dahdi_cfg: add '-S <spanno>' and '-C <chan-ranges>' 

* dahdi_cfg -S <num>: only apply changes to span <num>.
* If span is analog (no 'span=<num>,<channels>,...' statement in
  system.conf), we need to set range: -C <channels>
* With the <basechan> and <channels> attributes in sysfs
  we easily configure each device on the fly.
  Simply run: dahdi_cfg -S <spanno> -C <basechan>+<channels>-1
  from udev script

Only apply changes to span no. \fISPAN\fR. For a digital span (with

Always configure every channel, even if it appears not to have changed.
