rust: Return HgError instead of RevlogError in revlog constructors
This leaves fewer cases for callers to handle, as RevlogError is more general

rhg: Align with Python on some revset parsing corner cases
In particular:
* A string of ASCII digits can be either an integer on a hex prefix
* The NULL node ID should convert to the NULL revision number

rust: Add a Filelog struct that wraps Revlog
Some filelog-specific logic is moved from code `rhg cat` into this struct
where it can better be reused.
Additionally, a missing end delimiter for metadata causes an error
to be returned instead of being silently ignored.

This deduplicates some common code.

rust: Keep lazily-initialized Changelog and Manifest log on the Repo object
That way if one of them is accessed multiple times it won’t be reopened
from the filesystem.

rust: Move lazy initialization of `Repo::dirstate_map` into a generic struct
More components of `Repo` will be added following the same pattern.

rust: Rename Manifest to Manifestlog, ManifestEntry to Manifest
This appears to match the terminology used in Python code
and on https://www.mercurial-scm.org/wiki/Manifest

rust: Add Repo::dirstate_map and use it in `rhg status`
This moves low-level dirstate wrangling out of the status command and into
a more reusable location.
The open dirstate map is lazily initialized and kept on the Repo object,
for reuse by sub-sequent calls.

rust: Switch to the memmap2-rs crate
https://github.com/RazrFalcon/memmap2-rs
This is a fork of the original memmap crate which appears to be unmaintained:
https://github.com/danburkert/memmap-rs/issues/90
This fork is the most popular according to https://crates.io/keywords/mmap

rust: Make OwningDirstateMap generic and move it into hg-core
This will enable using it in rhg too.
The `OwningDirstateMap::new_empty` constructor is generic and accepts a value
of any type that gives acces to a bytes buffer. That buffer must stay valid
as long as the value hasn’t been dropped, and must keep its memory address
even if the value is moved. The `StableDeref` marker trait encodes those
constraints. Previously no trait was needed because the value was always
of type `PyBytes` which we know satisfies those constraints.
The buffer type is ereased in the struct itself through boxing and
dynamic dispatch, in order to simplify other signatures that mention
`OwningDirstateMap`.
