commit 680f3e1d1d827ae3e3aad9e501ad30b7c15c1a00

    dahdi_registration: adapt to pinned-spans
    
    * If xpp.dahdi_autoreg parameter is 'Y' -- Skip actuall registration.
    * If dahdi.auto_assign_spans is '0' and there's no /etc/dahdi/pinned-spans.conf
      Than use 'span_assignments auto ...' to assign device spans.
    * Since dahdi_registration iterate in correct xpp_order, the span
      assignment logic provides migration path for users who did not
      generate their pinned-spans.conf configuration yet.
