45fd598f49 Add the function memmem(3) as found in glibc and others.
It is the binary equivalent to strstr(3).

 void *memmem(const void *big, size_t big_len,
	const void *little, size_t little_len);

a659824fbd According to the information on:
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.

2ac758c6fa Mark functions pure where applicable. A notable exclusion is strcoll(),
which is not strictly pure because it calls malloc()/free() in some cases.

89b1ef2eaa Change the definition of NULL on ia64 (for LP64 compilations) from
an int constant to a long constant. This change improves consistency
in the following two ways:
1. The first 8 arguments are always passed in registers on ia64, which
   by virtue of the generated code implicitly widens ints to longs and
   allows the use of an 32-bit integral type for 64-bit arguments.
   Subsequent arguments are passed onto the memory stack, which does
   not exhibit the same behaviour and consequently do not allow this.
   In practice this means that variadic functions taking pointers
   and given NULL (without cast) work as long as the NULL is passed
   in one of the first 8 arguments. A SIGSEGV is more likely the
   result if such would be done for stack-based arguments. This is
   due to the fact that the upper 4 bytes remain undefined.
2. All 64-bit platforms that FreeBSD supports, with the obvious
   exception of ia64, allow 32-bit integral types (specifically NULL)
   when 64-bit pointers are expected in variadic functions by way of
   how the compiler generates code. As such, code that works correctly
   (whether rightfully so or not) on any platform other than ia64, may
   fail on ia64.

To more easily allow tweaking of the definition of NULL, this commit
removes the 12 definitions in the various headers and puts it in a
new header that can be included whenever NULL is to be made visible.

This commit fixes GNOME, emacs, xemacs and a whole bunch of ports
that I don't particularly care about at this time...

9e6f796b0d o Merge <machine/ansi.h> and <machine/types.h> into a new header
called <machine/_types.h>.
o <machine/ansi.h> will continue to live so it can define MD clock
  macros, which are only MD because of gratuitous differences between
  architectures.
o Change all headers to make use of this.  This mainly involves
  changing:
    #ifdef _BSD_FOO_T_
    typedef	_BSD_FOO_T_	foo_t;
    #undef _BSD_FOO_T_
    #endif
  to:
    #ifndef _FOO_T_DECLARED
    typedef	__foo_t	foo_t;
    #define	_FOO_T_DECLARED
    #endif

1802268e80 o Move some function prototypes from <string.h> to the newly rewritten
<strings.h>, based on POSIX.1-2001's requirements.
o Add 'restrict' qualifier (spelled '__restrict') to functions in

o Properly expose new POSIX.1-2001 functions in <string.h>.
