This disables everything that was deprecated at least 18 months ago.

Readjust the minimum API version as needed, postponing any
API-incompatible changes until the next bump.

Also do some small cosmetic changes: Drop pointless _MMX suffix from ABSD2
macro name, drop pointless check for MMX support, we always assume MMX is
available in our SIMD code, fix spelling.

None of them are specific to the YASM assembler.

libswscale/swscale-test.c:369:20: warning: passing argument 2 of ‘sws_scale’ from incompatible pointer type [-Wincompatible-pointer-types]
libswscale/swscale.h:207:5: note: expected ‘const uint8_t * const* {aka const unsigned char * const*}’ but argument is of type ‘uint8_t ** {aka unsigned char **}’

This moves work from the configure to the Make stage where it can
be parallelized and ensures that pkgconfig files are updated when
library versions change.

Bug-Id: 449

Also move #includes into canonical order where appropriate.

It is used to select functions that work with 9-15bits.

Make sure the scaling functions for the 9-15bits are used for
9-15bits bit depths correctly.

Follow a 420, 422, 444 order instead of a random one.
This simplifies double-checking additions of new formats.

Split version files into one line per symbol/directive to allow compatibility
with the Solaris linker without preprocessing and eliminate $ from version file
templates to simplify the postprocessing shell command.

These warnings conflict with system macros on Solaris, producing
truckloads of warnings about macro redefinition.

together that belong together logically.
