  branch: drop unused worktrees variable
  fetch: stop passing around unused worktrees variable
  branch: fix branch_checked_out() leaks
  branch: use branch_checked_out() when deleting refs
  fetch: use new branch_checked_out() and add tests
  branch: check for bisects and rebases
  branch: add branch_checked_out() helper

* - start_commitish is the commit-ish, in repository r, that determines
* which commits the branches will point to. The superproject branch
* will point to the commit of start_commitish and the submodule
* branches will point to the gitlink commit oids in start_commitish's
* tree.
*
* - tracking_name is the name of the ref, in repository r, that will be
* used to set up tracking information. This value is propagated to
* all submodules, which will evaluate the ref using their own ref
* stores. If NULL, this defaults to start_commitish.
*
* When this function is called on the superproject, start_commitish
* can be any user-provided ref and tracking_name can be NULL (similar
* to create_branches()). But when recursing through submodules,
* start_commitish is the plain gitlink commit oid. Since the oid cannot
* be used for tracking information, tracking_name is propagated and
* used for tracking instead.
