Testing 3.0/master

[Phil Mayers]

So, I've just compiled up the current "master", and a few things stand 
out. Using my existing 2.1.12 config:

  1. EAP-TTLS/MSCHAP doesn't seem to work any more; the MS-CHAP 
challenge/response are wrong. PEAP works fine. Haven't looked into this yet.

  2. rlm_eap_tls now mandates "private_key_password" even if the key is 
not encrypted on disk. You can specify anything - but you must specify 
it. Behaviour change, but not particularly onerous.

  3. Fast Session resumption seems to give a segfault - request_finish 
calls pairfree on process.c:1085 and the value seems to be corrupt. The 
backtrace is a bit useless, since most of the values are optimised out 
(grr gcc) but I will try to get more info.

Will follow up with more as I figure out the cause(s)
