Version 2.2.4 has been released

[Alan DeKok]

  The changes from 2.2.3 are minor.

Feature improvements

* A "panic_action" can be set to have the server dump a gdb log on SEGV
or other fatal error.
* allow radmin command "set module status <module> <code>" which can be
used to forcibly enable/disable modules.

Bug Fixes

* If the server fails to bind() after fork(), that is now reported to
the parent, which exits with an error.
* Session / delay times in MySQL are unsigned int.
& Use --tag=CC for libtool. Closes #497. Because libtool is too stupid
to notice that compiling means compilation.
* Fix bug when copying attributes for vendors > 32767
* Fix behaviour on FreeBSD where sending packets from an interface bound
to an IP address would fail when the server was built with udpfromto.
* Don't fail config check if were listening on an IP which is also a
home server. Some deployments have valid reasons to loop packets back to
another virtual server.
* Use correct port when DHCP relaying.
* Set source IP address for DHCP packets from DHCP-Server-IP-Address, or
DHCP-DHCP-Server-Identifier, if we're unable to otherwise determine the
source IP.
