Log Message:
Merge jdolecek-ncqfixes branch

- ata_xfer's are dynamicall allocated as needed using a pool, no longer
  limited to number of possible openings supported by controller; dump
  and recovery paths use dedicated pre-allocated storage
- moved callouts and condvars from ata_xfer to queue or channel, so that
  ata_xfer does not need special initialization
- slot allocation now done when xfer is being activated, uncoupled
  from memory allocation; active slots are no longer tracked by controller
  code
- channel and drive reset is done always via the atabus thread, and
  now executes with channel locked the whole time
- NCQ recovery moved to shared function, and run via the thread also
- added some workarounds for buggy error recovery AHCI emulation in QEMU
  and Parallels

designed to primarily fix kern/52614, but might also help with kern/47041
and kern/53183
