Merge index() and strchr() together.

As I looked through the C library, I noticed the FreeBSD MIPS port has a hand-written version of index(). This is nice, if it weren't for the fact that most applications call strchr() instead. Also, on the other architectures index() and strchr() are identical, meaning we have two identical pieces of code in the C library and statically linked applications. Solve this by naming the actual file strchr.[cS] and let it use __strong_reference()/STRONG_ALIAS() to provide the index() routine. Do the same for rindex()/strrchr(). This seems to make the C libraries and static binaries slightly smaller, but this reduction in size seems negligible.

as the associated header file. The prototypes have been moved there from because POSIX.1-2001 said so. - Conditionally include either or 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'.

Remove 'register' keyword.

Make the rcsid and FreeBSD IDs more sane in the wcs* and wmem* files.

Do the same for the non-wcs*/wmem* files while I'm here.
