fac07f2038 node: Add reference to mempool in NodeContext (MarcoFalke)
Pull request description:
This is the first step toward making the mempool a global that is not initialized before main.
#### Motivation
Currently the mempool is a global that is initialized before the `main` function. This is confusing and easy to get wrong. E.g. the mempool constructor queries state that has not been initialized, like randomness (fixed), or command line arguments (not an issue last time I checked). Also without having the chainstate (chain tip) initialized first, it doesn't make conceptually sense to have a mempool, since the mempool builds txs on top of the utxo set (chain tip).
Finally, in the future someone might want to run a consensus-only full node (`-nowallet -noblockfilter -no... -nomempool` command line options) that only verifies blocks and updates the utxo set.
This is conceptually the same change that has already been done for the connection manager `CConnman`.

The function IsStandardTx() returns rejection reason "bare-multisig" if the
transaction has a bare multisig output and the policy flag fIsBareMultisigStd
is false (set by the boolean command-line argument "-permitbaremultisig" -- for
the unit test, we simply set the global flag variable directly).
Also remove a needless loop in DecodeBase58 to prune zeroes in the base256
output of the conversion. The number of zeroes is implied by keeping track
explicitly of the length during the loop.

Currently it is an alias to the global ::mempool and should be used as
follows.
* Node code (validation and transaction relay) can use either ::mempool
or node.mempool, whichever seems a better fit.
* RPC code should use the added convenience getter EnsureMempool, which
makes sure the mempool exists before use. This prepares the RPC code
to a future where the mempool might be disabled at runtime or compile
time.
* Test code should use m_node.mempool directly, as the mempool is always
initialized for tests.
Also rename the "result_complete" variable in GetSettingsList() to "done" to be
more consistent with GetSetting().
This change doesn't affect current behavior but could be useful in the future
to support dynamically changing settings at runtime and adding new settings
sources, because it lets high priority sources reset settings back to default
(see test).
By removing a special case for null, this change also helps merge code treat
settings values more like black boxes, and interfere less with settings parsing
and retrieval.

Pull request description:
This is a refactoring-only change that makes it easier to add a new settings source.
This PR doesn't change behavior. The [`util_ArgsMerge`](deb2327b43/src/test/util_tests.cpp (L626-L822)) and [`util_ChainMerge`](deb2327b43/src/test/util_tests.cpp (L843-L924)) tests added in #15869 and #15988 were written specifically to confirm that ArgsManager settings are parsed, merged, and returned the same way before and after this change.
This change:
- Makes it easier to add new settings sources that can get merged with existing sources (see 70675c3e4975203ad6222ba2b00c83b4e4213793 from #15935).
- Separates parsing of settings from merging of settings, and deduplicates merging code so it doesn't happen five different places ([GetArg](c459c5f701/src/util/system.cpp (L221-L244)), [GetNetBoolArg](c459c5f701/src/util/system.cpp (L255-L261)), [GetArgs](c459c5f701/src/util/system.cpp (L460-L467)), [IsArgNegated](c459c5f701/src/util/system.cpp (L482-L491)), [GetUnsuitableSectionOnlyArgs](c459c5f701/src/util/system.cpp (L343-L352))) in inconsistent ways.
- Documents and tests current strange merging behaviors, so they be cleaned up in the future if resulting code simplifications and UX improvements warrant loss of backwards compatibility. The newly documented behaviors are: command line [ignored arguments](69d44f3cc7/src/util/system.cpp (L323-L326)) and [more ignored arguments](69d44f3cc7/src/util/settings.cpp (L67-L72)), and config file [reverse precedence](69d44f3cc7/src/util/settings.cpp (L61-L65)), [inconsistently applied top-level settings](69d44f3cc7/src/util/settings.cpp (L55-L59)), and [zombie values](69d44f3cc7/src/util/settings.cpp (L101-L108)).
The original motivation for this change was to make it easy to add a new persistent setting source without introducing more bugs and inconsistencies. Two commits building on top of this to add a persistent `-wallet` setting are pretty straightforward and show how the new code can be extended:
* 70675c3e4975203ad6222ba2b00c83b4e4213793 from #15935 – _Add \<datadir>/settings.json persistent settings storage_
* 04c80c40df9fc6f4734ba238ea7f65607cf88089 from #15937 – _Add loadwallet and createwallet RPC load_on_startup options_

Pull request description:
Work starter to remove Chain::Lock interface by adding m_last_block_processed_height in CWallet and m_block_height in CMerkleTx to avoid GetDepthInMainChain having to keep a lock . Once this one done, it should ease work to wipe out more cs_main locks from wallet code.
I think it's ready for a first round of review before to get further.
- `BlockUntilSyncedToCurrent` : restrain isPotentialTip to isTip because we want to be sure that wallet see BlockDisconnected callbacks if its height differs from the Chain one. It means during a reorg, an RPC could return before the BlockDisconnected callback had been triggered. This could cause a tx that had been included in the disconnected block to be displayed as confirmed, for example.
~~- `AbandonTransaction` : in case of conflicted tx (nIndex = -1), we set its m_block_height to the one of conflicting blocks, but if this height is superior to CWallet::m_last_block_processed_height, that means tx isn't conflicted anymore so we return 0 as tx is again unconfirmed~~ After #16624, we instead rely on Confirmation.
~~- `AddToWalletIfInvolvingMe`: in case of block disconnected, transactions are added to mempool again, so we need to replace old txn in `mapWallet` with a height set to zero so we remove check on block_hash.IsNull~~ Already done in #16624

Get rid of settings merging code in util/system.cpp repeated 5 places,
inconsistently:
- ArgsManagerHelper::GetArg
- ArgsManagerHelper::GetNetBoolArg
- ArgsManager::GetArgs
- ArgsManager::IsArgNegated
- ArgsManager::GetUnsuitableSectionOnlyArgs
Having settings merging code separated from parsing simplifies parsing somewhat
(for example negated values can simply be represented as false values instead
of partially cleared or emply placeholder lists).
Having settings merge happen one place instead of 5 makes it easier to add new
settings sources and harder to introduce new inconsistencies in the way
settings are merged.
This commit does not change behavior in any way.
CheckInputs() used to check no double spends, scripts & sigs and amounts. Since

Sorry for clickbait, this is only a move-only scripted-diff commit and one documentation commit.
Longer term, someone who knows something about build systems can make this an actual library. Motivation for this is that each module gets compiled for each target that includes it.

Please provide clear motivation for your patch and explain how it improves
Bitcoin Core user experience or Bitcoin 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 Bitcoin Core, if possible.
* Refactoring changes are only accepted if they are required for a feature or
bug fix or otherwise improve developer experience significantly. For example,
most "code style" refactoring changes require a thorough explanation why they
are useful, what downsides they have and why they *significantly* improve
developer experience or avoid serious programming bugs. Note that code style
is often a subjective matter. Unless they are explicitly mentioned to be
preferred in the [developer notes](/doc/developer-notes.md), stylistic code
changes are usually rejected.

Bitcoin Core has a thorough review process and even the most trivial change
