  Log Message:
  -----------
  Increase number of write completion threads, matching ZoL.

Our iSCSI benchmarks on a large 80-core system show that previous limit
of 8 threads can be a bottleneck.  At some points this change increases
write IOPS by as much as 50%

    M sys/dev/usb/usb_hub.c

  Log Message:
  -----------
  Remove the power bit from the super speed root hub port status register
because it clobbers the super speed link status when a device is in super
speed mode. Currently the power bit is not needed for anything in the USB
hub driver.

This fixes USB warm reset for super speed devices.

  Log Message:
  -----------
  Implement a detaching flag for the sound(4) subsystem to take
appropriate actions when we are trying to detach an audio device,
but cannot because someone is using it.

This avoids applications having to wait for the DSP read data
timeout before they receive any error indication.
Tested with virtual_oss(8).

Remove some unused definitions while at it.
