localrepo: add unbundle support
Localrepo now supports the unbundle method of pushing changegroups. We
plan to use the unbundle call for bundle2 so it is important that all
peers supports it. The `peer.unbundle` and `peer.addchangegroup` code
path have small difference so cause some test output changes. None of those
changes seems problematic.
