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.

lib/atoi/strtou_noneg.[ch]: Add strtou[l]l_noneg()
...
These functions reject negative numbers, instead of silently converting
them into unsigned, which strtou[l]l(3) do.
