909d5c6308 Isolate PCB-specific ethertalk DDP functions in ddp_pcb.c, removing them
from ddp_usrreq.c.  Functions moved are:

  at_pcballoc()
  at_pcbconnect()
  at_pcbdetach()
  at_pcbdisconnect()
  at_pcbsetaddr()
  at_sockaddr()

Also moved are ddp_ports and ddpcb, global variables associated with DDP
pcbs.  This makes PCB implementation more parallel to inet, inet6, and
ipx.

a5c7e3bb70 Prevent the strange situation that after each load/unload of a ppbus
device, the device is probed multiple times (so each device is
detected N times after unloading/loading the module N-1 times).

The real fix is (quote Doug and Warner):
> : In an ideal world, there should be some kind of BUS_UNIDENTIFY method
> : which a driver could use to delete the devices it created in
> : BUS_IDENTIFY.
>
> Or the bus would have a driver deleted routine that got called and it
> would remove all instances of the devclass attached to it.

7cd53fdda8 Utilize sf_buf_alloc() and sf_buf_free() to implement the ephemeral
mappings required by mdstart_swap().  On i386, if the ephemeral mapping
is already in the sf_buf mapping cache, a swap-backed md performs
similarly to a malloc-backed md.  Even if the ephemeral mapping is not
cached, this implementation is still faster.  On 64-bit platforms, this
change has the effect of using the direct virtual-to-physical mapping,
avoiding ephemeral mapping overheads, such as TLB shootdowns on SMPs.

b4f5ef7eac sAdd a comment indicating why there continues to be a race condition in
the tap driver, even with Giant over the cdev operation vector, due to
a non-atomic test-and-set of the si_drv1 field in the dev_t.  This bug
exists with Giant under high memory pressure, as malloc() may sleep
in tapcreate(), but is less likely to occur.  The resolution will
probably be to cover si_drv1 using the global tapmtx since no softc is
available, but I need to think about this problem more generally
across a range of drivers using si_drv1 in combination with SI_CHEAPCLONE
to defer expensive allocation to open().

Correct what appears to be a bug in the original if_tap implementation,
in which tapopen() will panic if a tap device instance is opened more
than once due to an incorrect assertion -- only triggered if INVARIANTS
is compiled in (i.e., when built into a kernel).  Return EBUSY instead.

Expand mtx_lock() coverage using tp->tap_mtx to include tp->ether_addr.

b7e23e826c - Replace wait1() with a kern_wait() function that accepts the pid,
options, status pointer and rusage pointer as arguments.  It is up to
  the caller to copyout the status and rusage to userland if needed.  This
  lets us axe the 'compat' argument and hide all that functionality in
  owait(), by the way.  This also cleans up some locking in kern_wait()
  since it no longer has to drop locks around copyout() since all the
  copyout()'s are deferred.
- Convert owait(), wait4(), and the various ABI compat wait() syscalls to
  use kern_wait() rather than wait1() or wait4().  This removes a bit
  more stackgap usage.
