addr and taddr don't have to be defined any more, so that <sys/mman.h> can be included for proper prototypes of munmap() and friends. - rename our GETPID to MINIX_GETPID to avoid a name conflict with other sources - PM needs its own munmap() and munmap_text() to avoid sending messages to VM at the startup phase. It *does* want to do that, but only after initialising. So they're called again with unmap_ok set to 1 later. - getnuid(), getngid() implementation
