lavf/udp: fix dead code.

Since d607861, service can not be NULL, only "0".
An UDP address with neither local port nor address leaves both
service and node to their default value, and POSIX specifies
that they are not allowed to be both NULL; "0" is equivalent
to an unspecified port for all currently known protocols.

Fix CID 1341570.

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.
