* Compile time checking adjust includes and code for deprecated features
* QHttp class is removed from Qt5 so the custom HttpGet class is
disabled when compiling with Qt5. The api on fwbuilder.org isn't
working, so the code for getting tips and checking if a new version is
available must be rewritten anyway.
for PF and iptables should include not only cluster interfaces, but
also interfaces of all members. This way, we can make compiler
generate configuration
"pass in quick on em0 route-to { ( em0 10.1.1.2 ) } ... "
for a rule of a PF cluster. Here "em0" is an interface of a member,
not the cluster.
