- Add a new DRVCTLCOMMAND ioctl to /dev/drvctl. This is a generic
"execute a command" ioctl that takes a dictionary as an argument
(specifying the command and arguments) and returns a dictionary
with the results (error code, optional error message, optional
result data).

- Define and implement a "get-properties" command for DRVCTLCOMMAND
that returns the properties dictionary of the specified device.

- Add a -p flag to drvctl(8) to fetch and display the properties of
the specified device.

This is a great example of how to use prop_dictionary_sendrecv_ioctl().

Move WARNS=3 to the Makefile.inc, and add a little const to the remaining
programs that did not compile before.

add the -t option that modifies -l behaviour to recursively scan for
child devices and print them in tree format:

$ drvctl -lt usb0
uhub0
uhub6
uhidev0
ukbd0
wskbd1
uhidev1
ums0
wsmouse1
uhid0
ubt0

add an optional argument to the -p flag that lets you extract specific
property values from the command-line:

$ drvctl -p wd0 disk-info/geometry/cylinders-per-unit
620181
$ drvctl -p wd0 device-driver device-unit
wd
0
$ drvctl -p wd0 nonexistent || echo "not found"
not found

Document -n.

Add -n to usage. Now it just needs to be documented.

Bump date for previous. Remove trailing whitespace.

Add flag -n to suppress the first column of drvctl -l output.

If drvctl -l is used without argument, print the root device nodes.
