Note: tcsh(1) has a MK_TCSH=no test, so this should be a separate
package, which requires pre-install/post-install scripts, to be
added later.

Off by default, build behaves normally.
WITH_META_MODE we get auto objdir creation, the ability to
start build from anywhere in the tree.
Still need to add real targets under targets/ to build packages.

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.

rather than a voltag name, do not set the CESR_VOLTAGS flags in the
CHIOGSTATUS command requesting the current status. As voltags are an
optional feature that must be handled as "reserved" by media changers
not implementing the feature, always setting CESR_VOLTAGS resulted in
the command being aborted with an `Invalid field in CDB', and
consequently the "chio return" failed, for media changers that do not
support voltags.

o __P has been reoved
o Old-style K&R declarations have been converted to new C89 style
o register has been removed
o prototype for main() has been removed (gcc3 makes it an error)
o int main(int argc, char *argv[]) is the preferred main definition.
o Attempt to not break style(9) conformance for declarations more than
they already are.
Approved by: arch@, new style(9)
- The ability to specify elements by volume tag instead of their actual
physical location. e.g., instead of:
chio move slot 3 slot 4
you would now use:
chio move voltag FOO slot 4
- The ability to return an element to its previous location, as specified
by the source element. e.g., instead of:
chio move drive 0 slot 4
you would now use:
chio return drive 0
or
chio return voltag FOO
These features will obviously only work with changers that support volume
tags and/or source element IDs. chio(1) should fail gracefully if the user
attempts to use these new features and the source element ID or volume tag
are not found.
