Since allocators keep an available memory queue to reuse, video format and usage hint are now persistant while allocator's memories are around. This patch adds _set_format() and _get_format() for both VA allocators. _set_format() validates if given format can be used or reused. If no allocated surface previously it creates a dummy one to fetch its offsets and strides. Updated info is returned to callee. GstVaPool uses _set_format() at config to verify the allocator capacity and to get the surfaces offsets and strides, which are going to be used by the video meta. Allocator extracted caps are compared with caps from config and if they have different strides or offsets, force_videometa is set. A new bufferpool method gst_va_pool_requires_video_meta() is added return the value of force_videometa. This value is checked in order to know if decoders need to copy the surface if downstream doesn't announce video meta support.
