Seungha Yang 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.

* to be able to be shared among various elements. Caller can get native
* Direct3D11 handles via getter method.
* Basically Direct3D11 API doesn't require dedicated thread like that of
* OpenGL context, and ID3D11Device APIs are supposed to be thread-safe.
* But concurrent call for ID3D11DeviceContext and DXGI API are not allowed.
* To protect such object, callers need to make use of gst_d3d11_device_lock()
