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.

6618749e5a Per XPG, if the file descriptor argument to mmap() refers to a file whose 
type is not supported (neither VREG nor VCHR, or not a vnode at all), fail
with ENODEV instead of EINVAL.

14cd99880c Fix the shared library versioning snafu caused by the recent changes 
to the stat(2) family and msync(2).  This uses a primitive function
versioning scheme.

This reverts the libc shared library major version from 13 to 12, and
adds a few new interfaces to bring us to libc version 12.20.

From Frank van der Linden <fvdl@NetBSD.ORG>.

8c0a9bab00 Don't cast 64bit (off_t) file sizes to vm_offset_t (32bit on many 
architectures), truncate them intelligently instead.
The truncation is done centralized in vnode_pager.c.
This prevents from wrap-over effects when parts of large (>2^32 byte) files
are mmapped.
Don't allow to mmap above the numerical range of vm_offset_t.
This is considered a temporary solution until the vm system handles the
object sizes/offsets more cleanly.

801712f01a Extend use of vm_object_prefer() to vm_allocate_with_pager(). 
Make vm_object_prefer() call MD aligner for "pageless" objects too,
so we can have more control over the virtual address to be used.

Implementation could be simpler if we by-pass the object to mapped, but
we'd loose the ability to adapt alignment to objects that were previously
mmap'ed with MAP_FIXED on.
