There could be a case where:
1) you do a new set_caps after buffers have been processed.
2) ts_offset gets set to a different value, eg 0.
033333333
3) your pads get EOS, but the check dor that doesn't work
because you use ts_offset + a truncated value < segment.stop
4) so in the next collected, you end up comparing for example:
0.
9999999999 > 1., which is false and means you don't send EOS.
Also adds scale_round in two other places where it potentially could
have caused problems.

rtspsrc: fix race in state change to paused
When we go to paused, we first flush the connection and then send the pause
command. As a result of the flushing, the scheduled paused command can get
lost. Wait until the connection is completely flushed and the rtsp task is
waiting before issuing the paused or playing request.

qtdemux: handle SEGMENT query

v4l2: Optimize negotiation by removing the query filter
As cameras tend to have a quite specific set of capabilities (specific
framerates for each resolution), getting the peer caps filtered by our
probed caps can cause a big increase in the caps size which slows down
things quire a bit.
As for negotiation v4l2 iterates through the caps of the peer to find the
first intersection with the probed caps, getting the fully expanded
intersection of capabilities is not useful.
Using the same testcase as for bug #702632, adding this patch on top of
the patches suggested there speeds up getting the inital frame from
around ~14-15 seconds to around ~3-4 seconds.

qtdemux: Disable usage of allocation queries
This can only reliably work if demuxers have a
separate streaming thread per srcpad. This should be
done in a demuxer base class, which integrates parts
of multiqueue

Avoid skipping moov atoms for fragmented MP4 files.
bug #700505
Following a representation change that causes a resolution change,
the video decoder fails to decode correctly. Dashdemux detects the
representation change and pushes a new caps event and an
initialization segment (a new moov atom) to the downstream qtdemux,
but it doesn't handle this new moov yet, it will only parse the
first one it receives.
This commit changes qtdemux to accept a new moov in a dash bitstream
switching scenario.

qtdemux: send stream-start only once for each stream
Do not send stream start again when reconfiguring a pad for new caps.
