b8426b865e avcodec: Document where the AVOption names can be found for the fields of AVCodecContext 
Missing docs found by: nevcairiel

RFC: should we add support so that the C field names always work as av option names/keys ?

785038c92c lavu: Adding ARIB STD-B67 (hybrid log-gamma) enum value and transfer function. 
Adding hybrid log-gamma (https://en.wikipedia.org/wiki/Hybrid_Log-Gamma)
based on the standardization in ARIB STD-B67:
http://www.arib.or.jp/english/html/overview/doc/2-STD-B67v1_0.pdf

The choice of enum value of 18 is consistent with HEVC:
http://phenix.it-sudparis.eu/jct/doc_end_user/current_document.php?id=10481

And also with latest proposal for color format in mkv:
https://mailarchive.ietf.org/arch/search/?email_list=cellar&gbt=1&q=Colour+Format+proposal

The implementation assumes a nominal input range of [0, 1], which is
consistent with HEVC.

d1f558b362 avcodec/dca: require checked bitstream reader 
Remove half-working attempt at supporting unchecked bitstream reader by
always copying input data into intermediate buffer with large amount of
padding at the end.

Convert LBR decoder to checked bitstream reader. Convert
dcadec_decode_frame() to parse input data directly if possible.
