The position of the second MV predicitor candidate is slightly different
for the old WMV3 format indicated by RES_RTM_FLAG. This patch fixes
decoding of niceday.wmv on the samples server.

The B predictor for 4-MV macroblocks is only out of bounds when
the A predictor is also out of bounds.

this was a typo in my original dst decoder. there is no requirement for
64-byte alignment here. the change does not affect decoder performance.

Add VDENC(lowpower mode) support for QSV H264
It's an experimental function(like lowpower in vaapi) with
some limitations:
- CBR/VBR require HuC which should be explicitly loaded via i915
module parameter(i915.enable_guc=2 for linux kernel version >= 4.16)
Use option "-low_power 1" to enable VDENC.
Add in dump_video_param() to show the status of VDENC in runtime log.

Dav1dPictures contain more than one buffer reference, so we're forced to use the
API properly to free them all.

Some of the assembly functions e.g. ff_h264_idct_dc_add_neon
has code like:
movrel x14, X(ff_h264_idct_add_neon)
Linker cannot resolve them fully at link time and emits dynamic
relocations.
Use explicit labels instead so that no dynamic relocations are
needed at all.
This avoids lld complains about text relocations.
