Bug#703726: [PATCH] libcogl12: SIGSEGV in cogl_onscreen_add_frame_callback

Hi, I can confirm the bug and this patch fixes it. Basicaly it crashed in cogl_onscreen_add_frame_callback because macro COGL_TAILQ_REMOVE in cogl_onscreen_remove_frame_callback incorrectly removed an element from queue and corrupted the queue and tail pointer. --- a/cogl/cogl-queue.h
