Major changes: * GstD3D11Allocator: This allocator is now device-independent object which can allocate GstD3D11Memory object for any GstD3D11Device. User can get this object via gst_allocator_find(GST_D3D11_MEMORY_NAME) * GstD3D11PoolAllocator: A new allocator implementation for texture pool. From now on GstD3D11BufferPool will make use of this memory pool allocator to avoid frequent texture reallocation. That usually happens because of buffer copy (gst_buffer_make_writable for example) In addition to that, GstD3D11BufferPool will provide GstBuffer with GstVideoMeta, because CPU access to a GstD3D11Memory without GstVideoMeta is almost impossible since GPU drivers needs padding for stride alignment.
