Enable some more Werror and fix compiler warnings

- All servers are now Werror
- All bus_managers are now Werror
- All input_server add-ons are now Werror
- Some more things in bin/ are Werror

Only tested on x86_64, I'll let the buildbot test on x86_gcc2 and RISC-V

Fix wrap for AUDIO_INT

Floats don't have enough precision for all 32 bit integers. In
particular, near INT32_MAX their value is INT32_MAX + 1, which, when
converted back to int becomes INT32_MIN.

U8 sound format

U8 sound has a nonzero value as its zero amplitude, so it needs to be
special-cased when mixing, applying gains and other transformations.

Interpolating resampler: un-break it.

The interpolation was performed only on the samples in a buffer,
without "linking" with the previous one. This can't work.
* Remember the last sample from a buffer to be able to use it when
interpolating the first samples of the next one
* Adjust the kernel to properly loop over all samples in the buffer

Fixes #9438.

Mixer resampler: refactor using templates.

There is no need to copypaste the resampling code which is mostly the
same for all formats. However, gcc2 is confused by member function
templates (I hit an internal compiler error) so the resampling code was
moved to a static function instead.

* Fix one more off-by-one error in the interpolating resampler
* Since it now doesn't crash anymore; set it as default.

fix bugs in interpolating resampler :
* I got the downsampling version completely wrong. It should now be much better.
* A small bug in the delta calculation sometimes caused an off-by-one read to the source and a crash of the media add-on server

Effect of this resampler can be heard very clearly using the following setup in Cortex :
* Demo Audio producer producing a sinewave at any frequency (sampling rate is hardcoded at 44100Hz)
* Audio output set to 48000 Hz
* system mixer in between
select either resampler in the mixer and you'll hear the difference immediately.

Should finally fix #1351.

* Add a resampler that interpolates instead of dropping/copying samples.
* Not plugged anywhere yet.
* I'm not sure the downsampling is done properly, either.
