Alexandra Hájková ffa190d047 Move VLC and RL_VLC_ELEM structure definitions to a separate header 
Use the newly created vlc.h directly instead of including get_bits when needed.
The VLC and RL_VLC_ELEM structures are independent from the bitreader.

Ganesh Ajjanagadde e11e32686f avcodec/bitstream: replace qsort with AV_QSORT 
Commit 3a0a2f33a6 claims large performance
advantages for AV_QSORT over libc's qsort. The reason is that I suspect
that libc's qsort (at least on non LTO builds, like the typical FFmpeg config)
can't inline the comparison callback:
https://stackoverflow.com/questions/5290695/is-there-any-way-a-c-c-compiler-can-inline-a-c-callback-function.
AV_QSORT has two things going for it:
1. The guaranteed inlining of qsort itself. This yields a negligible
boost that may be ignored.
2. The more serious possibility of potentially allowing the comparison
function to be inlined - this is likely responsible for the large boosts
reported.

There is a comment explaining that this is a place that could use some
performance improvement. Thus AV_QSORT is used to achieve that.

Benchmarks deemed unnecessary due to existing claims about AV_QSORT.
Tested with FATE.
