Testing pre-2.2.0

[Alan DeKok]

  We're (again) close to releasing 2.2.0.  This time for real.

  In order to make the server more future-proof, I've made some changes
to the TTLS parser.  This will solve issues in the long term.  But it
needs more testing now.

  Please try the git "v2.1.x" branch with various supplicants, and TTLS.
 Please post here if it works / fails.

  Thanks.

  Alan DeKok.
