DHCP Logging

[Blake Griffin]

Don't know how this will work for what I want to do.  For options that
do not exist, I want to place something such as "NONE" or "---" into the
log statement where the option value would normally go. If those options
don't exist, the log statement never gets processed.

Check out the pick-first-value function.
