Kenneth D. Merry 21b6ee96fc Update chio(1) and ch(4) to support reporting element designators. ... This allows mapping a tape drive in a changer (as reported by 'chio status') to a sa(4) driver instance by comparing the serial numbers. The designators can be ASCII (which is printed out directly), binary (which is printed in hex format) or UTF-8, which is printed in either native UTF-8 format if the terminal can support it, or in %XX notation for non-ASCII characters. Thanks to Hiroki Sato <hrs@> for the explaining UTF-8 printing and example UTF-8 printing code. chio.h: Modify the changer_element_status structure to add new fields and definitions from the SMC3r16 spec. Rename the original CHIOGSTATUS ioctl to OCHIOGTATUS and define a new CHIOGSTATUS ioctl. Clean up some tab/space issues. chio.c: For the 'status' subcommand, print the designator field if it is supplied by a device. scsi_ch.h: Add new flags for DVCID and CURDATA to the READ ELEMENT STATUS command structure. Add a read_element_status_device_id structure for the data fields in the new standard. Add new unions, dt_or_obsolete and voltage_devid, to hold and address data from either SCSI-2 or newer devices. scsi_ch.c: Implement support for fetching device IDs with READ ELEMENT STATUS data. Add new arguments to scsi_read_element_status() to allow the user to request the DVCID and CURDATA bits. This isn't compiled into libcam (it's only an internal kernel interface), so we don't need any special handling for the API change. If the user issues the new CHIOGSTATUS ioctl, copy all of the available element status data out. If he issues the OCHIOGSTATUS ioctl, we don't copy the new fields in the structure. Fix a bug in chopen() that would result in the peripheral never getting unheld if chgetparams() failed.
