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.
