Confusing comments
Removed RAD_CHECK entry in Perl, protomed RAD_CONFIG

RAD_CONFIG used to be an undocumented read-only clone of RAD_CHECK,
where RAD_CHECK was named incorrectly. Remove the RAD_CHECK, make
RAD_CONFIG read/write.

This should not be merged to 3.0.x, as it breaks backwards
compatibility.
Assume RFC 3542 compliance for IPv6 socket options, which fixes IPv6 support on FreeBSD 10.0
IKEv2 fixes required on our side
Merge pull request #715 from qnet-herwin/perl_remove_rad_config

The default secret is "radsec"
Proxy sockets use common_socket_free().  Closes #680
We can now use talloc_free() for listeners
