documentation: Manual reference fixes for mega-manual processing

I fixed several occurences of cross-references to whole manuals where
the formatting was split in the <ulink> statement.  The <ulink> tag
and the manual title must be on one DocBook line in order for the
sed scripts to correctly process the links when the mega-manual is
created.
