Vadim Kurland 15bab71f49 * NATCompiler_ipt.cpp (compile): see #2456 Added support for 
single object negation in "Inbound Interface" and "Outbound
Interface" columns in compiler for iptables.

* NATCompiler_pf.cpp (compile): see #2456 Added support for single
object negation in "Interface" rule element of PF NAT rules. Now
compiler can produce PF commands such as "nat on ! em0 ... " (for
PF <4.7) or "match on ! em0 ..." (for PF >= 4.7)

* Compiler.cpp (singleObjectNegation::processNext): moved rule
processor that processes single object negation in any rule
element to the base class Compiler.
