patch

In order to seek FLV streams, flvdemux creates a seek index;
however, this index is not created if upstream is not seekable.
gst_flv_demux_check_seekability was copied nearly verbatim from
GstBaseParse.

This commit adds QUERY_SEEKING handling to queue2, so RTMP live
streams become seekable when a queue2 in download or ringbuffer
mode is inserted:

rtmpsrc ! queue2 ! flvdemux

Alternatively, flvdemux could be altered to not require
seekability. I am unsure what is the best approach.
