4f45828641 d3d11: Get rid of "extern "C"" wrapping for GST_DEBUG_CATEGORY_EXTERN 
Instead, change the file defining debug category to cpp

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.
