test-lfs: add tests covering local exchanges

The root issue here is that requirements are not exchanged and preserved on
push/pull.  This can be handled with a changegroup hook.  Testing for remote
exchanges is much more extensive (it's possible for one process or the other to
not have the extension loaded at all), so it is added separately.

#require killdaemons

Test wire protocol unbundle with hashed heads (capability: unbundlehash)

  $ cat << EOF >> $HGRCPATH
  > [devel]
  > # This tests is intended for bundle1 only.
  > # bundle2 carries the head information inside the bundle itself and
  > # always uses 'force' as the heads value.
  > legacy.exchange = bundle1
  > EOF

Create a remote repository.

  $ hg init remote
  $ hg serve -R remote --config web.push_ssl=False --config web.allow_push=* -p $HGPORT -d --pid-file=hg1.pid -E error.log -A access.log
  $ cat hg1.pid >> $DAEMON_PIDS

Clone the repository and push a change.

  $ hg clone http://localhost:$HGPORT/ local
  no changes found
  updating to branch default
  0 files updated, 0 files merged, 0 files removed, 0 files unresolved
  $ touch local/README
  $ hg ci -R local -A -m hoge
  adding README
  $ hg push -R local
  pushing to http://localhost:$HGPORT/

Ensure hashed heads format is used.
The hash here is always the same since the remote repository only has the null head.

  $ cat access.log | grep unbundle
  * - - [*] "POST /?cmd=unbundle HTTP/1.1" 200 - x-hgarg-1:heads=686173686564+6768033e216468247bd031a0a2d9876d79818f8f* (glob)

Explicitly kill daemons to let the test exit on Windows

  $ killdaemons.py
