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:
This PR makes 2 distinct changes around `CWallet::SetUsedDestinationState`:

- 2nd change is to support, in the best case, just a wallet database flush when transaction is added to the wallet.

I might have missed something, but I didn't see a place where multiple batches were used previously and a single batch was used now. So the main benefit of this change appears to be removing a recursive lock? And maybe moving toward a consistent convention for passing batch instances?

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.
Implement merging of settings from different sources (command line and config
file) separately from parsing code in system.cpp, so it is easier to add new
sources.
Document current inconsistent merging behavior without changing it.
This commit only adds new settings code without using it. The next commit calls
the new code to replace existing code in system.cpp.

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.

Pull request description:
Speed up rpc_fundrawtransaction.py
Most of the time in rpc_fundrawtransaction.py is spent waiting for
unconfirmed transactions to propagate. Net processing adds a poisson
random delay to the time it will INV transactions with a mean interval
of 5 seconds. Calls like the following:
```
self.nodes[2].sendrawtransaction(signedTx['hex'])
self.sync_all()
self.nodes[1].generate(1)
````
will therefore introduce a delay waiting for the mempools to sync.
Instead just generate the block on the node that sent the transaction:
```
self.nodes[2].sendrawtransaction(signedTx['hex'])
self.nodes[2].generate(1)
```
rpc_fundrawtransaction.py is not intended to be a test for transaction
relay, so it's ok to do this.

The global nScriptCheckThreads int is confusing and is only needed for
its int-ness in AppInitMain. Move all `-par` parsing logic there and
replace the int nScriptCheckThreads with a bool
g_parallel_script_checks.
Also tidy up logic and improve comments.
This was only added in c1dde3a949 to match
behaviour when `encryptwallet` would restart the node. It's not required
for the test (and slows things down).
We don't remove yet Chain locks as we need to preserve lock
order with CWallet one until swapping at once to avoid
deadlock failures (spotted by --enable-debug)
is exact match
In the next commit, we start using BlockConnected/BlockDisconnected
callbacks to establish tx depth, rather than querying the chain
directly.
Currently, BlockUntilSyncedToCurrentChain will return early if
the best block processed by the wallet is a descendant of the node'tip.
That means that in the case of a re-org, it won't wait for the
BlockDisconnected callbacks that have been enqueued during the re-org
but have not yet been triggered in the wallet.
Change BlockUntilSyncedToCurrentChain to only return early if the
wallet's m_last_block_processed matches the tip exactly. This ensures
that there are no BlockDisconnected or BlockConnected callbacks
in-flight.
At wallet loading, we rely on chain state querying to retrieve
height of txn, to do so we ensure that lock order is respected
between cs_main and cs_wallet.
If wallet loaded is the wallet-tool one, all wallet txn will
show up with a height of zero. It doesn't matter as confirmation
height is not used by wallet-tool.
Reorder arguments and document Confirmation calls to avoid
ambiguity.

3645e4ca00 Add missing newline in util_ChainMerge test (Russell Yanofsky)
Pull request description:
This was causing a lot of test cases not not be very meaningful because
multiple configuration options were combined into one line.
The changes in test output with this fix make sense and look like:
```diff
- testnet=1 regtest=1 || test
+ testnet=1 regtest=1 || error: Invalid combination of -regtest, -testnet and -chain. Can use at most one.
```

*** Please remove the following help text before submitting: ***
Pull requests without a rationale and clear improvement may be closed

<!--
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
needs to pass a lot of eyes and requires non-zero or even substantial time
effort to review. There is a huge lack of active reviewers on the project, so
patches often sit for a long time.
