_POSIX_SOURCE was a POSIX.1-1990 creation that was soon made
obsolete bu _POSIX_C_SOURCE. Retaining mention of it
in the feature test macro requirements section of the
SYNOPSIS doesn't contain important information, and may
mislead readers into actually trying to use this macro.
A few mentions of it a maintained in a some pages where
defining _POSIX_SOURCE inhibits some behavior.

Under the FTM requirements all of these pages document the
requirement for _ISOC99_SOURCE. And feature_test_macros(7) now
documents that "cc -std=c99" produces the same effect as defining
_ISOC99_SOURCE. So, all of these pages don't additionally need
to specify "or 'cc -std=c99'" under the FTM requirements
in the SYNOPSIS. Removing that redundant text also simplifies
the SYNOPSIS a little.

_XOPEN_SOURCE_EXTENDED is obsolete (it existed in SUSv1, but not
subsequent standards). _XOPEN_SOURCE >= 500 produces the same
effects as (_XOPEN_SOURCE && _XOPEN_SOURCE_EXTENDED). Modifying
the SYNOPSIS of various ages that contain:

    _XOPEN_SOURCE\ >=\ 500 ||
        _XOPEN_SOURCE\ &&\ _XOPEN_SOURCE_EXTENDED

to just:

    _XOPEN_SOURCE\ >=\ 500

This has the following benefits:

a) Simplifying the SYNOPSIS by removing ancient
   historical information.

b) Preventing users from being misled into using
   _XOPEN_SOURCE_EXTENDED in new source code.
