NetBSD/lib/libc/stdio/vsprintf.c
kleink fd5cb0acea A little libc namespace housekeeping exercise:
* Make vfprintf_unlocked() an internal function, c.f. __svfscanf_unlocked().
* Add internal names for arc4random(), endnetpath(), fhstatvfs(),
  fstatvfs(), mkstemp(), shquote(), statvfs(), taddr2uaddr(), uaddr2taddr(),
  uuid_create_nil(), uuid_is_nil(), and wcwidth().
* Include namespace.h where supposed to.
