Paul B Mahol 3bef108fa9 libswresample/swresample: avoid s16p internal transfer format ...

Instead use float one by default for sample rate conversions.
The s16p internal transfer format produces visible and hearable
quantization artifacts.

for S8 we continue to use S16 as it should have enough precision
Fate is adjusted so bitexactness is maintained between mips/arm/x86
if more tests became bit-inexact on some platform, the same change
can be done to them

The use of higher precision and float intermediates inevitably
leads to more differences between platforms.
