Different VA drives might have different definitions for RGB32 color
formats because different bit interpretation. Sadly the specification
doesn't clarify these interpretations. So VA users have to figure out
what's the correct mapping with it's rendering color format
definition.
This patch aims to fix the static map structure after the
VAImageFormats are queried. There is another static map with the
different interpretations of the RGB32 formats, and compare them with
the given VAImageFormat, then with the GStreamer color format, update
the mapping table.
Finally, some RGB32 color formats were added.

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.

vapostproc tries to be in passthrough mode as much as possible. But
they might be situations where the user might force to process the
frames. For example, when upstream sets the crop meta and the user
wants VA do that cropping, rather than downstream.
For those situations this property will disable the passthrough mode,
if it's enabled.

If incoming buffers have crop meta it's done by vapostproc, iif
vapostproc is not in passthrough mode and downstream doesn't handle
it.
This patch announces the crop meta API in proposed bufferpool, while
it stops filtering meta APIs, since it was only filter crop api.
Also if downstream supports crop and video metas, vapostporoc
announces both meta APIs in upstream bufferpool.
Finally, the meta is removed from the buffer if the crop is enabled.

This new struct describes the input and output GstBuffers to
post-process, including VA flags. It also contains the VASurfaceID and
VARectangle, but those are private, completed inside GstVaFilter.
It is used for pass arguments to gst_va_filter_convert_surface() function.

When an input buffer needs to be copied into a VA memory, it's
required to create a buffer pool. This patch uses the
propose_allocation() caps to instantiate the allocator and pool,
instead of the negotiated caps, which rather represents the resolution
to display.

Derived images are direct maps to surfaces bits, but in Intel Gen7 to
Gen9, that memory is not cachable, thus reading can be very slow (it
might produce timeout is tests such as fluster).
This patch tries first to define if derived images are possible, and
later use them only if mapping is not for reading.

This plugin, for decoders more concretely, assumes that a VA config
can do certain color conversions when mapping frames onto CPU's
memory.
This assumption was valid for i965 and Gallium drivers which generates
valid outputs in bitstreams testers (v.gr. fluster). Nonetheless, iHD,
even when it generates acceptable rendered frames, output's MD5 of
tests weren't valid.
This patch append the image formats, for color conversion when mapping
to memory, for non-iHD drivers.

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.

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.

We've been doing retry with 1ms sleep if DecoderBeginFrame()
returned E_PENDING which means application should call
DecoderBeginFrame() again because GPU is busy.
The 1ms sleep() during retry would result in usually about 15ms delay
in reality because of bad clock precision on Windows.
To improve throughput performance, this commit will enable
high precision clock only for NVIDIA platform since
DecoderBeginFrame() call on the other GPU vendors seems to
succeed without retry.

After the VA filter creation, when changing the element's state from NULL
to READY, immediatly checks for any filter operation requested by the user.
If any, the passthrough mode is disabled early, so there's no need for a
future renegotiation.

When we transform the caps from the sink to src, or vice versa, the
"caps" passed to us may only contain parts of the features. Which
makes our vpp lose some feature in caps and get a negotiation error.
The correct way should be:
Cleaning the format and resolution of that caps, but adding all VA,
DMA features to it, making it a full feature caps. Then, clipping it
with the pad template.

For reverse playback, we are always copying decoded
frame to downstream buffer. So the pool size can be
and need to be large enough.
In case that forward playback, however, we need to restrict
the max pool size for performance reason. Otherwise decoder
will keep copying decoded texture to downstream buffer pool
if decoding is faster than downstream throughput
performance and also there are queue element between them.

Decoder might be able to copy decoded texture to the other buffer pool
during playback depending on context. In that case, copied one
has no D3D11_BIND_DECODER bind flag.
If we used ID3D11VideoProcessor previously for decoder texture,
and incoming texture supports ID3D11VideoProcessor as well even if it has no
D3D11_BIND_DECODER flag (having D3D11_BIND_RENDER_TARGET for example),
allow zero-copying instead of using our fallback texture.
Frequent conversion tool change (between ID3D11VideoProcessor and generic shader)
might result in inconsistent image quality.

... instead of QueryInterface-ing per elements. Note that
ID3D11VideoDevice and ID3D11VideoContext objects might not be available
if device doesn't support video interface.
So GstD3D11Device object will create those objects only when requested.
