hgweb: display fate of obsolete changesets

Operations that obsolete changesets store enough metadata to explain what
happened after the fact. One way to get that metadata is showsuccsandmarkers
function, which returns a list of successors of a particular changeset and
appropriate obsolescence markers.

Templates have a set of experimental functions that have names starting with
obsfate. This patch uses some of these functions to interpret output of
succsandmarkers() and produce human-friendly messages that describe what
happened to an obsolete changeset, e.g. "pruned" or "rewritten as
6:3de5eca88c00".

In commonentry(), succsandmarkers property is made callable so it's only
executed on demand; this saves time when changeset is not obsolete, and also in
e.g. /shortlog view, where there are a lot of changesets, but we don't need to
show each and every one in detail.

In spartan theme, succsandmarkers is used instead of the simple "obsolete:
yes", in other themes a new line is added to /rev page.
