rust: add a README

In particular to explain how to build any of the rust. It's neither
obvious, nor easy to find out, nor easy to determine if you did it
right without some documentation.

Test variable expansion
-----------------------

Subrepository paths shouldn't be expanded, but we fail to handle them
properly. Any local repository paths are expanded.

on commit:

  $ mkdir envvar
  $ cd envvar
  $ hg init main
  $ cd main
  $ hg init sub1
  $ cat <<'EOF' > sub1/hgrc
  > [hooks]
  > log = echo pwned
  > EOF
  $ hg -R sub1 ci -qAm 'add sub1 files'
  $ hg -R sub1 log -r. -T '{node}\n'
  39eb4b4d3e096527668784893a9280578a8f38b8
  $ echo '$SUB = sub1' >> .hgsub
  $ SUB=sub1 hg ci -qAm 'add subrepo "$SUB"'
  abort: subrepo path contains illegal component: $SUB
  [255]

  $ cd ..

on clone (and update) with various substitutions:

  $ hg clone -q main main2
  abort: subrepo path contains illegal component: $SUB
  [255]
  $ ls main2

  $ SUB=sub1 hg clone -q main main3
  abort: subrepo path contains illegal component: $SUB
  [255]
  $ ls main3

  $ SUB=sub2 hg clone -q main main4
  abort: subrepo path contains illegal component: $SUB
  [255]
  $ ls main4

on clone empty subrepo into .hg, then pull (and update), which at least fails:

  $ SUB=.hg hg clone -qr0 main main5
  abort: subrepo path contains illegal component: $SUB
  [255]
  $ ls main5

  [255]
  $ cat main5/.hg/hgrc | grep pwned
  [1]

on clone (and update) into .hg, which at least fails:

  $ SUB=.hg hg clone -q main main6
  abort: subrepo path contains illegal component: $SUB
  [255]
  $ ls main6
  $ cat main6/.hg/hgrc | grep pwned
  [1]

on clone (and update) into .hg/* subdir:

  $ SUB=.hg/foo hg clone -q main main7
  abort: subrepo path contains illegal component: $SUB
  [255]
  $ ls main7
  $ test -d main7/.hg/.hg
  [1]

on clone (and update) into outer tree:

  $ SUB=../out-of-tree-write hg clone -q main main8
  abort: subrepo path contains illegal component: $SUB
  [255]
  $ ls main8

on clone (and update) into e.g. $HOME, which doesn't work since subrepo paths
are concatenated prior to variable expansion:

  $ SUB="$TESTTMP/envvar/fakehome" hg clone -q main main9
  abort: subrepo path contains illegal component: $SUB
  [255]
  $ ls main9 | wc -l
  \s*0 (re)

  $ ls
  main
  main2
  main3
  main4
  main5
  main6
  main7
  main8
  main9
  $ cd ..

Test tilde
----------

The leading tilde may be expanded to $HOME, but it can be a valid subrepo
path in theory. However, we want to prohibit it as there might be unsafe
handling of such paths.

on commit:

  $ hg init tilde
  $ cd tilde
  $ hg init './~'
  $ echo '~ = ~' >> .hgsub
  $ hg ci -qAm 'add subrepo "~"'
  abort: subrepo path contains illegal component: ~
