Make sure we provide 128bit-aligned buffers to ffmpeg.

    Make sure we provide ffmpeg with 128bit-aligned data.

    Add a new function new_aligned_buffer() which creates a GstBuffer of
    the requested size/caps, with the memory being allocated/freed by ffmpeg's
    av_malloc/av_free which guarantees properly aligned memory.
    Added a can_allocate_aligned internal property which we use to figure out
    whether downstream can provide us with 128bit aligned buffers.
