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.

dahdi_registration [-v] [-s sortorder] [-R] [on|off]
=head1 DESCRIPTION
@ -105,6 +134,12 @@ Span registration should generally always succeed. Span unregistration may
fail if channels from the span are in use by e.g. asterisk. In such a case
you'll also see those channels as '(In use)' in the output of lsdahdi(8).
dahdi_registration is intended to be used when the xpp module parameter
B<dahdi_autoreg> is false (and implicitly: when the dahdi module parameter
B<auto_assign_span> is true.
If dahdi_autoreg is true, the program will normally do nothing.
=head2 Parameters
off -- deregisters all XPD's from dahdi.

=over
=item -v
verbose output.
=item -R
Force operations (on/off) even if the module parameter B<dahdi_autoreg>
for xpp is enabled (which makes this program unneeded).

The sort order to use.
