Module Name:    src
Committed By:   bouyer

Modified Files:
        src/sys/dev/ata: ata.c ata_wdc.c atavar.h
        src/sys/dev/ic: wdc.c wdcvar.h
        src/sys/dev/scsipi: atapi_wdc.c

Log Message:
Add
struct ata_xfer *active_xfer
to ata_queue. Now the active xfer isn't the head of the queue any more,
this makes a few things easier (this will also help for tagged queuing
support).
Remove the WDCF_ACTIVE flag, test active_xfer != NULL instead.
clean up wdc_free_xfer() and kill_xfer().
Clean up wdc_reset_channel(), and make it issue a ATAPI_SOFT_RESET if the
active command is ATAPI.
In wdc_atapi_get_params(), use AT_WAIT | AT_POLL for ATAPI_SOFT_RESET,
so that we'll use tsleep() instead of delay().
In wdc_atapi_start(), call wdc_dmawait() at the right place.
