subrepo: pull revisions on demand when archiving hg subrepos

Before, running 'hg archive -S' could result in

 abort: unknown revision '65903cebad86f1a84bd4f1134f62fa7dcb7a1c98'!

if a subrepo was missing completely or had missing changesets. Now,
the missing changesets will be pulled or cloned as appropriate.

This make Mercurial subrepos match Git subrepos which already took
care to fetch any missing commits before starting the archive.

Create test repository:

  $ hg init repo
  $ cd repo
  $ echo x1 > x.txt

  $ hg init foo
  $ cd foo
  $ echo y1 > y.txt

  $ hg init bar
  $ cd bar
  $ echo z1 > z.txt

  $ cd ..
  $ echo 'bar = bar' > .hgsub

  $ cd ..
  $ echo 'foo = foo' > .hgsub

Add files --- .hgsub files must go first to trigger subrepos:

  $ hg add -S .hgsub
  $ hg add -S foo/.hgsub
  $ hg add -S foo/bar
  adding foo/bar/z.txt
  $ hg add -S
  adding x.txt
  adding foo/y.txt

Test recursive status without committing anything:

  $ hg status -S
  A .hgsub
  A foo/.hgsub
  A foo/bar/z.txt
  A foo/y.txt
  A x.txt

Test recursive diff without committing anything:

  $ hg diff --nodates -S foo
  diff -r 000000000000 foo/.hgsub
  --- /dev/null
  +++ b/foo/.hgsub
