demo/cmd: limit options.n_chan to N_CHANS
...
If the '-n' option sets options.n_chan to something higher than N_CHANS
(256), reduce it to avoid overrunning the chanlist[] array.

Check the subdevice actually exists and that it claims to support 'read'
commands (SDF_CMD_READ subdevice flag set), bailing out early if not.

Check return value of prepare_cmd_lib() and exit if less than 0.

instead of stdout.

demo/cmd: default to the 'read' subdevice instead of subdevice 0
...
If the '-s' option has not been specified, default to using the current
'read' subdevice if there is one instead of defaulting to subdevice 0.
Fall back to using subdevice 0 if there is no 'read' subdevice.

demo: update demo programs to set read or write subdevice
...
Attempt to make the streaming command demos work if the specified
subdevice is not the default 'read' or 'write' subdevice (depending on
the direction of the command).
This uses the new comedi_set_read_subdevice() and
comedi_set_write_subdevice() functions.
Changing the read or write subdevice is currently supported only by the
Linux "in-tree" version of Comedi since kernel version 3.19.

parameter. Old version is still available in library, thanks to the

Applied patch from David MacMahon <davidm -at- astro -dot- berkeley -dot- edu>.
...
Adds physical units support to comedilib demo programs.
I changed one of the format strings to help line up values better in the
'cmd' example.
