fa87f8feb7 doc: Clarify C++20 comments (MarcoFalke)
Pull request description:
Turns out "class template argument deduction for aggregates" is one of the few things implemented only in recent compilers, see https://en.cppreference.com/w/cpp/compiler_support/20
So clarify the comments.

This has outlived its usefulness, doesn't gel well with
newer compilers & `-flto` related options, i.e thin vs full, or `=auto`,
and having `-flto` as the only option means that sometimes this just
needs to be worked around, i.e in oss-fuzz:
https://github.com/google/oss-fuzz/blob/master/projects/bitcoin-core/build.sh.
While it was convenient when `-flto` was newer, support for `-flto` is now
in all compilers we use, and there's also no-longer any real need
for us to treat `-flto` different to any other optimization option.
Remove it, to remove build complexity, and so there's no need
to port a similar option to CMake.
Note that the LTO option remains in depends, because we still a way to
build packages that have LTO specific patches/options.
If we decide to merge this, I'll follow up downstream in oss-fuzz first,
to make sure we don't break the build.
Replace it with a more explicit DISABLE_OPTIMIZED_SHA256 and clean up some.
The macro was originally used by libbitcoinconsensus which opts out of
optimized sha256 for the sake of simplicity.
Also remove the BUILD_BITCOIN_INTERNAL define from libbitcoinkernel for now
as it does not export an api. When it does we can pick a less confusing define
to control its exports.
Removing the define should have the effect of enabling sha256 optimizations
for the kernel.
fa46cc22bc Remove deprecated -rpcserialversion (MarcoFalke)
Pull request description:
The flag is problematic for many reasons:
* It is deprecated
* It is a global flag, requiring a restart to change, as opposed to a flag that can be set on each RPC invocation
* It may be hidden in config files by accident, hard to debug, causing LND crashes and bugs, see https://github.com/bitcoin/bitcoin/issues/28730#issuecomment-1780940868
* It makes performance improvements harder to implement: https://github.com/bitcoin/bitcoin/pull/17529#issuecomment-556082818
Fix all issues by removing it.
If there is a use-case, likely a per-RPC flag can be added, if needed.

29fde0223a Squashed 'src/secp256k1/' changes from 199d27cea3..efe85c70a2 (fanquake)
Pull request description:
This includes changes from the 0.4.1 release: https://github.com/bitcoin-core/secp256k1/releases/tag/v0.4.1.
> The point multiplication algorithm used for ECDH operations (module ecdh) was replaced with a slightly faster one.
> Optional handwritten x86_64 assembly for field operations was removed because modern C compilers are able to output more efficient assembly. This change results in a significant speedup of some library functions when handwritten x86_64 assembly is enabled (--with-asm=x86_64 in GNU Autotools, -DSECP256K1_ASM=x86_64 in CMake), which is the default on x86_64. Benchmarks with GCC 10.5.0 show a 10% speedup for secp256k1_ecdsa_verify and secp256k1_schnorrsig_verify.

Pull request description:
This is a simple PR that does two things
1. Fixes #29000 by waiting for the fee estimator to catch up after `removeForBlock` calls before calling `estimateFee` in the `BlockPolicyEstimates` unit test.
2. Addressed some outstanding review comments from #28368
- Updated `NewMempoolTransactionInfo::m_from_disconnected_block` to `NewMempoolTransactionInfo::m_mempool_limit_bypassed` which now correctly indicates what the boolean does.
- Changed input of `processTransaction`'s tx_info `m_submitted_in_package` input from false to fuzz data provider boolean.
- Fixed some typos, and update incorrect comment

In reality some mempool transaction might be submitted in a package,
so change m_submitted_in_package to fuzz data provider boolean just like
m_has_no_mempool_parents.
The boolean indicates whether the transaction was added without enforcing mempool
fee limits. m_mempool_limit_bypassed is the correct variable name.
Also changes NewMempoolTransactionInfo booleans descriptions to the format that
is consistent with the codebase.
This affects manual connections made either with -connect, or with
-addnode provided as a bitcoind config arg (the addnode RPC has an
extra option for v2).
We don't necessarily know if our peer supports v2, but will reconnect
with v1 if they don't. In order to do that, improve the reconnection
behavior such that we will reconnect after a sleep of 500ms
(which usually should be enough for our peer to send us their
version message).
Making the `GenerateRandomKey` helper available to other modules via
key.{h.cpp} allows us to create random private keys directly at
instantiation of CKey, in contrast to the two-step process of creating
the instance and then having to call `MakeNewKey(...)`.

This is fine. However, it would be more helpful for developers and more accurate by the compiler to explain why each function is not selected.
Fix this by using C++20 concepts where appropriate.

These provide simple and clear ways to write the most common logging
operations:
LogInfo("msg");
LogDebug(BCLog::LogFlags::NET, "msg");
LogError("msg");
LogWarning("msg");
LogTrace(BCLog::LogFlags::NET, "msg");
For cases where the level cannot be hardcoded, LogPrintLevel(category,
level, ...) remains available.
It's not necessary to set up an entire CWallet just so we can get access
to the WalletDatabase and read the records. Instead we can go one level
lower and make just a WalletDatabase.
When there is a wallet loading error, it could be a noncritical one so
it is not necessary to make wallet_instance a nullptr. The wallet can
still go on with normal operation in that case, as we do for loading in
bitcoind and bitcoin-qt.
8dec9c560b wallet, mempool: propagete `checkChainLimits` error message to wallet (ismaelsadeeq)
Pull request description:
* Requested in [#28391 comment](https://github.com/bitcoin/bitcoin/pull/28391#discussion_r1382997719)
* The error message is static when a new transaction is created and package limit is reached.
`Transaction has too long of a mempool chain`
While the [`CTxMempool::CheckPackageLimits`](5800c558eb/src/txmempool.cpp (L199)) provide explicit information about the error message.
* This PR updates [`CTxMempool::CheckPackageLimits`](5800c558eb/src/txmempool.cpp (L199)) return type to `util::Result<void>`, `CheckPackageLimits` now returns void when package limit is not hit, and returns the error string whenever package limit is hit instead of using out parameter `errString`.
* The PR updates [`checkChainLimits`](5800c558eb/src/node/interfaces.cpp (L703)) return type to `util::Result<void>`.
* Now the wallet `CreateTransactionInternal` will have access to the package limit error string whenever its hit.
* Also Updated functional test to reflect the error message from `CTxMempool::CheckPackageLimits` output.

This option tells the logging system to always include a "[cat:level]"
prefix, so [net] becomes [net:debug], LogInfo/LogPrint statements will have
an [all:info] prefix, and LogWarning and LogError logs will become
[all:warning] and [all:error]. This may be easier for automated parsing
of logs, particularly if additional prefixes such as thread or source
location are enabled.
Previously Info-level logging when a category was specified (via
LogPrintLevel) would only print the corresponding log message if
`-debug=category` were specified, while Info-level logging without a
category would always be printed. Make this more consistent by having
Info messages always be logged, whether they include a category or not.
