The fs.* files are already part of the libbitcoin_util library. With the
introduction of the fs_helpers.* it makes sense to move fs.* into the
util/ directory as well.

6666803c897e4ad27b45cb74e3a9aa74a335f1bf streams: Add AutoFile without ser-type and ser-version (MacroFake)
Pull request description:
This was done in the context of https://github.com/bitcoin/bitcoin/pull/25284 , but I think it also makes sense standalone.
The basic idea is that serialization type should not be initialized when it is not needed. Same for the serialization version.
So do this here for `AutoFile`. `CAutoFile` remains in places where it is not yet possible.

These files change infrequently, and not much header shuffling is required.
We don't add everything in src/util/ yet, because IWYU makes some
dubious suggestions, which I'm going to follow up with upstream.
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.

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.

DecopeAsmap is a pure utility function and doesn't have any
dependencies on addrman, so move it to util/asmap.
Reviewer hint: use:
`git diff --color-moved=dimmed-zebra --color-moved-ws=ignore-all-space`
This reverts commit eac6a3080d38cfd4eb7204ecd327df213958e51a ("refactor:
Rework asmap Interpret to avoid ptrdiff_t"), because it is UB to form a
past-the-end iterator, even if it is never dereferenced.
Then fix the compiler warning in a different way:
Instead of comparing an uint32_t against a signed ptrdiff_t, just
promote both to a type that can represent both types.
Even though in this case the ptrdiff_t should never hold a negative
value, the overhead from promotion should be negligible.

Pull request description:
This improves/documents the failure cases inside the asmap interpreter. None of the changes are bug fixes (they only change behavior for corrupted asmap files), but they may make things easier to follow.
In a second step, a sanity checker is added that effectively executes every potential code path through the asmap file, checking the same failure cases as the interpreter, and more. It takes around 30 ms to run for me for a 1.2 MB asmap file.
I've verified that this accepts asmap files constructed by https://github.com/sipa/asmap/blob/master/buildmap.py with a large dataset, and no longer accepts it with 1 bit changed in it.
