jdolecek 67238c609c The header part of driver overhault:
* simplify and clean the attach code a lot, and support the 'drive'
  locator
* pass proper dev_t to readdisklabel() - formerly, the passed value was
  completely broken (used incorrect major and wrong minor), but worked
  by accident
* worker thread is now spawned per controller, rather than per-drive;
  i/o cannot be done concurrently by different drivers, only one
  i/o can be pending at any time
* simplify the command queue code, just sleep appropriately when
  !poll case, g/c 'async' code formerly needed, move the bio code
  from ed_mca.c to edc_mca.c:edc_bio()
* other misc cleanups
