  NVDEC: Fix handling of stream changes

- the NVDEC decoder would fail if the stream resolution increased
- as a workaroud, allocate our 'own' frames context - which for some
reason the decoder is happy to release at the correct times and the
decoder continues without issue
- as a side effect, we now need to treat nvdec like VAAPI and VDPAU
(which also use an allocated frames context) and release the pause frame
when seeking/flushing.
