Reviewed by: Julian Elischer / Jordan K. Hubbard
Changes are only effective, if NEW_SCSICONF is defined: 1) Added u_int16 quirks to struct scsi_link for device quirks. 2) Added void *devmodes to struct scsi_link for tape density modes. 3) Modified selectdev() to return first full match (with wildcard). With this patch all device dependent configuration is done in one place (scsiconf.c), while there were some specifications in st.c and some hardware dependent drivers (ie. ncr.c) before.
