Separate sniffing from session initialization
This avoid lengthy/duplicate sniffing for drm plugins when a decrypt session is opened o The change is backward compatibile in that no update is required for existing drm plug-ins if they do not plan to provide separate sniffer/extractor related-to-bug: 5725548 Change-Id: I7fc4caf82d77472da4e2bc7b5d31060fb54fd84c
