Changes 1.19.0:
- Support float and 32/24 bit integer output also with fixed-point decoders \ 
(conversion from 16 bit precision).
- A-Law output encoding is actually implemented now (Michael introduced the \ 
encoding back in the old days without ever implementing theconversion table, \ 
apparently).
- Added --with-cpu=arm_fpu as decoder choice for runtime switch between plain \ 
fpu code and NEON.
- Fix ARM builds to work properly on debian systems without special CFLAGS (NEON \ 
decoder, specifically).
- Make scripts/benchmark-cpu.pl check the return value instead of delivering \ 
crazy timings for crashed mpg123.
- Trigger track initialization in mpg123_info() to avoid use of uninitialized \ 
variables (watch out for MPG123_NEED_MORE return value!).
- Fix integer code to 32 bit numbers where it would waste 64 bit on modern systems.
- Add non-executable stack marking also to ARM assembly.
