Joshua Colp has submitted this change and it was merged.
Change subject: res_pjsip_pubsub: Use common datastores container API.
......................................................................
res_pjsip_pubsub: Use common datastores container API.
This migrates res_pjsip_pubsub over to using the newly
introduce common datastores management API instead of using
its own implementations for both subscriptions and
publications.
As well the extension state data now provides a generic
datastores container instead of a subscription. This allows
the dialog-info+xml body generator to work for both
subscriptions and publications.
