Newer version of DAHDI hotplug scripts

A newer version of the scripts fully adapted to pinned spans:
* handle_device does not run dahdi_cfg.
* A separate UDEV rule script for that: span_config. Should also work
  for the non-pinned case.
* span_assignments, span_types: add actions 'auto' (manually enable all)
  and 'dumpconfig' (dump current status in the format of configuration
  file).
* Fixed name of span_types and span_assignments (no '-').
* spantype.conf renamed span-types.conf: configuration files do have a
  dash.
* Those two are useful programs, insstalled to /usr/sbin.
