Various pages: Simplify mark-up for Feature Test Macro requirements 

Different source styles are used in different pages to achieve the
same formatted output, and in some cases the source mark-up is a
rather convoluted combination of .RS/.RE/.TP/.PD macros. Simplify
this greatly, and unify all of the pages to use more or less the
same source code style. This makes the source code rather easier
to read, and may simplify future scripted global changes.

The feature test macro info is currently bracketed by .nf/.fi
pairs. This is not strictly necessary (i.e., it makes no
difference to the rendered output), but for the moment we keep
these "brackets" in case they may be replaced with something else.
