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.
