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>
