Let the device thet gets an atapibus attached specify how to kill pending transfers by giving a function pointer. The old method always called wdc specific code.

Merge scsipi branch in the mainline. This add support for ATAPI devices (currently only CD-ROM drives on i386). The sys/dev/scsipi system provides 2 busses to which devices can attach (scsibus and atapibus). This needed to change some include files and structure names in the low level scsi drivers.

- DMA code cleanup: pciide_dma_finish() doesn't stop/unload the current DMA op if an IRQ was not detected, unless the force flag was given. Use this to detect if the IRQ was for us (closer to shared IRQ for controllers which don't have their own IRQ handler in pciide.c) and to poll for DMA xfer. Also makes the timeout recovery code simpler. - ATAPI cleanup: don't call controller-specific functions from atapiconf.c (wdc_*), so that it's possible to attach an atapibus to something else than a wdc/pciide (Hi Lennart :). Overload struct scsi_adapter with struct atapi_adapter, defined as struct scsi_adapter + atapi-specific callbacks. scsipi_link still points to an scsi_adapter, atapi code casts it to atapi_adapter if needed. Move atapi_softc to atapiconf.h so that it can be used by the underlying controller code (e.g. atapi_wdc.c). Add an atapi-specific callback *atapi_probedev(), which probe a drive in a controller-specific way, allocate the sc_link and fills in the ataparams if needed. It then calls atapi_probedev() (from atapiconf.c) to do the generic initialisations and attach the device. - While I'm there merge and centralise the state definitions in atavar.h. It should now be possible to use a common ata/atapi routine to set the drive's modes (will do later).

add support for an ATAPI attachment for 'sd'. fix 'cd' driver's NCD_SCSI bogosity (was using testing wrong macro!) clean up in various ways: * make common atapi_mode_{sense,select}() functions. * put ATAPI data structures in more sensible headers, split up by device type. * include headers a bit more carefully. * pass flags to attachment-specific cd functions, and use them. * get rid of SCSI bits in scsipi_base.h's scsipi_make_xs(), move them into the correct place in scsi_base.c. * fix minor typo in struct name in scsipiconf.h (which was apparently never used except in a #define later in the same file). * use __attribute__ to force 4-byte alignment for xs command store, so that architectures trying to bus_space_write_multi_N() (where N > 1) that data to a controller won't lose. * clean up a few comments in typos, and make a few #defines easier to understand/maintain. * rename cd_link.h to cdvar.h (via repository copy). This is exactly what a 'var' file is supposed to be.

Cancel active transfers on aic/wdc detach. Also makes LS-120 drive works for me again.
