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

Check local clone
==================
The logic is close enough of uncompressed.
This is present here to reuse the testing around file with "special" names.
$ hg clone server local-clone
updating to branch default
1088 files updated, 0 files merged, 0 files removed, 0 files unresolved
Check that the clone went well
$ hg verify -R local-clone
checking changesets
checking manifests
crosschecking files in changesets and manifests
checking files
checked 3 changesets with 1088 changes to 1088 files
Check uncompressed
==================
Cannot stream clone when server.uncompressed is set
