- VM_KERN_NOPAGEZERO feature is gone

- sys_getbiosbuffer feature is gone (from kernel; available from vm)
- bump version number because munmap() calls that newly compiled binaries
  will do trigger an ugly (but harmless) error message in older VM's
- some new VM calls and flags, the new IPC calls
- some new CR0 register bits
- added files for shared memory
