webrtcbin: Enforce m-line restrictions when creating offer

First fail the offer creation if the mid of an existing offer doesn't
match a forced m-mline.

Then, for all newly added mlines, first look for a transceiver that
forces this m-line, then add a "floating" one, then the data channel.
And repeat this until we're out of transceivers.

webrtcbin: Split pad name from mline

The simple case where this breaks is if you add a
datachannel and want to add a new pad (a new media) after). Another
case where this is broken is if the order of the media is forced to
something different by the peer.

It's more simple to just split both things completely. In practice, the
pads will be named in the order in which they are allocated, so it
shouldn't change the current behaviour, just enable new ones.

construct the union of all possible output caps from all path srcpads.

codecs: vp9decoder: Make duplicate_picture() vfunc optional

The default implementation was required when superframe parsing
was handled by vp9decoder. For instance, if a superframe consists
of multiple frames with show_existing_frame header, it was vague
that which GstVp9Picture should consume GstVideoCodecFrame.

After 1.18 release, we introduced vp9parse element and
superframe should be handled by upstream vp9parse elemenet now.
So, we don't need to care about the superframe at vp9decoder class
level anymore. Simply, a frame corresponding to show_existing_frame
can be dropped if subclass doesn't implement duplicate_picture().

the whole surface, the mapped VAImage of the original memory is put in

codecparsers: Reimplement VP9 parser

Existing VP9 parser implementation doesn't provide information
required by other stateless decoding APIs (i.e., DXVA and NVDEC),
specifically loop filter and segmentation parameters might not exist
current frame. So parser needs to fill the information by using previously
parsed information.
We can update the gstvp9parser implementation so that it can provide
all information required by stateless decoding APIs with a huge API break,
or adding more ugly struct in it.
Instead doing as such, this commit introduce a new VP9 parser implementation.

* All variables will follow the specification as much as possible:

* Parser will fill all the required information for decoding frame

v4l2codecs: Fix holding of reference picture buffer

The picture buffer (V4L2 CAPTURE buffer) was being released immediatly

request is done, the picture buffer might still be used as a reference
and should not be reused for further decoding yet.

This change effectively bind the picture buffer lifetime to the request.
So that if the picture is never showned (decode only frame) or the request
queue is full before the buffer is displayed, the picture buffer will
remain alive.

doesn't clarify these interpretations. So VA users have to figure out

VAImageFormats are queried. There is another static map with the
different interpretations of the RGB32 formats, and compare them with

Vulkan, by default, provides a define that depends on the architecture,

architecture dependent .gir file, which then causes multilib

avwait: Don't reset time tracking when receiving the same segment again

This causes avwait to go back into "dropping" mode until audio and video
are synced again, which is unnecessary when the segment didn't actually
change.

nvcodec: nvsldec: Refactor graphics api resource handling

* Move GL context object to GstNVDecoder object, and remove
  duplicated handling of each codec decoder element
* Don't create GL context too early. We can create it only if
  we need to negotiate with downstream gl element.

Add @ prefix to enum-variant references in documentation

Found while working on GStreamer-rs documentation, some enums had this
bit of text pasted verbatim in the enum documentation rather than
attached to the enum-variant.  Fortunately it seems these in WebRTC and
D3D11 are the only ones matching the non-@-prefixed pattern:

    ^ \* GST_\w+:\s*\w+

rtmp2/connection: Separate inner from outer cancelling

The connection cancels itself when it is closed. To avoid the
cancellable passed to `gst_rtmp_connection_new` from being unexpectedly
cancelled, separate inner from outer cancellation by holding two
cancellables.

we will use arbitrary 25/1 framerate value.

d3d11decoder: Resurrect zero-copy for fixed-size DPB pool

Enable zero-copy if downstream proposed pool and therefore decoder
can know the amount of buffer required by downstream.
Otherwise decoder will copy when our DPB pool has no sufficient
buffers for later decoding operation.

d3d11decoder: Implement array-of-texture DPB again

Re-implementation of array-of-texture based on d3d11 memory pool.

Part-of: <https://gitlab.freedesktop.org/gstreamer/gst-plugins-bad/-/merge_requests/2097>

d3d11: Implement memory pool

Major changes:
* GstD3D11Allocator: This allocator is now device-independent object
  which can allocate GstD3D11Memory object for any GstD3D11Device.
  User can get this object via gst_allocator_find(GST_D3D11_MEMORY_NAME)
* GstD3D11PoolAllocator: A new allocator implementation for texture pool.
  From now on GstD3D11BufferPool will make use of this memory pool allocator
  to avoid frequent texture reallocation. That usually happens because
  of buffer copy (gst_buffer_make_writable for example)

In addition to that, GstD3D11BufferPool will provide GstBuffer with
GstVideoMeta, because CPU access to a GstD3D11Memory without GstVideoMeta
is almost impossible since GPU drivers needs padding for stride alignment.

va: postproc: Set one buffer in pools as minimum.

Because some elements, such as videorate check that minimum are
different of maximum number of buffers in the proposed pool, since
they might hold one or more buffers.

h2645parser: Catch overflows in AVC/HEVC NAL unit length calculations

Offset and size are stored as 32 bit guint and might overflow when
adding the nal_length_size, so let's avoid that.

For the size this would happen if the AVC/HEVC NAL unit size happens to
be stored in 4 bytes and is 4294967292 or higher, which is likely
corrupted data anyway.

For the offset this is something for the caller of these functions to
take care of but is unlikely to happen as it would require parsing on a
>4GB buffer.

Allowing these overflows causes all kinds of follow-up bugs in the
h2645parse elements, ranging from infinite loops and memory leaks to
potential memory corruptions.
