revlog: move references to revlog.hash to inside the revlog class
This will make it possible for subclasses to have different hashing
schemes when appropriate. I anticipate using this in manifests.
Note that there's still one client of mercurial.revlog.hash() outside
of revlog: mercurial.context.memctx uses it to construct the file
entries in an in-memory manifest. I don't think this will be a problem
in the immediate future, so I've left it as-is.
