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
Differential Revision: https://phab.mercurial-scm.org/D11397

# XXX-CHG When running with python2 + chg this test tend to get stuck and end up
# as a time-out error. My effort to reproduce this outside of the CI failed. The
# test itself seems to pass fine, but never "complete". Debugging it is slow and
# tedious. This as a bad impact on the development process as most CI run end up
# wasting abotu 1h until that one fails.
#
# Pierre-Yves David, Augie Fackler and Raphaël Gomès all agreed to disable this
# case in that specific case until we figure this out (or we drop python2 o:-) )
#if no-py3 chg
$ echo 'skipped: this test get stuck on the CI with python2 + chg. investigation needed'
