Cistron Radius Server

Security fixes and minor feature enhancements were
made.

Several memory leaks were fixed. A bug with executing external shell scripts was fixed. There were some additional minor bugfixes and feature enhancements.

The trailing \0 that Ascend likes to add is now ignored when storing the last 8 bytes of session ID in radutmp, port ranges have been fixed so that they actually work, alignment fixes have been made in the output of radwho (esp. for portnumbers > 999), HPUX, BSDi, and AIX fixes have been made, "make install" now also populates /etc/raddb, debug output now prints IP addresses in dot notation instead of hex, radtest has been added to the install target, debugging mode (-xx) now notes when duplicate attributes are NOT moving into the reply, and more sanity checking and error messages are now used when parsing the 'users' file.

Fixes for "nostrip" option in realms file, /RADIUSD/ANY/SHELL compare in auth.c, and a bug in proxy.c which would leak memory if the end server never replied to the accounting request, and writing "reject" to radius.log in auth.c if login incorrect due to Auth-Type = Reject.

A fix for potential buffer overflows, a compatibility mode for 1.5.4.3 dictionaries, cleanups, and sanity checks.
