Diff to previous 1.53 (colored)

- make pipe->close method take the thread lock

- convert usb_taskq to use mutex/cv

- convert needs_explore usage into a cv on the thread lock

- remove KERNEL_*LOCK from uaudio and umidi, since we're supposedly
  MPSAFE here now

- use IPL_SCHED instead of IPL_USB (aka biglocked) interrupts

- drop the audio thread lock when calling into usb when it may sleep,
  avoiding a deadlock between audiowrite and audioioctl.  this fixes
  mixerctl -a vs. playing hanging the system
  XXX probably need to check this in a bunch more places.
