'Itoc' converts the integer given as its first parameter to a character
string that is returned as its second parameter.  The last 'size' - 1 digits
of the number, and no more, are returned.
The number is left justified, with a leading minus sign if
the number is negative.
The function return is the length of the character string
returned.
.im
'Itoc' performs a rather standard conversion by using modular arithmetic
to fetch one digit at a time from the integer value supplied.  The character
string generated is placed backward in the receiving field, then reversed
just before exit.
