[PATCH] usr/bin strings cleanups

[Dion Blazakis <dion.blazakis@xxxxxxxxx>]

Hi,

These patches to src/usr.bin/strings:
* Make src/usr.bin/strings WARN6 clean.
* Remove (void) casts.

Also:
* Add some an #include to two include files so we can safely include
them in a WARN6 clean file.

To make strings compile clean, I patched some include files.  I'm
pretty sure there's something I'm missing, so take a look.

If there's a better way to generate patches, let me know.

Apologies if this is sent twice, I attached the patches at first, but
I forgot MIME encoding is not allowed on the list.
