      hook_list - a #GHookList
      hook - the current #GHook
      may_be_in_call - %TRUE if hooks which are currently running (e.g. in another thread) are considered valid. If set to %FALSE, these are skipped

      from the #GHookList and g_hook_free() is called to free it.
      Parameter:
      hook_list - a #GHookList
      hook - the #GHook to unref
