mrg 6b11eea5b2 reject attempts to map an immutable or append-only file, shared with ...

write protection.  this stops data corruption where it was possible
to change the in-memory copy of an append-only file (but not the on-disk
copy).  this is documented in NetBSD security advisory 1998-003.  thanks
to darrenr, lukem, cgd, mycroft and mrg for this.
