vsrc_buffer: add flags param to av_vsrc_buffer_add_video_buffer_ref
The new flags parameter allows to specify if the video ref to add
should overwrite the cache, if the flag is not set vsrc_buffer will
complain and abort; otherwise it will clean the already cached video
ref before to overwrite it, thus avoiding a leak.
