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/

There is a package script available for the OpenWRT platform.

Please refer to contrib/OpenWRT/HOWTO for more information.
