempting to split the logic and function definitions into
separate files will require you to explicitly define template
specializations, which is tedious.
* `m_db` is defined as a pointer as you cannot instantiate a
forward-declared template (see [this Stack Overflow
answer](https://stackoverflow.com/a/12797282) for more information),
which is done when defined as a member in the object scope.
* The conditional cache flush predicating on RPC _not_ being in the
warm-up state has been replaced with unconditional flushing of the
database on object destruction (@UdjinM6, is this acceptable?)
## TODOs
This is a list of things that aren't within the scope of this pull
request but should be addressed in subsequent pull requests
* [ ] Definition of an interface that `CFlatDB` stores are expected to
implement
* [ ] Lock annotations for all potential uses of members protected by
the `cs` mutex in each manager object and store
* [ ] Additional comments documenting what each function and member does
* [ ] Deglobalization of affected managers

Removed a flag m_block_relay_peer. Instead I call IsAddrRelayPeer() that
has same information now.
It changes logic introduced in #4888 due to dash-specific code.

090b75c14be6b9ba2efe38a17d141c6e6af575cb p2p: Avoid allocating memory for addrKnown where we don't need it (User)
Pull request description:
We should allocate memory for addrKnown filter only for those peers which are expected to participate in address relay.
Currently, we do it for all peers (including SPV and block-relay-only), which results in extra RAM where it's not needed.
Upd:
In future, we would still allow SPVs to ask for addrs, so allocation still will be done by default.
However, they will be able to opt-out via [this proposal](https://lists.linuxfoundation.org/pipermail/bitcoin-dev/2019-October/017428.html) and then we could save some more memory.
This PR still saves memory for block-relay-only peers immediately after merging.
Top commit has no ACKs.

*** Please remove the following help text before submitting: ***
Provide a general summary of your changes in the Title above
Pull requests without a rationale and clear improvement may be closed
immediately.
Please provide clear motivation for your patch and explain how it
improves
Dash Core user experience or Dash Core developer experience
significantly:
* Any test improvements or new tests that improve coverage are always
welcome.
* All other changes should have accompanying unit tests (see
`src/test/`) or
functional tests (see `test/`). Contributors should note which tests
cover
modified code. If no tests exist for a region of modified code, new
tests
should accompany the change.
* Bug fixes are most welcome when they come with steps to reproduce or
an
explanation of the potential issue as well as reasoning for the way the
bug
was fixed.
* Features are welcome, but might be rejected due to design or scope
issues.
If a feature is based on a lot of dependencies, contributors should
first
consider building the system outside of Dash Core, if possible.
