The code responsible for creating retransmitted buffers
assumed the stored buffer had been created with
rtp_buffer_new_allocate when copying the extension data,
which isn't necessarily the case, for example when
the rtp buffers come from a udpsrc.

Similar to the get-session and get-internal-session signals,
we expose a get-storage signal in addition to the
get-internal-storage signal to give access to the actual
element for applications that need to set properties on the
element, in particular "size-time"

With this the muxer is not set to NULL after each segment but instead
only flush events are sent to it to reset the EOS state.
As a result, the muxer will keep stream state and e.g. mpegtsmux will
keep the packet continuity counter continuous between segments as needed
by hlssink2.

The value stored in cenc_aux_sample_count wasn't in sync with the
parsing code that followed which checks whether all entries are
valid and present.
Only write the actual sample count when we know for sure.
CID #1427087
This exposes a new property, mtu, which is used to determine the
initial size of buffers from the buffer pool. If received data
exceeds this, the element gracefully handles that in a manner similar
to what we had previously: a large memory gets filled and reallocated
at the next call to "fill".
The default size is set to 1500, which should cover most use cases.

Optimize GstUdpSrc for cache performance.
Move the hot properties, which are used by the read function, to the top:
@used_socket, @addr, @cancellable, @skip_first_bytes, @timeout,
@retrieve_sender_address.
Remove the unused property @ttl.
Where needed reorder so that holes are avoided (the 64-bit @timeout)

The samples table is sorted by DTS, not PTS. As such we can only get the
correct result when using a binary search on it, if we search for the
DTS.
Also if we only ever search for the frame, where the following frame is
the first one with a PTS after the search position, we will generally
stop searching too early if frames are reordered.
In forwards playback this is not really a problem (after the decoder
reordered the frames, clipping is happening), in reverse playback
it means that we can output one or more frames too few as we stop too
early and the decoder would never receive it.

76e458a119 changed the conditions from
"queued > threshold" to "queued >= threshold", which broke hlssink2 and
resulting in too small fragments being created although keyframes would
be at *exactly* the configured threshold.

Fix compilation with MSVC. We still assume that attribute
is supported by all other relevant compilers, which seems
to be the case since we haven't had any complaints about
similar code in rtpsbcpay.
This works around a bug in various ONVIF cameras that implement the
attributes the wrong way around. They still won't work with a
backchannel but at least normal playback will work for the time being.
It restores pre-1.14 behaviour where we would fail to preroll on any SDP
that lists a recvonly stream. For 1.16 a better solution should be
found.
The problem here is that the ONVIF spec has the meaning of the two
attributes the wrong way around in the examples, compared to RFC4566.

As stated in commit c2956036b8 in -bad,
the wasapi elements are now better than directsound, and should be
preferred if they are available.
For a later release, once the elements have more testing, we can
consider moving them to -good.
Only up to timescale * G_MAXINT16 is possible as cluster duration, which
is already higher than our default value. Using higher values would
cause overflows and broken files.

Matroska does not support changing the stream type and stream properties
after the headers were started to be written, and for example H264
codec_data changes can't be supported.

rtpulpfeccommon.c:432:27: error: format ‘%lx’ expects argument of type
‘long unsigned int’, but argument 10 has type ‘guint64 {aka long long unsigned int}’

The ulpfecenc "mux-seq" and "ssrc" properties were initially added
because the element did more than implement ULPFEC. As it was
decided that FLEXFEC would be implemented in a separate element,
both properties are now unneeded and confusing.
Change the default for the ulpfecenc multi-packet property,
as it is expected that most users of this element will be protecting video
streams.
Change the default property for the rtpredenc allow-no-red-blocks
property, as it should also be its default mode of operation.

It is expected that when connecting to a stream that has
already started, the caps will only arrive at the interval
specified on rtpgstpay, we shouldn't be warning as this is
a normal mode of operation.
