dahdi-base: Enable DAHDI to manage the reference counts for the board drivers.
Adds a struct module 'owner' member to the dahdi_span structure and updates
all the board drivers to set this member before registering the span. This
allows the core of dahdi to maintain the reference counts on the channels
itself.
(closes issue #10601)
