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.
