This is a port of the functionality in the wctdm24xxp driver to support power
savings modes. Specifically, if the the network side of a BRI spans deactivates
the span to save power, the B410P previously automatically activated it again.
Now, if persistentlayer1=0 module parameter is set, the span will be allowed to
stay deactivated until layer two has a message to send on the dchannel.
This patch does not change any of the default behavior of the B410P driver and
the defaults for the persistentlayer1 option is inconsistent with that of the
B400M modules in the wctdm24xxp driver.

[ Minor formatting, exposed the persistentlayer1 as module parameter, changed
defaults for teignorered, alarmdebounce, and persistentlayer1 to match current
defaults in wcb4xxp driver ]

Increasingly, spans are implemented by devices that support more than a
single span. Introduce a 'struct dahdi_device' object which explicitly
contains multiple spans. This will allow a cleaner representation of
spans and devices in sysfs since order of arrival will not determine the
layout of the devices. This also gives the core of dahdi a way to know
the relationship between spans.
This generalizes similar concepts that were previously xpp specific. The
conversion of the xpp code was almost entirely done by Oron and Tzafrir.

The 'pdev' member already contained a pointer to what 'dev' was pointing
to. Also ensure most of the changed lines are under 80 characters.
There are two lines that are were too deeply nested to do anything
sensible.

This needs some more testing before it's on by default. If the card is
otherwise functioning, these messages may be confusing to the user. If
the card is not functioning, the driver can be reloaded with debug to
check for this condition.
