NetBSD/sys/dev/scsipi/cd_atapi.c
cgd 3b207eaf83 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.
