GCC's NULL is actually __null, which allows detecting some questionable
NULL usage and warn about it. Moreover each platform/compiler should
have its own stddef.h anyway (which is different from linux/stddef.h).
So there's no good reason to leak kernel's NULL to userspace and
override what the compiler provides.

* a generic boolean-type, named 'bool'
* aliases to 0 and 1, named 'false' and 'true'
Removing colliding definitions of 'bool', 'false' and 'true'.

It's not used by anything user-visible, and it make g++ unhappy.

Current gcc 3.5 doesn't compile a x86-64 kernel, because it doesn't
recognize the offsetof used in asm-offset.c to be constant.
Use __builtin_offsetof for this instead.
