This is a first step toward moving long namelists into a database. I
split the name_record structure into pieces. The goal is that the key
(the name) be separate from the data associated with the key. Databases
such as gdbm store information in [key,content] pairs.
There is no functional change in with this update. It's just a step in
the direction that Jeremy and I have been discussing.
