	src/sys/dev/ic: wdc.c
	src/sys/dev/scsipi: atapi_wdc.c

Log Message:
Implement asynchronous channel reset.
Use this to reset the channel before doing a dump, instead of the hack in
  wdc_exec_xfer() based on C_POLL. This hack was causing problems on
  controllers with a shared queue, because we now can have C_POLL set during
  concurent channels probes (problem found and analysed on sparc64 by
  Martin Husemann).
This should even make core dumps marginally more reliable on ATA drives.
