Blackfin is a painful platform to work with, no test machines are available
and the range of multimedia applications is dubious. Thus it only represents
a maintenance burden.

Also shorten HuffYUV context member names to avoid clutter.

Also shorten HuffYUV context member names to avoid clutter.

This avoids recalculating the value over and over again.

Also switch from "tbl" to "tab" name suffixes.

The function is supposed to confirm that the compiler provided enough
alignment, but in practice it is only run in certain code paths and
insufficient alignment problems are restricted to legacy compilers.

SPARC is no longer being used in any multimedia-related fields and the
VIS optimizations only represent a maintenance burden.

SH4 has been end-of-lifed and no more test machines are available.

This also fixes masking the bits

The (optimized) functions are used nowhere else.

Alpha has been end-of-lifed and no more test machines are available.

Also give consistent names to init functions.

dct_bits is never set except in h264, where it is never used,
thus remove it.

dsputil_init() is deprecated and not meant to be exported.
ff_dsputil_init() is internal to libavcodec and thus can not be used.
avpriv_dsputil_init() is the version shared between libraries.

This commit fixes 3 unjustified libavfilter deprecated warnings.
