As per previous commit, mention of _XOPEN_SOURCE_EXTENDED
has generally been removed from the man pages.

_XOPEN_SOURCE_EXTENDED is obsolete (it existed in SUSv1, but not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.

It seems that adjtimex() never needed _BSD_SOURCE (and my
earlier commit 5918743bc8 was simply a blunder.

Looking at <features.h> (or feature_test_macros(7)), one can
see that when _XOPEN_SOURCE is defined with the value 700
(or greater), then _POSIX_C_SOURCE is defined with the value
200809L (or greater). Therefore, terms in the man pages such as
_XOPEN_SOURCE\ >=\ 700 || _POSIX_C_SOURCE\ >=\ 200809L
can be simpified to:
_POSIX_C_SOURCE\ >=\ 200809L

Emphasize that defining _XOPEN_SOURCE >=500 produces same
effects as defining _XOPEN_SOURCE_EXTENDED.

The text has an incorrect description in NOTES, it says
that (2^32/HZ) - 300 is about 429 million. It is correct
only if HZ=10 which does not look common today. So just
removing "(i.e., about 429 million)" is good enough.
