revset: add a utility for obtaining the source of a given rev
graft, transplant and rebase all embed a different type of source marker in
extra, and each with a different name. The current implementation of each is
such that there will never be more than one of these markers on a node.
Note that the rebase marker can only be resolved if the source is
still present, which excludes the typical rebase usage (without
--keep) from consideration (unless the resulting bundle in
strip-backup is overlayed). There probably isn't any reason to use
rebase --keep as a substitute for transplant or graft at this point,
but maybe there was at one point and there are even a few rebases in
the hg repo, so it may be of historical interest.
