The implementation came with two flavors, where watcher could either specify a tag or no tag. That resulted in different usage patterns and behavior. Handles with tag are indexed by a dictionary and de-duplicated. Also the intended pattern is to delete them with nm_netns_watcher_remove_all(), Currently, nm_netns_watcher_remove_handle() was not permissible to tag-full handles, because of the de-duplication and because handles had no ref-counting implemented (the latter would be fixable, so nm_netns_watcher_remove_handle() would be made to work). On the other hand, handles without tag are never de-duplicated. They are also not indexed, so nm_netns_watcher_remove_all() doesn't work for them. They could only be removed via nm_netns_watcher_remove_handle(). Currently, the only user of the API will use tag-full handles. Drop the unused API. This is done as a separate commit, to potentially revert and restore tag-less handles (after they were already implemented).
