This is part of the `libbitcoinkernel` project: #24303, https://github.com/bitcoin/bitcoin/projects/18
-----
As mentioned in the Stage 1 Step 2 description of [the `libbitcoinkernel` project](https://github.com/bitcoin/bitcoin/issues/24303), `ArgsManager` will not be part of `libbitcoinkernel`. Therefore, it is important that we remove any dependence on `ArgsManager` by code that will be part of `libbitcoinkernel`. This is the first in a series of PRs aiming to achieve this.
This PR removes `CTxMemPool+MempoolAccept`'s dependency on `ArgsManager` by introducing a `CTxMemPool::Options` struct, which is used to specify `CTxMemPool`'s various options at construction time.
These options are:
- `-maxmempool` -> `CTxMemPool::Options::max_size`
- `-mempoolexpiry` -> `CTxMemPool::Options::expiry`
- `-limitancestorcount` -> `CTxMemPool::Options::limits::ancestor_count`
- `-limitancestorsize` -> `CTxMemPool::Options::limits::ancestor_size`
- `-limitdescendantcount` -> `CTxMemPool::Options::limits::descendant_count`
- `-limitdescendantsize` -> `CTxMemPool::Options::limits::descendant_size`
More context can be gleaned from the commit messages. The important commits are:
- 56eb479ded8bfb2ef635bb6f3b484f9d5952c70d "pool: Add and use MemPoolOptions, ApplyArgsManOptions"
- a1e08b70f3068f4e8def1c630d8f50cd54da7832 "mempool: Pass in -maxmempool instead of referencing gArgs"
- 6f4bf3ede5812b374828f08fc728ceded2f10024 "mempool: Pass in -mempoolexpiry instead of referencing gArgs"
- 5958a7fe4806599fc620ee8c1a881ca10fa2dd16 "mempool: Introduce (still-unused) MemPoolLimits"
Reviewers: Help needed in the following commits (see commit messages):
- a1e08b70f3068f4e8def1c630d8f50cd54da7832 "mempool: Pass in -maxmempool instead of referencing gArgs"
- 0695081a797e9a5d7787b78b0f8289dafcc6bff7 "node/ifaces: Use existing MemPoolLimits"
Note to Reviewers: There are perhaps an infinite number of ways to architect `CTxMemPool::Options`, the current one tries to keep it simple, usable, and flexible. I hope we don't spend too much time arguing over the design here since that's not the point. In the case that you're 100% certain that a different design is strictly better than this one in every regard, please show us a fully-implemented branch.
-----
TODO:
- [x] Use the more ergonomic `CTxMemPool::Options` where appropriate
- [x] Doxygen comments for `ApplyArgsManOptions`, `MemPoolOptions`
-----
Questions for Reviewers:
1. Should we use `std::chrono::seconds` for `CTxMemPool::Options::expiry` and `CTxMemPool::m_expiry` instead of an `int64_t`? Something else? (`std::chrono::hours`?)
2. Should I merge `CTxMemPool::Limits` inside `CTxMemPool::Options`?

Define (and document) `NOMINMAX` once, rather than across multiple
source files.
Defining this prevents the definition of min/max macros when using
mingw-w64, which may conflict with unprefixed std::min/max usage. While
that might not be the case for us, we'd always prefer to use the standard
library in any case.

Pull request description:
This changes `LOCK(mutex)` for non-global, non-recursive mutexes to be annotated with the negative capability for the mutex it refers to, to prevent . clang applies negative capabilities recursively, so this helps avoid forgetting to annotate functions.
This can't reasonably be used for globals, because clang would require every function to be annotated with `EXCLUSIVE_LOCKS_REQUIRED(!g_mutex)` for each global mutex; so this introduces a trivial `GlobalMutex` subclass of `Mutex`, and reduces the annotations for both `GlobalMutex` to `LOCKS_EXCLUDED` which only catches trivial errors (eg (`LOCK(x); LOCK(x);`).

