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).
