This allows us to both manually manipulate options and grab values from
ArgsManager (i.e. -blockmaxweight and -blockmintxfee config options)
when constructing BlockAssembler::Options. Prior to this change, the
only way to apply the config options is by ctoring BlockAssembler with
no options, which calls DefaultOptions().
fabf1cdb20 Use steady clock for bench logging (MacroFake)
faed342a23 scripted-diff: Rename time symbols (MacroFake)
Pull request description:
Instead of using `0.001` and similar constants to "convert" an int64_t to milliseconds, use the type-safe `Ticks<>` helper. Also, use steady clock instead of system clock, since the durations are used for benchmarking.

ACK fabf1cdb20 - validation bench output still looks sane.

b85af25f87 refactor: mempool: add MemPoolLimits::NoLimits() (stickies-v)
Pull request description:
Mempool currently considers 4 limits regarding ancestor and descendant count and size, which get passed around between functions quite a bit. This PR uses `CTxMemPool::Limits` introduced in https://github.com/bitcoin/bitcoin/pull/25290 to simplify those signatures and callsites.
The purpose of this PR is to improve readability and maintenance, without behaviour change.
As noted in the first commit "refactor: mempool: change MemPoolLimits members to uint", we currently have an underflow issue where a user could pass a negative `-limitancestorsize`, which is eventually cast to an unsigned integer. This behaviour already exists. Because it's orthogonal and to minimize scope, I think this should be fixed in a separate PR.

Simplifies function signatures by removing repetition of all the
ancestor/descendant limits, and increases readability by being
more verbose by naming the limits, while still reducing the LoC.
...also adjust callers
Changes:
- In BlockAssembler::CreateNewBlock, we now only lock m_mempool->cs and
call addPackageTxs if m_mempool is not nullptr
- BlockAssembler::addPackageTxs now takes in a mempool reference, and is
annotated to require that mempool's lock.
- In TestChain100Setup::CreateBlock and generateblock, don't construct
an empty mempool, just pass in a nullptr for mempool
Since UpdatePackagesForAdded is a helper function that's only used in
addPackageTxs we can make it static and avoid the unnecessary interface
and in-header lock annotation.
SkipMapTxEntry is a short helper function that's only used in
addPackageTxs, we can just inline it, keep the comments, and avoid the
unnecessary interface and lock annotations.
7036cf52aa Delete UpdatePackagesForAdded at beginning of addPackageTxs. (KevinMusgrave)
Pull request description:
In `CreateNewBlock` (in miner.cpp), `inBlock` is cleared before `addPackageTxs`, so `inBlock` will be empty in the first call to `UpdatePackagesForAdded`. I saw this brought up in these [PR review club logs](https://bitcoincore.reviews/24538) and there didn't seem to be a definitive answer for why the call is necessary. There's also an [old PR](https://github.com/bitcoin/bitcoin/pull/10200) where this change was going to be applied, but it got closed.
If `addPackageTxs` can be called when `inBlock` is not empty, then maybe a test should be added for that case. All the tests seem to pass with this deletion.

This decouples validation.cpp from netaddress.cpp (transitively,
timedata.cpp, and asmap.cpp).
This is important for libbitcoinkernel as:
- There is no reason for the consensus engine to be coupled with
netaddress, timedata, and asmap
- Users of libbitcoinkernel can now easily supply their own
std::function that provides the adjusted time.
See the src/Makefile.am changes for some satisfying removals.

Pull request description:
The only important commit is "Only load BlockMan in BlockMan member functions", everything else is all just small style changes.
Here's the commit message, reproduced:
```
This commit effectively splits the "load block index itself" logic from
"derive Chainstate variables from loaded block index" logic.
This means that BlockManager::LoadBlockIndex{,DB} will only load what's
relevant to the BlockManager.

Given the low possibility of a reorg reverting the segwit soft fork,
there is no need to check whether segwit is active here. Also,
TestBlockValidity is run on the block template after it has been
created.

- BlockAssembler::addPackageTxs()
- BlockAssembler::SkipMapTxEntry()
- BlockAssembler::UpdatePackagesForAdded()
These functions have thread safety lock annotations in
their declarations but are missing the corresponding
run-time lock assertions in their definitions.
Per doc/developer-notes.md: "Combine annotations in function
declarations with run-time asserts in function definitions."
