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

  $ . "$TESTDIR/remotefilelog-library.sh"

Set up an extension to make sure remotefilelog clientsetup() runs
unconditionally even if we have never used a local shallow repo.
This mimics behavior when using remotefilelog with chg.  clientsetup() can be
triggered due to a shallow repo, and then the code can later interact with
non-shallow repositories.

  $ cat > setupremotefilelog.py << EOF
  > from mercurial import extensions
  > def extsetup(ui):
  >     remotefilelog = extensions.find(b'remotefilelog')
  >     remotefilelog.onetimeclientsetup(ui)
  > EOF

Set up the master repository to pull from.

  $ hg init master
  $ cd master
  $ cat >> .hg/hgrc <<EOF
  > [remotefilelog]
  > server=True
  > EOF
  $ echo x > x
  $ hg commit -qAm x

  $ cd ..

  $ hg clone ssh://user@dummy/master child -q

We should see the remotefilelog capability here, which advertises that
the server supports our custom getfiles method.

  $ cd master
  $ echo 'hello' | hg -R . serve --stdio | grep capa | identifyrflcaps
  exp-remotefilelog-ssh-getfiles-1
  x_rfl_getfile
  x_rfl_getflogheads
  $ echo 'capabilities' | hg -R . serve --stdio | identifyrflcaps ; echo
  exp-remotefilelog-ssh-getfiles-1
  x_rfl_getfile
  x_rfl_getflogheads
  

Pull to the child repository.  Use our custom setupremotefilelog extension
to ensure that remotefilelog.onetimeclientsetup() gets triggered.  (Without
using chg it normally would not be run in this case since the local repository
is not shallow.)

  $ echo y > y
  $ hg commit -qAm y

  $ cd ../child
  $ hg pull --config extensions.setuprfl=$TESTTMP/setupremotefilelog.py
