* libc: implement common `abs` for various integer sizes * libc: move imaxabs to inttypes.zig and don't use cInclude * libc: delete `fabs` c implementations because already implemented in compiler_rt * libc: export functions depending on the target libc Previously all the functions that were exported were handled equally, though some may exist and some not inside the same file. Moving the checks inside the file allows handling different functions differently * remove empty ifs in inttypes Co-authored-by: Alex Rønne Petersen <alex@alexrp.com> * remove empty ifs in stdlib Co-authored-by: Alex Rønne Petersen <alex@alexrp.com> * libc: use `@abs` for the absolute value calculation --------- Co-authored-by: Alex Rønne Petersen <alex@alexrp.com>
