d05090827f Back out the `hiding' of strlcpy and strlcat. Several people
vocally objected to this safety belt.

5723e501ab `Hide' strlcpy and strlcat (using the namespace.h / __weak_reference
technique) so that we don't wind up calling into an application's
version if the application defines them.

Inspired by:	qpopper's interfering and buggy version of strlcpy

e37f8b5313 Optimize errstr() by reducing the number of times it walks a string.
As a side effect, it makes the code easier to read and requires less
pointer arithmetic.

68cd9bedfb Stylistic changes:
o Fix an English error (comma splice) and poorly worded sentence.
o Fix KNF ordering of variables (pointers come before arithmetic types).
o Restore hand-optimization of sizeof()-1, instead of strlen().
o Remove unneeded local variables in strerror_r().

5a98f074e6 Rearrange strerror() so that its itoa procedure can be used with
strerror_r().  Doing this allows us to ensure that strerror_r() always
fills the supplied buffer regardless of EINVAL or ERANGE errors.

strerror()'s semantics have changed slightly such that an argument of
0 is now considered invalid and errno is set to EINVAL.

Remove internal regression test for strerror() and strerror_r().  This
will be reincarnated in src/tools/regression/lib/libc/string.

In strerror(3), add a comment about strerror()'s bogus return type.

fcd7f38f46 Replace wcsstr() with an implementation based on strstr(), which is far
more efficient. The problem with the previous implementation was that it
calculated the length of the first argument ("big") with wcslen() when
it was not necessary.

bc0ad8e7a1 - Let their manual pages show the reader that the bzero(3) and
bcopy(3) functions are prototyped in <strings.h> and not in
   <string.h> anymore.
 - Add a sentence about that to the respective HISTORY sections.
In the C source files:
 - Include <string.h> or <strings.h> depending on what function
   is to be compiled.
 - Use ANSI-C function definitions.

 - Include <strings.h> instead of <string.h>.

c9ab23eea5 - Convert the function definition to declare its arguments
in the ANSI-C format.
 - Change the code a bit to hopefully save some cycles.
   I.e. (simplified) change

     a = b + 1;
     while (--b & 0x7)
	/* ... */
   to
     a = b;
     for (; b & 0x7; b--)
	/* ... */
   and
     while (--a >= 0)
	/* ... */
   to
     for (; a > 0; a--)
	/* ... */
 - Equip two function arguments of swab() with the 'restrict'
   type qualifier in form of the '__restrict' macro.  This is
   specified by POSIX.1-2001.

425289a9db - Update the manual pages of index() and rindex() to show
<strings.h> as the associated header file.
   The prototypes have been moved there from <string.h> because
   POSIX.1-2001 said so.
 - Conditionally include either <strings.h> or <string.h> based
   on whether the [r]index() or str[r]chr() functions are
   compiled, respectively.
 - Style(9) tells us to
    - put a space after the return keyword
    - to check for a NUL character without using the ! operator.
    - use NULL instead of (type *)NULL where the compiler knows
      the type.
   Apply these rules.
 - Rather use ANSI-C function definitions than K&R ones.
 - For index(3), correct second function argument's type; it was
   declared to be a `const char' before and is now an `int'.

554331bbb9 - Update the manual page to show that the associated header file

 - Tell the reader about this change in the HISTORY section.
 - Switch to use an ANSI-C function definition.
 - Include <strings.h> instead of <string.h> in the source file.

c271a3613c - Update strcasecmp(3)/strncasecmp(3) to reflect the fact that
the prototypes for both functions are now in the <strings.h>
   header, as required by IEEE Std 1003.1-2001.
 - Add one sentence about that in the HISTORY section.
 - Include <strings.h> in the source file to have the prototypes
   in scope when the _ANSI_SOURCE macro is defined.

ad90696815 - Add the 'restrict' qualifier to the definitions of the string

 - Change the manual page accordingly.
