Fixes to the softdep code from Ethan Solomita <ethan@geocast.com>.
...
* Fix buffer ordering when it has dependencies.
* Alleviate memory problems.
* Deal with some recursive vnode locks (sigh).
* Fix other bugs.

Add a new flag, used by vn_open() which prevent symlinks from being followed
...
at open time. Use this to prevent coredump to follow symlinks when the
kernel opens/creates the file.

Add support for fcntl(2) to generate VOP_FCNTL calls. Any fcntl
...
call with F_FSCTL set and F_SETFL calls generate calls to a new
fileop fo_fcntl. Add genfs_fcntl() and soo_fcntl() which return 0
for F_SETFL and EOPNOTSUPP otherwise. Have all leaf filesystems
use genfs_fcntl().

Previous change to vn_lock() was bogus. If we got EDEADLK, it was from
...
lockmgr(), and it already unlocked v_interlock. So, just return in this case.

Prevent deadlock cited in PR4629 from crashing the system. (copyout
...
and system call now just return EFAULT). A complete fix will
presumably have to wait for UBC and/or for vnode locking protocols to
be revamped to allow use of shared locks.

Modify VOP_CLOSE vnode op to always take a locked vnode. Change vn_close
...
to pass down a locked node. Modify union_copyup() to call VOP_CLOSE
locked nodes.
Also fix a bug in union_copyup() where a lock on the lower vnode would
only be released if VOP_OPEN didn't fail.

Implement support for IEEE Std 1003.1b-1993 syncronous I/O:

* if synchronized I/O file integrity completion of read operations was
requested, set IO_SYNC in the ioflag passed to the read vnode operator.
* if synchronized I/O data integrity completion of write operations was
requested, set IO_DSYNC in the ioflag passed to the write vnode operator.

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. :-)
