f1b3ed37c6 gstrtpbasepayloader: Add property for scaling RTP timestamp
This patch introduces a property which, if set to FALSE, prevents RTP
basepayloader from scaling the RTP time when a segment's rate is not
equal to 1.0. The specification is ambiguous on this subject and some
clients expect the timestamps not to be scaled.

85e201fe30 rtpbasepayload: add property for embedding twcc sequencenumbers
By setting the extension-ID for TWCC (Transport Wide Congestion Control),
the payloader will embed sequencenumbers as a RTP header-extension
according to https://tools.ietf.org/html/draft-holmer-rmcat-transport-wide-cc-extensions-01#section-2

The negotiation of this being enabled with downstream elements
is done with caps reflecting the way this is communicated using SDP.

4152b0c840 rtpbasepayload: timestamp bug, if rate control=no
With commit "basepayload: Expose onvif-no-rate-control property" the rtp
timestamp changed behaviour when rate control is disabled.

When disabling rate control, we must take care of the stream time to
avoid the timestamps to begin from zero again.

f7408f9418 rtpbasepayload: don't use GINT_TO_POINTER with GType
GType can (and will) be 64bit. GINT_TO_POINTER is not.
This will result in the api-type checked for being a different one than
it actually is...

3c4bef46b7 basepayload: Expose onvif-no-rate-control property
The ONVIF spec mandates that when Rate-Control=no, the RTP timestamps
match the original sampling times, as opposed to the intended playback
time.

1eb9c5b309 rtpbasepayload: print list size in log output instead of -1
It is weird to see "Preparing to push packet with size 4294967295" in
the logs, so print the list length in case of a buffer list.

f766b85b96 rtpbasepayload: rtpbasedepayload: Add source-info property
Add a source-info property that will read/write meta to the buffers
about RTP source information. The GstRTPSourceMeta can be used to
transport information about the origin of a buffer, e.g. the sources
that is included in a mixed audio buffer.

A new function gst_rtp_base_payload_allocate_output_buffer() is added
for payloaders to use to allocate the output RTP buffer with the correct
number of CSRCs according to the meta and fill it.

RTPSourceMeta does not make sense on RTP buffers since the information
is in the RTP header. So the payloader will strip the meta from the
output buffer.

3113e341ea rtpbasepayload: Always prefer downstream's ssrc suggestion if any
Otherwise ssrc changes via rtpsession's (deprecated!) internal-ssrc property
are not possible anymore. rtpsession was now patched to only suggest an ssrc
if it makes sense to do so.

In 2.0 we should get rid of all the properties that are also negotiated via
caps, the code and behaviour is too confusing otherwise.

faafaaec56 rtpbasepayload: Try harder to reuse previously configured caps values and give more preference to anything set as properties
This affects the pt, ssrc, seqnum-offset and timestamp-offset properties. If
they were set from a property, or we configured caps before, we try to use
that value for them. Even if the first structure of the downstream caps
specifies a different value, we check if the value is supported by other
structures.
Only if all this fails, we use the values given by downstream in the first
structure, i.e. if no properties were set and these are the first caps we
negotiate or downstream does not support our values.

By doing this we ensure that we don't spuriously change ssrcs or other fields
in the middle of the stream (and also consider property values more). Ssrc
changes would currently happen after sending an RTX packet (thus creating a
new internal source inside the rtpsession), and then renegotiating the
payloader (which then gets the RTX ssrc from rtpsession).

d6dc1b6c46 rtpbasepayload: Let caps event also configure seqnum-offset
Previously the sequence number kept track of by GstRTPBasePayload would
only be set when going from READY to PAUSED state. This meant that a
downstream element that attempted to configure a basepayloader by
setting seqnum-offset e.g. in its sinkpad's caps template would have
trouble configuring the basepayloader. The reason was that the caps
event which arrives with the desired value for seqnum-offset did not
arrive at the basepayloader until caps negotiation took place,
significantly later than the transition from READY to PAUSED.

The result after this patch is that the default value for the
seqnum-offset property, or later set values for this property, will take
effect when going from READY to PAUSED like before. In addition the an
arriving caps event will also affect the basepayloaders configured
sequence number as the event arrives.

21c61586ad rtpbasepayload: error out if no CAPS event was received before buffers
Most payloaders set/send their own output format from the setcaps
function, so if we don't get input caps, things probably wont' work
right, even if the input format is fixed (as in the case of the mpeg-ts
payloader for example).

11a494d5c9 rtp: Add support for multiple memory blocks in RTP
Add support RTP buffers with multiple memory blocks. We allow one block for the

padding.
Remove the validate function, we validate now when we map because we need to
parse things in order to map multiple memory blocks.
