Patrick Pelissier 68c737dcef Clean up interface if (internal) genint: 
it returns at most an 2048, so an unsigned int is more enought
(and internally it was already used!).
So transform the interface to take as input unsigned int.

Fix maximum size supported by the genint package.

Add proper constant used for error, and use it in the code.

Patrick Pelissier f2b2335080 Fix issue with C++ not supporting passing an int constant value to an unsigned atomic type...

Patrick Pelissier 2c695526dd Fix issue with stricter C++ compiler with atomic definition.

Patrick Pelissier 1930bdeac1 _DEF macros checks if a global oplist is register if there is no one

Patrick Pelissier 72c5c3f371 Replace stdatomic.h (C11 standard compliant header) by a custom one 
to increase C++ compatibility as stdatomic.h doesn't work in C++!

(I would like to thanks the one(s) who thought it was a good idea
***not*** to include stdatomic.h -and thread.h- in the C++ standard!)

Patrick Pelissier 7d6f1861c9 Remove use of atomic_uint_fast8_t: 
this type may not be available on all targets.
Use plain atomic_uchar instead.

Use of atomic_load to read an atomic_uchar.

Remove const from prototype since atomic_load
doesn't support const pointers.
