a67fbaa46c - Add getdelim(), getline(), stpncpy(), strnlen(), wcsnlen(), 
wcscasecmp(), and wcsncasecmp().
- Make some previously non-standard extensions visible
  if POSIX_VISIBLE >= 200809.
- Use restrict qualifiers in stpcpy().
- Declare off_t and size_t in stdio.h.
- Bump __FreeBSD_version in case the new symbols (particularly
  getline()) cause issues with ports.

28465baaf0 Add restrict qualifiers to the parameters to strlcpy() and strlcat(). 
The annotation mainly just serves as a hint that they're not intended
for use with overlapping strings.

12e5c4fd4c Rewrite of MI strlen(3) in a way that can better utilize modern hardware by 
reducing branches and doing word-sized operation.

The idea is taken from J.T. Conklin's x86_64 optimized version of strlen(3)
for NetBSD, and reimplemented in C by me.

87aa297030 Replace the current strspn() and strcspn() with significantly faster 
implementations inspired by the ones in DragonFly.  Unlike the
DragonFly versions, these have a small data cache footprint, and my
tests show that they're never slower than the old code except when the
charset or the span is 0 or 1 characters.  This implementation is
generally faster than DragonFly until either the charset or the span
gets in the ballpark of 32 to 64 characters.

http://www.opengroup.org/onlinepubs/009695399/functions/swab.html
the prototype for swab() should be in <unistd.h> and not in <string.h>.
Move it, and update to match SUS.  Leave the prototype in string.h for
now, for backwards compat.
