640a65bf96 gst: don't use volatile to mean atomic
volatile is not sufficient to provide atomic guarantees and real atomics
should be used instead.  GCC 11 has started warning about using volatile
with atomic operations.

824b0ce0f4 Revert "d3d11: Enable native multi-thread protection layer and make use of it"
This reverts commit 872b7f503c.

Native multi-thread protection layer seems to be consuming more CPU
resource than application side protection approach in some cases

872b7f503c d3d11: Enable native multi-thread protection layer and make use of it
... instead of our own GRecMutex locking. In this way, any other
Direct3D11 client (MediaFoundation for example) can safely call
any Direct3D11 API even when we are sharing our Direct3D11 device
with others.

615f52f2f7 d3d11device: Hold ID3D11VideoDevice and ID3D11VideoContext object
... 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.

5b3e316039 d3d11: Port to C++
Direct3D11 objects are COM, and most COM C APIs are verbose
(C++ is a little better). So, by using C++ APIs, we can make code
shorter and more readable.
Moreover, "ComPtr" helper class (which is C++ only) can be
utilized, that is very helpful for avoiding error-prone COM refcounting
issue/leak.

cfbc580575 d3d11: Add support for deinterlacing by using ID3D11VideoProcessor interface
Add a new element d3d11deinterlace to support deinterlacing.
Similar to d3d11videosink and d3d11compositor, this element is
a wrapper bin of set of child elements including helpful
conversion elements (upload/download and color convert)
to make this element configurable between non-d3d11 elements.
