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 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.

macros for reading and writing 64-bit aligned little-endian values.
these macros are used by the DST decoder and give a performance boost
on platforms that where the compiler must guard against unaligned
memory access.
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.

DXVA2 may be enabled even when every relevant module is disabled,
which would result in the dependency generator not including its
extralibs to avcodec.
