vaapi_encode: Check packed header capabilities
...
This improves behaviour with drivers which do not support packed
headers, such as AMD VCE on mesa/gallium.

vaapi_encode: Refactor initialisation
...
This allows better checking of capabilities and will make it easier
to add more functionality later.
It also commonises some duplicated code around rate control setup
and adds more comments explaining the internals.

vaapi_h264: Fix HRD bit_rate/cpb_size scaling
...
There should be an extra offset of 6 on bit_rate_scale and of 4 on
cpb_size_scale which were not accounted for here.

h264: add H264_ prefix to the NAL unit types
...
This will prevent conflicts e.g. in code that deals with both h264 and
hevc.

h264: create a new header for common h264 definitions
...
Move the NAL unit types into it. This will allow to stop including the
whole decoder-specific h264dec.h in some code that is unrelated to the
decoder and only needs some enum values.

h264: rename h264.[ch] to h264dec.[ch]
...
This is more consistent with the naming of other decoders.

targetting bitrate. Also adds NAL HRD parameters to VUI.

vaapi_h264: Add trivial support for low-power encoding
...
Experimental; requires Skylake and VAAPI 0.39.1 (not yet released).
Also increases the allowed range of the quality option - in low-power
mode, the Intel driver supports levels 1-8 (and 0 meaning default).

vaapi_h264: Fix frame_num after non-reference frames
...
Non-reference frames (nal_ref_idc == 0) should be discardable, so
frame_num does not advance after them. Before this change, a stream
containing unreferenced B-frames would be rejected by the reference
decoder.
