Here's the last of my doc patches for now....

With the exception of some of the more recently written parts of the GDB doc, 
there appears to be a strong convention of capitalizing only the first word of 
section titles.  (All the major words in chapter and appendix titles are 
capitalized.)  Some of the section titles do not follow this convention.  This 
is most visible when you read the table of contents in the TeX-generated output. 
  This patch makes all the section titles consistently capitalized.

Some comments:

* I also changed one of the node titles to be plural (see the changelog entry), 
since it seemed like the singular form didn't make sense.

* I changed the capitalization of all the references I could find to these 
sections.  Two of those sections (the "free software" sections) are referenced 
in the document license.  I don't know if changing the license in this way might 
be an issue.  If so, I guess we could leave those section titles as they were.

* A good number of the changes here are to subheadings and subsubheadings in the 
GDB/MI chapter.  These don't normally show up in the table of contents, so their 
inconsistent capitalization is much less visible.  If you don't want to change 
all these headings for some reason, I don't think they matter as much as the 
other sections.
