cmdserver: wrap 'pipe' mode server by service object

This is the stub for new mode that will listen for connections on unix domain
socket.

Though --daemon option is not banned in 'pipe' mode, it is useless because
the detached 'pipe' mode server exits immediately due to null stdin. Should
it abort if --daemon is specified with --cmdserver pipe or --stdio?

  $ echo "abortcommit = $abspath" >> $HGRCPATH

  $ hg init foo
  $ cd foo
  $ echo foo > foo
  $ hg add foo

mq may keep a reference to the repository so __del__ will not be
called and .hg/journal.dirstate will not be deleted:

  $ hg ci -m foo
  error: pretxncommit.nocommits hook failed: no commits allowed
  transaction abort!
  rollback completed
  abort: no commits allowed
  [255]
  $ hg ci -m foo
  error: pretxncommit.nocommits hook failed: no commits allowed
  transaction abort!
  rollback completed
  abort: no commits allowed
  [255]

  $ cd ..
