c1082cee65 Fixed comedi_get_cmd_generic_timed() by adding a chanlist_len 
parameter.  Old version is still available in library, thanks to the
magic of the version_script.

4cdf1b09a9 Added choose_clock and choose_routing demo programs. Synced comedi.h 
with comedi.  Made dio demo simply configure the line direction based
on the command line argument.

c17577318d 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.

761ffc3e90 Applied (slightly modified) patch from David MacMahon 
<davidm -at- astro -dot- berkeley -dot- edu>.
Reports specific error string (strerror(errno)) if comedi_open fails (I
changed the format slightly from David's).
Displays subdevice flags as a hexadecimal number.

998c091e1e doing a retry for the preload write is useless, since the command 
hasn't started yet.  Print a useful error message and exit instead.
