archive: add branch and tag informations to the .hg_archival.txt file

Up to this changeset, only the repo (first node) and current node hash where
printed. This adds also the named branch and tags.
Tags could be local or global tags. If multiple tags exist on this changeset,
they will be displayed one by line.
If the changeset has no tag, the latest tag in history (most recent tag in
ancestors) will be displayed instead, along to the longest distance to it.
