[Jeffrey Hsu]

	This commit broke the build of linuxpluginwrapper which
	does the following:

	#define _KERNEL
	#include <sys/socket.h>
	#undef _KERNEL

	to obtain typedefs, structs and macros, but not function declarations
	at the end of the <sys/socket.h>.  After the commit, it now includes
	<sys/libkern.h>, which includes <sys/systm.h>, which declares string
	manipulation functions with arguments slightly different from ones
	declared in <string.h>.

Which typedefs, structs, and macros inside _KERNEL does it need?  Maybe
we could move those outside _KERNEL.

	I don't know which one is to be fixed, the linuxpluginwrapper port or
	<sys/socket.h>, but if I need to fix linuxpluginwrapper, how can I do
	that without the `#define _KERNEL'?

Here's a suggested gross hack:

#define _SYS_LIBKERN_H_
#define _KERNEL
#include <sys/socket.h>
#undef _KERNEL

or

#define _SYS_SYSTM_H_
#define _KERNEL
#include <sys/socket.h>
#undef _KERNEL
