ef8d630a59 rtp: add H.261 RTP payloader and depayloader
Implementation according to RFC 4587.

Payloader create fragments on MB boundaries in order to match MTU size
the best it can. Some decoders/depayloaders in the wild are very strict
about receiving a continuous bit-stream (e.g. no no-op bits between
frames), so the payloader will shift the compressed bit-stream of a
frame to align with the last significant bit of the previous frame.

Depayloader does not try to be fancy in case of packet loss. It simply
drops all packets for a frame if there is a loss, keeping it simple.

5ae672fd22 rtpjitterbuffer: Consider timers len to compare with RTP_MAX_DROPOUT
When there are a lot of small gaps, we can consider that there is
a big gap (too losses) to reset the buffer.

3df0cce65d rtpjitterbuffer: If possible, always update the current time before looping over all timers
If we have a clock, update "now" now with the very latest running time we have.
If timers are unscheduled below we otherwise wouldn't update now (it's only updated
when timers expire), and also for the very first loop iteration now would otherwise
always be 0.

Also the time is used for the timeout functions, e.g. to calculate any times
for the next timeouts and we would otherwise pass too old times there.

8b0d11a0ee rtph263pay: Stop using an adapter and directly use the buffer
We always pushed one buffer into the adapter, then handled exactly that one
buffer and flushed it from the adapter. Now also don't memcpy() the actual
payload but just attach the input buffer's data to the output buffer.

This code still needs some serious refactoring/rewriting.

de5cd0995b Revert "rtpjitterbuffer: If we have an immediate timeout, don't try to find an earlier timeout"
This reverts commit 0c21cd7177.

If we have multiple immediate timers, we want to first handle the one with the
lowest sequence number... which would be broken now.

Instead of this we should just use a GSequence for the timers, and have them
sorted first by timestamp, and for equal timestamps by sequence number. Then
we would always only have to take the very first timer from the list and never
have to look at any others.

0c21cd7177 rtpjitterbuffer: If we have an immediate timeout, don't try to find an earlier timeout
If we have lots of such immediate timeouts, we would otherwise have quadratic
runtime in the number of timeouts.

0dcd76447a qtdemux: does not detect orientation
Most files don't contain the values for transposing the coordinates
back to the positive quadrant so qtdemux was ignoring the rotation
tag. To be able to properly handle those files qtdemux will also ignore
the transposing values to only detect the rotation using the values
abde from the transformation matrix:

[a b c]
[d e f]
[g h i]

2359ee29e8 qtmux: Correctly calculate the elst media start
The media start has nothing to do with the shift we have applied
but with the value of the first PTS. This is defined as:

  Dt(0) = 0
  Ct(0) = Dt(0) + CTTS(0)

So the media start is always the first CTTS.

eceb2ccc73 qtdemux: accumulate previous edts entries into segment.base
Allows playing edts editted files with proper synchronization of
streams. This patch fixes the regression introduced by
bf95f93c01 that was added to fix
segment seeks handling.

Having the accumulated_base separated from the main segment.base
allows handling both segment seeks and edts editted files.

1ec9a86e72 qtmux: store last_dts of the first buffer
Buffers need not to start at running-time 0 so the last_dts needs
to be the value of the first buffer's dts as it is used to compute
the duration of the buffers. If it was left at 0 the first buffer
would have a larger duration when it shouldn't

d61e5393f1 splitmuxsink: Mask async-start/done while switching files.
Sometimes, extra async-start/done from the internal sink
while the element is still starting up can cause splitmuxsink
to stall in PAUSED state when it has been set to PLAYING
by the app. Drop the child's async-start/done messages while
switching, so they don't cause state changes at the
splitmuxsink level.

dd72267a8d qtdemux: Add cslg support
The cslg atom provide information about the DTS shift. This is
needed in recent version of ctts atom where the offset can be
negative. When cslg is missing, we parse the CTTS table as proposed
in the spec to calculate these values.

In this implementation, we only need to know the shift. As GStreamer
cannot transport negative timestamps, we shift the timestamps forward
using that value and adapt the segment to compensate. This patch also
removes bogus offset of ctts_soffset, this offset shall be included
in the edit list.
