peer: introduce peer methods to prepare for peer classes
This introduces a peer method into all repository classes, which currently
simply returns self. It also changes hg.repository so it now raises an
exception if the supplied paths does not resolve to a localrepo or descendant.
Finally, all call sites are changed to use the peer and local methods as
appropriate, where peer is used whenever the code is dealing with a remote
repository (even if it's on local disk).
