unused parameters and variables are annotated with
(void)foo; /* UNUSED */
instead of __unused, because this code needs to build
also on linux and windows.

"globalport" option for multiple NAT instances.
If ipfw rule contains "global" keyword instead of nat_number, then
for each outgoing packet ipfw_nat looks up translation state in all
configured nat instances. If an entry is found, packet aliased
according to that entry, otherwise packet is passed unchanged.
User can specify "skip_global" option in NAT configuration to exclude
an instance from the lookup in global mode.

Usual moving of code with no changes from ipfw2.c to the
newly created files, and addition of prototypes to ipfw2.h
I have added forward declarations for ipfw_insn_* in ipfw2.h
to avoid a global dependency on ip_fw.h
