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.
should be done in PREROUTING so it can be acted on later". If a
rule has both tagging and classification options, the rule should
be split so that iptables command doing tagging goes in PREROUTING
and rule doing classification goes into POSTROUTING chain.

compiling single rule with IPv6 destination and IPv4 gateway or
interface". Routing compiler for iptables does not support ipv6 at
this time and will issue a warning when user tries to place ipv6
address or network in a routing rule. The warning does not appear
when ipv6 address is a member of a group used in the rule. Also
see #1575.
rule action for Continue". Rules with action "Continue" should
translate into iptables commands without "-j TARGET" parameter. If
such rule also has logging enabled, it should use target "-j LOG"
instead of generating additional chain.
MAC-matching rules not generated properly". Iptables NAT rules
matching a group of host objects with both IP and MAC addresses each
in "Original Source" were not generated properly.
3178186 "Add ND/NS allow rules for the FORWARD chain". Rules that are
added automatically to ipv6 Linux firewall to permit neighbor discovery
packets should be also added to the FORWARD chain if the firewall is
a bridge.

rule element by name after group is expanded, this helps ensure
stable ordering of objects in generated configuration.
* Compiler.cpp (replaceClusterInterfaceInItfRE::processNext):
sorting objects in rule element after cluster interfaces have been
replaced, this helps ensure stable ordering of objects in generated
configuration.
* FWObject.h (FWObjectNameCmpPredicate): moved this class from
gui-specific module to libfwbuilder as it is universally useful.
It can compare FWObject objects by name and can optionally can
follow references; it can be used with std::sort() to sort lists
of FWObject pointers or directly sort rule elements.
