fwbuilder/test/ipt/firewall2-4.fw.orig
Vadim Kurland 0aa3eac4d4 * Compiler.cpp (expandGroupsInRuleElement): sorting objects in the 
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.
