+- Add a Cisco-Avpair with intercept details to RADIUS Start/Stop
+ records.
+- Don't use LOG() macro in initdata() until the config struct has been
+ allocated (uses config->debug).
+- Initialise log_stream to stderr to catch errors before the config file
+ is read.
+- Fix leak in session freelist when initial RADIUS session allocation
+ fails.
+- Don't process C_LASTSEEN unless we're a master (otherwise a crashed
+ master kills all slaves once restarted).
