Refactor code building relation options

Browse Source 
Historically, the code to build relation options has been shaped the
same way in multiple code paths by using a set of datums in input with
the options parsed with a static table which is then filled with the
option values.  This introduces a new common routine in reloptions.c to
do most of the legwork for the in-core code paths.
