exchange: add fast path for subrepo check on push

Try to check if .hgsub and .hgsubstate exist at all before looking
for them in every changeset to be pushed. The latter can be quite
expensive for large repositories and the existance check is almost free.

#require no-windows no-rhg

XXX-RHG this test hangs if `hg` is really `rhg`. This was hidden by the use of
`alias hg=rhg` by run-tests.py. With such alias removed, this test is revealed
buggy. This need to be resolved sooner than later.

Kludge to emulate timeout(1) which is not generally available.

Set up repository
  $ hg init repo
  $ cd repo
  $ cat >> $HGRCPATH << EOF

  press ^C again to terminate immediately (dangerous)
