Store redirect information for ALL_SESSION and ALL_USER in a hash. This is a speedup if many of these exist (compared to checking a linked list for matches as before). Refactor a bit while here. Use the uthash code from Troy D. Hanson, http://troydhanson.github.com/uthash/

#User configuration
username = "awestfahl"
password = "test"
sip_aor = "sip:awestfahl@tera.ics.keio.ac.jp"

#Destination information
destination_realm = "freediameter.net"
destination_sip = "sip:awestfahl@freediameter.net"
