vtdec: handle non-consecutive GstBuffer input without copying
This patch implements non-contiguous CMBlockBuffers.
In the process, I've realised we were using CMBlockBufferCreateWithMemoryBlock
improperly. It does NOT copy its input buffer, so gst_buffer_unmap-ing
immediately is incorrect. In the new implementation, its the CMBlockBuffer's
responsibility to unmap.
P.S. Once bug 747707 lands, I think cm_block_buffer_from_gst_buffer should move
into the library.
