registration-order: Added dahdi_auto_assign_compat

Maintains the original registration order as was before span
assignments. Should allow seemless trannsition to
dahdi.auto_assign_spans=0

* The idea:
  - We stop handling in udev the case of missing
    /etc/dahdi/assigned-spans.conf
  - Instead we rely on "registration_time" dahdi_device attribute from
    DAHDI-linux
  - Then, we can sort the devices and assign their spans in
    /etc/init.d/dahdi
* Mechanics:
  - From /etc/init.d/dahdi, we run a new 'dahdi_auto_assign_compat'
    script (after "waitfor_xpds" etc.)
  - In this script we "auto" assign spans of non-Astribank devices
  - In the end of the script we run "dahdi_registration" which
    does the same for Astribank devices.
