for un-deletable, un-editable calendar source, just return TRUE in the
get_is_read_only method of the backend, and don't implement at all
create_object, modify_object, remove_object methods. Just make them
return an error code.

you should implement all, except those that imply modifications, like
the 3 listed above, add_timezone, remove_calendar, and I think that's
all. The rest should all be implemented.

It is not clear to me yet neither how to add those backends to the
source selector. Probably in the new-calendar-druid we are going to
write.
