Fix overflow in parsing of positional parameter
Replace atol with pg_strtoint32_safe in the backend parser and with
strtoint in ECPG to reject overflows when parsing the number of a
positional parameter. With atol from glibc, parameters $2147483648 and
$4294967297 turn into $-2147483648 and $1, respectively.
