Merge branch 'rs/lose-leak-pending' into maint
API clean-up around revision traversal.
* rs/lose-leak-pending:
commit: remove unused function clear_commit_marks_for_object_array()
revision: remove the unused flag leak_pending
checkout: avoid using the rev_info flag leak_pending
bundle: avoid using the rev_info flag leak_pending
bisect: avoid using the rev_info flag leak_pending
object: add clear_commit_marks_all()
ref-filter: use clear_commit_marks_many() in do_merge_filter()
commit: use clear_commit_marks_many() in remove_redundant()
commit: avoid allocation in clear_commit_marks_many()
