changelog: add a new method to get files modified by a changeset

This patch adds a new method "readfiles" to get the files modified by a
changeset. It extracts some logic from "read" to only return the files modified
by a changeset as efficiently as possible. This is used in the next patch to
speed up hg log <file|folder>

    def add(self, manifest, files, desc, transaction, p1, p2,
                  user, date=None, extra=None):
        # Convert to UTF-8 encoded bytestrings as the very first
        # thing: calling any method on a localstr object will turn it
        # into a str object and the cached UTF-8 string is thus lost.
