d09bec0098 Pick up the inode number using VOP_GETATTR() rather than caching it 
in all vnodes on the off chance that linprocfs needs it.  If we can afford
to call vn_fullpath() we can afford the much cheaper VOP_GETATTR().

05758a9b47 Correct a potential DoS vulnerability, as described at 
http://www.securityfocus.com/archive/1/379450

This patch is based on dillon's patch on DragonFlyBSD, which is in
turn derived from OpenBSD's src/usr.sbin/pppd/cbcp.c,v 1.6.

64bf081bc3 Before trying to update metadata (so open consumer for writing), be sure 
that the events queue is empty. In other case we're able to hit the race
where for example da0s1 is tasted by some other class, which means that
da0 is open with exclusive bit set, which means that we can't open da0
for writing if it is our component.

3e514b9f37 Attempt to fix a number of race conditions in the handling of 
transfer timeouts that typically cause a transfer to be completed
twice, resulting in panics and page faults:

 o A transfer completion interrupt could arrive while an abort_task
   event was set up, so the transfer would be aborted after it had
   completed. This is very easy to reproduce. Fix this by setting
   the transfer status to USBD_TIMEOUT before scheduling the
   abort_task so that the transfer completion code will ignore it.

 o The transfer completion code could execute concurrently with the
   timeout callout, leaving the callout blocked (e.g. waiting for
   Giant) while the transfer completion code runs. In this case,
   callout_stop() does not prevent the callout from running, so
   again the timeout code would run after the transfer was complete.
   Handle this case by checking the return value from callout_stop(),
   and ignoring the transfer if the callout could not be removed.

 o Finally, protect against a timeout callout occurring while a
   transfer is being aborted by another process. Here we arrange
   for the timeout processing to ignore the transfer, and use
   callout_drain() to ensure that the callout has really gone before
   completing the transfer.

This was tested by repeatedly performing USB transfers with a timeout
set to approximately the same as the normal transfer completion
time. In the PR below, apparently this occurred by accident with a
particular printer and the default timeout.
