and Daichi GOTO <daichi@FreeBSD.org> for submitting this
major rewrite of unionfs. This rewrite was done to
try to solve many of the longstanding crashing and locking
issues in the existing unionfs implementation. This
implementation also adds a 'MASQUERADE mode', which allows
the user to set different user, group, and file permission
modes in the upper layer.

This will allow the NFS mount code to return a string error message

and it only saved 1 bit which isn't principal, even less now
that the underlying issue with the total of virtual memory has
been fixed. (For the record, it will overflow with >=2T of
VM total, with 32-bit ints used to keep counters in pages.)
- While here, fix printing of other "struct vmtotal" members
such as t_rq, t_dw, t_pw, and t_sw as they are also signed.

address learned by the bridge is made permanent, the address will not age out

This can be used to stop mac address poisoning or clients roaming in much the
same way as static entries without the hassle of preloading the table.
compatible, it would have to (at least):
- support the "compat-compat" -T option,
- *not* support the -l, -O, and -v options,
- default to soft updates being disabled.
Worse, the compatibility mode makes it impossible to mount_mfs(8)
a file system from fstab(5) with soft updates disabled (-S). [1]
Now, the only difference when called as "mount_mfs" or "mfs" (as
opposed to "mdmfs") is that the file mode of the mount point is
set by default to 01777. All options available to mdmfs(8) are
also available to mount_mfs(8); the -C option is still recognized
but ignored for backward compatibility.

It is safe when gjournal is running on top of gmirror/graid3.
RSTP provides faster spanning tree convergence, the protocol will exchange
information with neighboring switches to quickly transition to forwarding
without creating loops. The code will default to RSTP mode but will downgrade
any port connected to a legacy STP network so is fully backward compatible.

This has been happening due to the priority inversion; options
specified on the command line should take precedence over options
from fstab over default "noro" option, but since both the default
"noro" and options specified on the command line (-w, -r, -o ...)
were put into the same "options" variable, "noro" took precedence
over fstab "ro" (this is easily visible with "mount -d").
