Alejandro Colomar f14670ee1a lib/, src/: Replace strtou[l]l(3) by strtou[l]l_noneg() ...

strtou[l]l(3) silently converts negative numbers into positive.  This
behavior is wrong: a negative value should be parsed as a negative
value, which would underflow unsigned (long) long, and so would return
the smallest possible value, 0, and set errno to ERANGE to report an
error.
