template: add successors template

Add a 'successorssets' template that returns the list of all closest known
sucessorssets for a changectx. The elements of the list are changesets.

The "closest successors" are the first locally known revisions encountered
while, walking successors markers. It uses successorsets previously modified
to support the closest argument.

This logic respect repository filtering. So hidden revision will be skipped by
this logic unless --hidden is specified. Since we only display the visible
predecessors, this template will not display anything in most case. It makes a
good candidate for inclusion in the default log output.

I updated the test-obsmarker-template.t test file introduced with the
predecessors template to test successorssets template.

#require darcs

  $ echo "[extensions]" >> $HGRCPATH
  $ echo "convert=" >> $HGRCPATH
  $ DARCS_EMAIL='[e-mail]'; export DARCS_EMAIL

initialize darcs repo

  $ mkdir darcs-repo
  $ cd darcs-repo
  $ darcs init -q
  $ echo a > a
  $ darcs record -a -l -m p0
  Finished recording patch 'p0'
  $ cd ..

branch and update

  $ darcs get -q darcs-repo darcs-clone >/dev/null
  $ cd darcs-clone
  $ echo c >> a
  $ echo c > c
  $ darcs record -a -l -m p1.1
  Finished recording patch 'p1.1'
  $ cd ..

skip if we can't import elementtree

  $ if hg convert darcs-repo darcs-dummy 2>&1 | grep ElementTree > /dev/null; then
  >     echo 'skipped: missing feature: elementtree module'
  >     exit 80
  > fi

update source

  $ cd darcs-repo
  $ echo b >> a
  $ echo b > b
  $ darcs record -a -l -m p1.2
  Finished recording patch 'p1.2'

  $ darcs pull -q -a --no-set-default ../darcs-clone
  Backing up ./a(*) (glob)
  We have conflicts in the following files:
  ./a
   (?)
  $ sleep 1
  $ echo e > a
  $ echo f > f
  $ mkdir dir
  $ echo d > dir/d
  $ echo d > dir/d2
  $ darcs record -a -l -m p2
  Finished recording patch 'p2'

test file and directory move

  $ darcs mv -q f ff

Test remove + move

  $ darcs remove -q dir/d2
  $ rm dir/d2
  $ darcs mv -q dir dir2
  $ darcs record -a -l -m p3
  Finished recording patch 'p3'

The converter does not currently handle patch conflicts very well.
When they occur, it reverts *all* changes and moves forward,
letting the conflict resolving patch fix collisions.
Unfortunately, non-conflicting changes, like the addition of the
"c" file in p1.1 patch are reverted too.
Just to say that manifest not listing "c" here is a bug.
