Because we introduce the new va lib, the va examples need to include

e0915ce982 libs: va: Move the VA common logic as a lib.
The VA acceleration now has more usages in linux-like platforms,
such as the MSDK. The different plugins based on the VA acceleration
need to share some common logic and types. We now move the display
related functions and types into a common va lib.

4900e3583a codecs: gstvp9statefulparser: do not carry over segmentation flags
Do not carry over segmentation flags from previous frames. The spec
says in 7.2.10 that the feature data carry over from previous frames
if not updated, but the flags do not.

Consider what would happen if a flag B is to depend on a flag A, and
B carries over as set from another frame. Further consider that A is
now not set in this particular frame. This leads to the invalid state
in which flag B is set but flag A isn't.

This might cause the bitstream to be rejected by accelerators down
the line.

Fix it.

f7a341a1f0 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().

c36190cbda 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.

What is different from existing one?
* All variables will follow the specification as much as possible:
  VP9 Bitstream & Decoding Process Specification - v0.6 31st March 2016
* Parser will fill all the required information for decoding frame
  to GstVp9FrameHeader struct. In case of old VP9 parser,
  user needs to read additional data from parser's member variables.
* GstVp9StatefulParser object struct is completely completely opaque

cefdd0d0f1 vulkan: provide a custom VK_DEFINE_NON_DISPATCHABLE_HANDLE
If the application did not define one yet, define our own
VK_DEFINE_NON_DISPATCHABLE_HANDLE that is independent of the
architecture.

Vulkan, by default, provides a define that depends on the architecture,
which causes the symbol type to be different. This causes an
architecture dependent .gir file, which then causes multilib
installation problems because the .gir files can't be shared.

Make it possible to override the format specifier and provide
a default one that is compatible with the default non dispatchable
handle.

Return VK_NULL_HANDLE from functions that return a non-dispatchable
handle.

39b9f79e11 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.

ffa4d84e54 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.

a74651ddc1 play: Introducing the new playback library
This aims to be a replacement for the GstPlayer library. In GstPlay, notifications are
sent as application messages through a dedicated GstBus. The GMainContext-based
signal dispatcher was replaced by a GObject signal adapter, now relying on the
bus to emit its signals. The signal dispatcher is now optional and fully
decoupled from the GstPlay object.

636a77a83f codecs: mpeg2decoder: Move frame_unref to handle_frame.
In the current code, we call frame_unref only when the frame is
outputted. This is OK for normal playback, but when seek happens,
the frames stored in DPB is not outputted and causes some memory
leak.
The correct way is that we should call frame_unref every time we
finish the handle_frame(), which is also the behaviour of H264/H265
decoder.
