b3e62a9883 Work around a bug in the Linux version of ski, that's specific to 
SSC_GET_RTC. This fixes the panic seen shortly after mounting the
root file system.

48849938e8 Change the all locks list from a STAILQ to a TAILQ. This bloats struct 
lock_object by another pointer (though all of lock_object should be
conditional on LOCK_DEBUG anyways) in exchange for an O(1) TAILQ_REMOVE()
in witness_destroy() (called for every mtx_destroy() and sx_destroy())
instead of an O(n) STAILQ_REMOVE.  Since WITNESS is so dog slow as it is,
the speed-up is worth the space cost.

8dcb900b62 Handle "dead" witnesses better in the situation of several short term locks 
being created and destroyed without a single long-term one around to ensure
the witness associated with that group of locks stays alive.  The pipe
mutexes are an example of this group.  For a dead witness we no longer
clear the witness name.  Instead, when looking up the witness for a lock,
if a dead witness' (a witness with a refcount of 0) w_name pointer is
identical to the witness name of the lock then we revive that witness
instead of using a new witness for the lock.  This results in far fewer
dead witness objects and also better preserves locking orders over the long
term resulting in more correct lock order checking.  Note that we can't
ever derefence w_name of a dead witness since we don't know if the string
it is pointing to has been free()'d or kldunload()'d out from under us.

6438c894da Fixed overflow in the bounds checking in dscheck(). It assumed that 
daadr_t is no larger than a long, and some other relatively harmless
things (*blush*).  Overflow for subtracting a daddr_t from a u_long
caused "truncation" of the i/o for attempts to access blocks beyond
the end of the actually cause expansion of the i/o to a preposterous
size.
