Kevin Harwell	b31ac83900	mwi: Update the MWI core to use stasis_state API ... ** Note ** This patch is meant to be the minimum needed in order for the MWI core to use the now underlying stasis_state module. As such it does not completely remove its reliance on the stasis_cache. Doing so has allowed current consumers to not have to change, and update those code paths for this patch. When time allows, subsequent patches can/will be made to those consumers to take advantage of some of the new MWI API included here. Thus, eventually and ultimately removing MWI dependency on the stasis_cache. ** End Note ** This patch makes it so the MWI core now takes advantage of the new stasis_state API. Consumers of MWI should no longer need to depend upon stasis topic pooling, and the stasis cache directly. Similar functionality and implementation details have now been pushed into the stasis_state module. However, all MWI state should be accessed via the MWI API itself. As such a few new methods, and constructs have been added to the MWI core that facilitate consumer publishing, subscribing, and iterating over MWI state data. * ast_mwi_subscriber * Created via ast_mwi_add_subscriber, a subscriber subscribes to a given mailbox in order to receive updates about the given mailbox. Adding a subscriber will create the underlying topic, and associated state data if those do not already exist for it. The topic, and last known state data is guaranteed to exist for the lifetime of the subscriber. * ast_mwi_publisher * Before publishing to a particular topic a publisher should be created. This can be achieved by using ast_mwi_add_publisher. Publishing to a mailbox should then be done using one of the MWI publish functions. This ensures the message is published to the appropriate topic, and the last known state is maintained. * ast_mwi_observer * Add an observer in order to watch for particular MWI module related events. For instance if a submodule needs to know when a subscription is added to any mailbox an observer can be added to watch for that. * other * Urgent message count is now part of the published MWI state object. Also state can be iterated over using defined callbacks. ASTERISK-28442 Change-Id: I93f935f9090cd5ddff6d4bc80ff90703c05cf776	7 years ago
