This series contains fixes and improvements for the hantro H264 decoder.

Patch 1 and 5 fixes the motion vector buffer offset calculation for field encoded
and monochrome content and makes it possible to decode a sample from [1].

Patch 2 removes overallocation for the motion vector buffer,
only half of the extra size is needed.

Patch 3 changes to use the same source for width and height as is used for
motion vector buffer offset calculation.

The RFC patches that added bits to handle field encoded content have
been dropped and will be resent in a separate series.

The following sample from [1] is now playable with this series
- H264_1080i-25-interlace_Kaesescheibchen.mkv

This series has been tested using ffmpeg v4l2 request hwaccel at [2]

[1] http://kwiboo.libreelec.tv/test/samples/
[2] https://github.com/Kwiboo/FFmpeg/compare/4.0.4-Leia-18.4...v4l2-request-hwaccel-4.0.4-hantro

Changes in v3:
  - rebased on for-v5.5q
  - drop RFC patches
  - src_fmt instead of dst_fmt is used for width/height
  - address feedback from Boris

Changes in v2:
  - scaling list changes split to its own series
  - address feedback from Philipp and Ezequiel

Regards,
Jonas
