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.
