Per IEEE Std 1003.1b-1993, implement the fdatasync() system call which is

identical to fsync() with the expecption of not being required to synchronize
file status information.

Convert fsync vnode operator implementations and usage from the old `waitfor'

Per X/Open CAE Spec Issue 5 Version 2, change the buffer size argument of
...
readlink() from type `int' to type `size_t'. This isn't an ABI change, since
the calling convention of our only LP64 platform (the Alpha) already promotes
this argument to a `long'.
This may not be the final action on this matter; readlink() still returns
an `int', which may change in a future revision of the standard.

Move the permission check in change_owner() back to ufs_vnops::ufs_chown()

again - the facility required in this context would be a filesystem-specific
super-user determination, which is not available yet. Also, add some
clarification to a comment.

* Factor out some permission-checking code from ufs_setattr() into
...
change_owner().
* Change the semantics of chown(), fchown() and lchown(): when requesting a
change of the owner of a file, clear the set-user-id bit; analogous behaviour
for group changes.
* Since the above is a violation of the semantics specified by POSIX and
X/Open, add corresponding compatibility syscalls: __posix_chown(),
__posix_fchown(), __posix_lchown(). (Neither fchown() nor lchown() is
specified by POSIX; the prefix is intended to reflect the semantics.)
* Rename posix_rename() to __posix_rename() to follow the above convention.

initial import of the new virtual memory system, UVM, into -current.

UVM was written by chuck cranor <chuck@maria.wustl.edu>, with some
minor portions derived from the old Mach code. i provided some help
getting swap and paging working, and other bug fixes/ideas. chuck
silvers <chuq@chuq.com> also provided some other fixes.
this is the rest of the MI portion changes.
this will be KNF'd shortly. :-)

Fix the shared library versioning snafu caused by the recent changes

to the stat(2) family and msync(2). This uses a primitive function
