b9e51facdd d3d11decoder: Fix potential use after free
A DPB buffer held by codec picture object may not be writable
at the moment, then gst_buffer_make_writable() will unref passed buffer.

Specifically, the use after free or double free can happen if:
* Crop meta of buffer copy is required because of non-zero
  top-left crop position
* zero-copy is possible with crop meta
* A picture was duplicated, interlaced h264 stream for example

Interlaced h264 stream with non-zero top-left crop position
is not very common but it's possible configuration in theory.

Thus gst_buffer_make_writable() should be called with
GstVideoCodecFrame.output_buffer directly.

a7353d8859 d3d11decoder: Fix crash on negotiate() when decoder is not configured
The negotiate() can be called by GstVideoDecoder baseclass on GAP event,
and decoder helper object might not be configured at the time
when negotiate() is called.

8325623051 d3d11decoder: Reduce DPB size
Now all codec baseclasses can inform subclasses of correct max DPB size,
and exception handling (e.g., emergency bumping in h.264) has been
improved as well. Smaller number of additional DPB frame allocation
seems to be safe.

2e574a80d9 d3d11: Don't use g_alloca()
_alloca CRT function is deprecated. Moreover, stack allocation
for string is not a good idea. We can use _malloca inline
function instead, but all use of _alloca in d3d11 library/plugin
are not performance critical path at all.

170271b86f d3d11: Revert staging buffer pool implementation
The staging buffer pool implementation was added to improve
throughput performance since we can avoid per-frame
CPU copy operation via staging texture but it turned out that
we can not make it thread safe. See
https://gitlab.freedesktop.org/gstreamer/gstreamer/-/issues/1182

e1fd0f620f d3d11decoder: Add support for non-zero crop-{x,y} position
AVC and HEVC define crop rectangle and the x/y coordinates might

via GstVideoCropMeta if downstream supports the meta and d3d11 memory.
Otherwise decoder will copy decoded texture into output frame.

NVIDIA GPUs have undocumented limitation regarding minimum resolution

bring CUDA/NVDEC API into D3D11, use hardcoded values for now
until we find a nice way for capability check.

5707e487cf d3d11: d3d11decoder: Use DXGI adapter LUID
... instead of index of DXGI adapter.

The order of IDXGIAdapter1 enumerated via IDXGIFactory1::EnumAdapters1
can be varying even there's no rebooting in case that GPU preference order
is updated by user (for example, it can be done by using NVIDIA Control Panel
in case of multi-GPU laptop system) and eGPU is another possible case.

So, for an element which requires fixed target GPU requirement,
index based device enumeration is unreliable.
