use the generic per plugin defines and its init and exit functions and
then provide methods to register and unregister the operations.
Please keep in mind that in theory we can load more than one of these
phonebook "drivers".
All (and I mean all) plugins in bluetoothd and obexd are treated the
same. It is up to their init and exit routines to do the job. This
allows us to have a generic plugin framework and not do invent it over
and over again.
Did anyone converted the picture from the whiteboard at the meeting into
some written details.
