templates: change {obsolete} to emit only "obsolete" or ""

The {obsolete} template function can currently emit "stable",
"unstable", "extinct", or "suspended".

The distinction between "extinct" and "suspended" seems likely to be
more confusing that enlightening, and "stable" and "unstable" are not
even obsolete.

Let's simplify it to just emit "obsolete" for obsolete changesets and
"" for others. That will also make it much easier to test for obsolete
changsets and do things like "if(obsolete, obsolete, troubles)".

  $ cat >> $HGRCPATH <<EOF
  > [extensions]
  > hgext.graphlog=
  > EOF
  $ echo "evolve=$(echo $(dirname $TESTDIR))/hgext/evolve.py" >> $HGRCPATH

  $ glog() {
  >   hg glog --template '{rev}:{node|short}@{branch}({separate("/", obsolete, phase)}) {desc|firstline}\n' "$@"
  > }

  $ hg branch bar
  marked working directory as branch bar
  (branches are permanent and global, did you want a bookmark?)

Test uncommit without argument, should be a no-op
