Version 3.0 and 3.2

Matthew has tagged version 3.2 here: https://github.com/FreeRADIUS/freeradius-server/tree/v3.2.x We will use 3.2 as the new "minor features" branch. Matthew has already pulled in a few PRs. Version 3.2 (and any later 3.x) will also be 99.99% compatible with 3.0. So the upgrade process will be painless. We have now marked 3.0 as "security and bug fixes only". There will be no new features in 3.0. We will continue to maintain both the 3.0 and 3.2 branches for the foreseeable future. Alan DeKok.
