627067118c avutil: Add av_timegm as a public function 
This is useful, since the normal timegm function isn't a standard
function (requiring _BSD_SOURCE or _SVID_SOURCE on glibc to
be visible, and not available on e.g. windows). The widely available
function mktime uses the local time zone, which requires ugly
workarounds to handle UTC time.

bb3244dee2 Replace all usage of strcasecmp/strncasecmp 
All current usages of it are incompatible with localization.
For example strcasecmp("i", "I") != 0 is possible, but would
break many of the places where it is used.

Instead use our own implementations that always treat the data
as ASCII.

2f7f2e4b41 Update x86inc.asm to latest x264 version, and add AVX symmetry. 
We keep INIT_AVX (for backwards compatibility). 3arg AVX ops with
a memory arg can only have it in src2, whereas SSE emulation of
3arg prefers to have it in src1 (i.e. the mov). So, if the op is
symmetric and the wrong one is memory, swap them.

299234a0a9 avoptions: Fix av_opt_flag_is_set 
With the changes in 3b3ea34655,
"Remove all uses of deprecated AVOptions API", av_opt_flag_is_set
was broken, since it now uses av_opt_find, which doesn't return
named constants unless a unit to look for the constant in is given.

This broke enabling LATM encapsulated AAC output in RTP.

641c7afe3c AVOptions: add new API for enumerating children.

AVFormatContext->AVIOContext->URLContext)

This will also allow the new setting/reading API to transparently apply
to children contexts.

This patch adds the possibility to calculate the DES-CBC-MAC of a
source buffer (i.e. the last block of the buffer encrypted in CBC
mode) without having to allocate a destination buffer that is as
long as the complete source buffer, but instead only 8 bytes
for the MAC.
