The YUV channels of VP6 are encoded in a highly linear fashion which does
not have any slice-like concept to thread. The alpha channel of VP6A is
fairly independent of the YUV and comprises 40% of the work. This patch
uses the THREAD_SLICE capability to split the YUV and A decodes into
separate threads.
Two bugs are fixed by splitting YUV and alpha state:
- qscale_table from VP6A decode was for alpha channel instead of YUV
- alpha channel filtering settings were overwritten by YUV header parse

Makes golden_frame more like other frame data, paves way for threading

In vp6 Advanced Profile, deblock filtering is conditionally enabled in
each frame header. In Simple Profile it should always be off. vp6 was
inheriting the wrong default from ff_vp56_init.

Also break some long lines, remove codec function placeholder comments

(cherry picked from commit d36beb3f69)
Create a custom table for VP5/6/8's renorm to avoid depending on H.264's.
Saves one instruction in the arithmetic decoder as well.

Using macro templates allows the vp[56]_adjust functions to be
inlined instead of called through function pointers. The new
function pointers enable optimised implementations of the filters.
4% faster VP6 decoding on Cortex-A8.

Passing an explicit filename to this command is only necessary if the
documentation in the @file block refers to a file different from the
one the block resides in.

Otherwise doxygen complains about ambiguous filenames when files exist
under the same name in different subdirectories.

Previous code worked by pure luck with glibc qsort implementation.
