lib/atoi/a2i.[ch]: Add const-generic macros
...
These overloaded macros allow passing either a const or a non-const
endp, and will call the appropriate function. This kind of const
overloading has prior art in C23's string functions, such as memchr(3).
Martin suggested using an artificial function pointer in _Generic(3); it
allows switching on various types at the same time.
Also add a comment referring to liba2i's PDF manual for documentation.

lib/atoi/strtou_noneg.[ch]: Add strtou_noneg()
...
It's like strtou_(), but rejects negative input, instead of silently
converting it to unsigned.

lib/atoi/strtoi.[ch]: strtoi_(), strtou_(): Add functions
...
These functions are identical to strtoi(3bsd) and strtou(3bsd), except
for one important thing: if both ERANGE and ENOTSUP conditions happen,
the BSD functions report ENOTSUP, which is bogus; our strtoi_() and
strtou_() report ERANGE.
