a75e88fdd2 d3d11memory: Remove unnecessary locking
* memory map/unmap is already protected by d3d11 device lock.
  Don't need to take another memory lock.
* Use WIN32 critical section and slim reader/writer lock APIs
  directly instead of GLib wrappers.

21e5c33797 d3d11memory: Allow null GstD3D11Allocator to alloc methods
Similar to gst_allocator_alloc(), use default GstD3D11Allocator
when caller passes null allocator object

74f56632c3 d3d11: Use std::call_once()
g_once_init_enter() always takes global mutex for non-GCC build.
Use C++ once call implementation

32eeadb4a5 d3d11: Define enum and flags types manually
gnome.mkenums_simple() doesn't work well for GstD3D11, seems to
be confused by numeric representation of D3D11, must be a bug
in GLib or so. Just don't rely on the incomplete automagic.

347ad181be d3d11memory: Update alloc_wrapped() API to avoid staging texture alloc
Add size parameter and use it for CPU accessible memory size
instead of allocating staging texture per API call.

46a3394581 d3d11memory: Add private method for texture wrapped memory allocation
Unlike public method gst_d3d11_allocator_alloc_wrapped(), newly
added method by this commit will not calculate CPU accessible memory
size, since staging texture must be allocated to calculate the size.

application texture using GstD3D11Memory without copy.

fce7431381 d3d11: Install library headers
Our Direct3D11 abstraction layer has been improved and
it gained good shape from API point of view.
Also, On Windows, GstD3D11 has various advantages over GstGL
in terms of compatibility/stability/feature/performance.
Note that WGL implementation is known to be buggy for some
drivers/vendors/scenario (that's a reason why Google implemented ANGLE).
Moreover, GstGL is not fully optimized for Windows unfortunately.

It's the time to open this interface to application developers
for various optimized processing using our Direct3D11
infrastructure.

fe64295841 d3d11decoder: Work around Intel DXVA driver crash
Intel DXVA driver crashes sometimes (from GPU thread) if
ID3D11VideoDecoder is released while there are outstanding view objects.
To make sure the object life cycle, holds an ID3D11VideoDecoder refcount
in GstD3D11Memory object.

0deb73d9ba d3d11memory: Clear YUV texture with black color
We prefer black color as an initial texture color and
Direct3D11 runtime will initialize texture with zeros (except for alpha)
which is fine for RGB formats. But UV components of YUV texture
requires manual clear for black color.

47ff41bcd2 d3d11memory: Protect against concurrent access from GPU and CPU to staging texture
Staging texture does not allow GPU access while it's CPU mapped.
But because we cannot block concurrent READ access by GstMemory design,
additional staging texture is still required.
