features.h: Rework _DEFAULT_SOURCE
The (glibc) documentation for _DEFAULT_SOURCE states:
The "default" definitions comprise those required by
POSIX.1-2008 and ISO C99, as well as various definitions
originally derived from BSD and System V. On glibc 2.19
and earlier, these defaults were approximately equivalent
to explicitly defining the following:
cc -D_BSD_SOURCE -D_SVID_SOURCE -D_POSIX_C_SOURCE=200809
It also states that _BSD_SOURCE and _SVID_SOURCE are deprecated, and
have the same effect as setting _DEFAULT_SOURCE.
Therefore, when any of _BSD_SOURCE, _SVID_SOURCE or _DEFAULT_SOURCE is
set, the three macros should be set, and POSIX 2008.09 compatibility
should be enabled.
