gst_caps_new_simple gets wrong types for rate and channel which
may lead to a crash.
As 64-bit values for rate, depth, format, channels does not
make much sense and since any other functionality in gstreamer
expects G_TYPE_INT for channels and rate, we should stick to that

This (so-far) Linux- and FreeBSD-only API lets users create file
descriptors purely in memory, without any backing file on the filesystem
and the race condition which could ensue when unlink()ing it.
It also allows seals to be placed on the file, ensuring to every other
process that we won’t be allowed to shrink the contents, potentially
causing a SIGBUS when they try reading it.
This patch is best viewed with the -w option of git log -p.
It is an almost exact copy of Wayland commit

Adding vp9parse element to parse various stream information such as
resolution, profile, and so on. If upstream does not provide resolution and/or
profile, this would be useful for decodebin pipeline for autoplugging
suitable decoder element depending on template caps of each decoder element.
In addition, vp9parse element supports unpacking superframe into
single frame for decoders. The vp9 superframe is a frame which consists
of multiple frames (or superframe with one frame is allowed) followed by superframe
index block. Then unpacked each frame will be considered as normal frame
by decoder. The decision for unpacking will be done by downstream element's
"alignment" caps field, which can be "super-frame" or "frame".
If downstream specifies the "alignment" as "frame",
then vp9parse element will split an incoming superframe into single frames
and the superframe index (located at the end of the superframe) data
will be discarded by vp9parse element.

The default BYTE DURATION basesrc query handler will return `-1` and TRUE. In
order to properly handle cases where upstream http servers didn't return a valid
Content-Length we also need to check whether it was valid when calculating
bitrates.
Avoids returning completely bogus bitrates with gogol's video streaming services

Add custom IMFMediaBuffer and IMF2DBuffer implementation in order to
keep track of lifecycle of Media Foundation memory object.
By this new implementation, we can pass raw memory of upstream buffer
to Media Foundation without copy.

Making the thread receiving the stats wait on the loop to respond was
not a good idea, as the latter can get blocked on the streaming thread.
Have get_stats read the values directly, adding a lock to ensure we
don't read garbage.

Ensure we take the object lock while accessing `GstElement.sinkpads`.
Use an iterator when the code isn't simple to avoid deadlock.
When we find the best pad, take a reference so a concurrent pad
release doesn't destroy the pad before we're done with it.

There are quite a few reserved PID in the various MPEG-TS (and derivate)
specifications which we should definitely not use. Those PID have a certain
meaning and purpose.
Furthermore, a lot of the code in the muxer implementation also makes assumption
on the purpose of streams based on their PID.
Therefore, when requesting a pad with a specific PID, make sure it is not a
restricted PID.
