the "-D" output (Dump additional internal tables), update the tests to
actually generate the data!
This lets us re-enable 28 of the 30 "skipped" tests.
XXX Still need to work on tests n12 and n17_6
When a xenstore watch triggers, the event is processed on process_msg
and if a valid handle it's found the handler is queued for execution
on the pending xen watches queue (watch_events).
This may present a problem if we trigger a xenwatch several times and
then disconnect the device. If several xenwatch events are added to
the watch_events queue and the device is disconnected afterwards, the
first processed xenwatch event will disconnect the device, remove the
watch and free all resources. This triggers a panic if there are
pending xenwatch events for that device already queued in the local
queue of the function xenwatch_thread, since when the next watch that
has the same handler tries to execute we get a panic due to the fact
that the device is already disconnected and all resources had been
freed:

- Implement NGONE to fix caching issue described in PR kern/25070.
Mostly taken from FreeBSD r125637.
- Revert revision 1.70 of smbfs_vnops.c to fix setattr to opened
direcotry. In case of SMB_CAP_NT_SMBS, NOPEN is set after
smbfs_smb_ntcreatex() call. If NOPEN is set in front, it will
immediately return by condition at do_open label.
- In smbfs_close(), call smbfs_smb_close() and drop NOPEN bit in
the case of direcotry. Otherwise smbfs_rmdir() fails when the
directory was opened.
