documentation: converted ref-variables-gloss to chapter.

As part of moving the reference manual to a real reference manual I
am removing the "appendix" classification and having everthing be
a chapter.  I changed the "ref-varibales-gloss" appendix to a chapter and
made sure any references in the doc set use the proper term now
(chapter).
