FSF addresses used in PA sources are no longer valid and rpmlint
generates numerous warnings during packaging because of this.
This patch changes all FSF addresses to FSF web page according to
the GPL how-to: https://www.gnu.org/licenses/gpl-howto.en.html
Done automatically by sed-ing through sources.

Because debian does not run with the freebsd libc, but rather uses the
GNU one, it chose to not define __FreeBSD__, but rather __FreeBSD_kernel__.
Use the alternative when the functionality tested is for kernel
features, and keep the __FreeBSD__ one when using freebsd libc
headers.
If this patch is applied, debian could drop all the current patches when
importing 6.0 :)

for example, the conversion function for
convert_from_float32ne(PA_SAMPLE_S16LE) can also be used for
convert_to_s16ne(PA_SAMPLE_FLOAT32LE)
v2: ARM can potentially be big- or little endian; only apply
optimization on LE based on WORDS_BIGENDIAN #define (thanks, Tanu)

Don't try to compile this code on 32-bit FreeBSD, it will error out complain
about registers only being available in 64-bit mode.

use (1<<15) instead of 0x7fff as a factor when converting from s16 to float32
use (1<<31) instead of 0x7fffffff as a factor when converting from s32 to float32
the change is motivated by the following desireable properties:
* s16_from_f32(f32_from_s16(x)) == x for all possible s16 values
* x / (1.0f << 15) == x * (1.0f / (1 << 15)) for all x in s16
above changes enable easier optimization while guaranteeing bit-exact results
further, other audio sample conversion code (libavresample) does it the same way
v3 (comments Tanu):
* fix saturation in pa_sconv_s16le_from_f32ne_neon(), use vqrshrn
v2 (comments Tanu):
* fix comments in ARM NEON code
* use llrintf() in pa_sconv_s32le_from_float32ne()

It tests only x86 architecture right now.

the random floats x should be zero-mean with -(1+eps)<x<(1+eps) for some
small epsilon; previously only negative x were generated

Make assembly syntax compatible to the X32 toolchain and fix the
following kind of compilations errors with X32 gcc.

Originally these assembly lines were written for x86_64 ABI, now they
are also compatible with X32 ABI [3][4].
The patch was submitted to the OpenEmbedded-Core list [1][2].

Use #include "header.h" if functionality of header.h is implemented
and #include <header.h> if functionality of header.h is used.

Only whitespace changes in here

At least on 32bit compiles, there are not enough registers.
