Complete _BSD_SOURCE / _SVID_source followup cleanup.
This patch completes the headers cleanup consequent on removal of _BSD_SOURCE and _SVID_SOURCE (apart from any subsequent deprecations): * #endif conditionals that referred to BSD or SVID are updated. * Redundant __USE_* tests in cases involving __USE_MISC are removed. This includes cases such as __USE_MISC || __USE_ISOC99, where __USE_MISC is redundant (because __USE_MISC is only ever defined in the default / _DEFAULT_SOURCE / _GNU_SOURCE case, when __USE_ISOC99 is also defined; the same applies to the non-XSI-extended POSIX versions), and cases involving __USE_GNU, where __USE_GNU is redundant (because if __USE_GNU is defined, so are the other __USE_* macros). There may well be other cases of __USE_FOO || __USE_BAR tests that could be simplified because one macro implies the other; this patch only addresses cases involving __USE_MISC.