1d4122dfef init: Allow -proxy="" setting values (Ryan Ofsky)
Pull request description:
This drops the `No proxy server specified. Use -proxy=<ip> or -proxy=<ip:port>` error when a empty `-proxy=` command line argument, `bitcoin.conf` value, or `settings.json` value is specified, and just makes bitcoin connect and listen normally in these cases.
The error was originally added in https://github.com/bitcoin/bitcoin/pull/20003 to prevent a bare `-proxy` command line argument with no assignment from clearing proxy settings. But it was implemented in an overbroad way breaking empty `-proxy=` assignments as well.
The motivation for this change is to prevent a GUI bug that happens with https://github.com/bitcoin/bitcoin/pull/15936, reported in https://github.com/bitcoin/bitcoin/pull/15936#pullrequestreview-937685759 by vasild, that happens after a proxy setting is enabled and disabled in the GUI.

is used. (GUI code already backs up and resets the "guisettings.ini" file this
way, so this just makes the same behavior possible for "settings.json")

f64aa9c411 Disallow more unsafe string->path conversions allowed by path append operators (Ryan Ofsky)
Pull request description:
Add more `fs::path` `operator/` and `operator+` overloads to prevent unsafe string->path conversions on Windows that would cause strings to be decoded according to the current Windows locale & code page instead of the correct string encoding.
Update application code to deal with loss of implicit string->path conversions by calling `fs::u8path` or `fs::PathFromString` explicitly, or by just changing variable types from `std::string` to `fs::path` to avoid conversions altogether, or make them happen earlier.
In all cases, there's no change in behavior either (1) because strings only contained ASCII characters and would be decoded the same regardless of what encoding was used, or (2) because of the 1:1 mapping between paths and strings using the `PathToString` and `PathFromString` functions.
Motivation for this PR was just that I was experimenting with #24469 and noticed that operations like `fs::path / std::string` were allowed, and I thought it would be better not to allow them.

Fix GUI startup crash reported by Rspigler in
https://github.com/bitcoin/bitcoin/issues/24457 that happens if
settings.json contains an integer value for any of the configuration
options which GUI settings can currently clash with (-dbcache, -par,
-spendzeroconfchange, -signer, -upnp, -natpmp, -listen, -server, -proxy,
-proxy, -onion, -onion, -lang, and -prune).
Fix is a one-line change in ArgsManager::GetArg.
Let GetPathArg method be used more places for path arguments that have
default values, like "-settings" and BITCOIN_SETTINGS_FILENAME in the
next commit.
Also:
- Fix negated argument handling. Return path{} not path{"0"} when path
argument is negated.
- Add new tests for default and negated cases
- Move GetPathArg() method declaration next to GetArg() declarations.
The two methods are close substitutes for each other, so this should
help keep them consistent and make them more discoverable.
Use std::filesystem::rename() instead of std::rename(). We rely on the
destination to be overwritten if it exists, but std::rename()'s behavior
is implementation-defined in this case.

This should also fix an assert error if a -datadir with a trailing slash
is used on windows. This appears to be a real error and regression
introduced with #20744.
On windows (or at least wine), fs calls that actuallly access the
filesystem like fs::equivalent or fs::exists seem to treat directory
paths with trailing slashes as not existing, so it's necessary to
normalize these paths before using them. This fix adds a
path::lexically_normal() call to the failing assert so it passes.
Warning: Replacing fs::system_complete calls with fs::absolute calls
in this commit may cause minor changes in behaviour because fs::absolute
no longer strips trailing slashes; however these changes are believed to
be safe.

This commit does not change behavior in any way. See previous commit for
complete rationale, but these flags are being disabled because they
aren't implemented and will otherwise break backwards compatibility when
they are implemented.

Currently, ALLOW_{INT|BOOL|STRING} flags don't do any real validation,
so current uses of these flags are misleading and will also break
backwards compatibility whenever these flags are implemented in a future
PR (draft PR is #16545).
An additional complication is that while these flags don't do any real
settings validation, they do affect whether setting negation syntax is
allowed.
Fix this mess by disabling ALLOW_{INT|BOOL|STRING} flags until they are
implemented, and adding an unambiguous DISALLOW_NEGATION flag. This is
done in two commits, with this commit adding the DISALLOW_NEGATION flag,
and the next commit disabling the ALLOW_{INT|BOOL|STRING} flags.
There is no change in behavior. This just helps prepare for the
transition from boost::filesystem to std::filesystem by avoiding calls
to methods which will be unsafe after the transaction to std::filesystem
to due lack of a boost::filesystem::path::imbue equivalent and inability
to set a predictable locale.
