Add kbuild.h that contains common definitions for kbuild users
The same definitions are used for the bounds logic and the asm-offsets.h generation by kbuild. Put them into include/linux/kbuild.h file. Also add a new feature COMMENT("text") which can be used to insert lines of ocmments into asm-offsets.h and bounds.h.
