release
Attempts to release the permission represented by @permission.
The precise method by which this happens depends on the permission and the underlying authentication mechanism. In most cases the permission will be dropped immediately without further action.
You should check with g_permission_get_can_release() before calling this function.
If the permission is released then true is returned. Otherwise, false is returned and @error is set appropriately.
This call is blocking, likely for a very long time (in the case that user interaction is required). See g_permission_release_async() for the non-blocking version.
