pf_pf_get_sport(): Prevent possible endless loop when searching for an unused
nat port
Attached is a "port" of Alexander Bluhm's OpenBSD commit r1.60.
The first chunk had to be modified because on OpenBSD the
'cut' declaration is located elsewhere.
OpenBSD commit message:
Use a 32 bit variable to detect integer overflow when searching for
an unused nat port. Prevents a possible endless loop if high port
is 65535 or low port is 0.
