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.

None of them are specific to the YASM assembler.

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.

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.

Restore alphabetical order in lists, break overly long lines, do some
prettyprinting, add some explanatory section comments, group parts
together that belong together logically.

That buffer is read only and marking it accordingly let
the user passing a constant buffer to it without having
a const-correctness warning.

Deprecated in 11/2012.

The .text section is already 16-byte aligned by default on all supported
platforms so `SECTION_TEXT` isn't any different from `SECTION .text`.

Fixes the corner case in which the internal buffer size
is larger than input buffer provided and resizing it
before moving the left over samples would make it write
to now unallocated memory.

This applies to every library where performance is not critical.

modelled after aarch64 code

on Cortex-A8, s16 and s32 code is about 2x faster,
float code about 7x faster

This treats mono as planar internally within libavresample rather
than changing the sample format.

Utility function to get the upper bound on the number of samples the
resampler would output.

Instead of setting FFLIBS in each library Makefile configure
exports FFLIBS-$library in config.mak.

Optimized for the default filter length 16.

30% faster opus silk decoding.

Required for arch optimized resampling.

This fixes cases where very few input samples (fewer than needed for one
output sample) are passed to lavr at the beginning.

This simplifies the code, since we do not have to deal with a possibly
negative source index anymore.

negative sample_index is handled in the block above.
