Use AVCodecContext.compression_level rather than a private option,
replacing the H.264-specific quality option (which stays only for
compatibility).
This now works with the H.265 encoder in the i965 driver, as well as
the existing cases with the H.264 encoder.
(cherry picked from commit 19388a7200)
Without this its possible to make the new decode API decode billions of samples
out of a empty input and never return to the caller before all samples have been
created and discarded.

Using named define properly documents the code paths.
It also avoids passing additional numbered arguments through
multiple levels of macro templates.
The suffix handling is done by concatenation, like in
other asm functions and avoid having two separate
"cglobal" defines.

This splits the asm function into exact and non-exact version. The exact
version is as fast or faster on newer CPUs (which EXTERNAL_AVX_FAST describes
well) whilst the non-exact version is faster than the exact on older CPUs.
Also fixes yasm compilation which doesn't accept !cpuflags(avx) syntax.
