ref-filter: implement '--contains' option
'tag -l' and 'branch -l' have two different ways of finding out if a certain ref contains a commit. Implement both these methods in ref-filter and give the caller of ref-filter API the option to pick which implementation to be used. 'branch -l' uses 'is_descendant_of()' from commit.c which is left as the default implementation to be used. 'tag -l' uses a more specific algorithm since ffc4b80. This implementation is used whenever the 'with_commit_tag_algo' bit is set in 'struct ref_filter'.
