<sys/types.h> (if KERNEL is defined). This allows removing bogus dependencies on vm stuff in several places (e.g., ddb) and stops <vm_param.h> from depending on <vm_param.h> Added declaration of boolean_t to <vm/vm.h> (if KERNEL is not defined). It never belonged in <vm/vm_param.h>. Unfortunately, it is required for some vm headers that are included by applications. Deleted declarations of TRUE and FALSE from <vm/vm_param.h>. They are defined in <sys/param.h> if KERNEL is defined and we'll soon find out if any applications depend on them being defined in a vm header.
