- Add a set_provider_factory() method to server_state to allow injecting provider factory which will be called when the provider is loaded. Other related changes: - Implement to_string() helper method for id class. - Fix id ostream operator human readable id printing. - Pass victim client_service as an argument to provider::bf_abort() to allow passing victim context to custom provider. - Implement prev() helper method for seqno class. - Make server_state recover_streaming_appliers_if_not_recovered() public. In some recovery scenarios the method must be called outside of server_state internal code paths. - Add storage_service requires_globals() method. The storage service implementation may override this to return false if changing to storage service context does not require store/reset globals. - Change view final() to also require that the view status is not primary for the view to be final. Also change the method name to is_final() to avoid confusion with C++ final identifier. - Fixes to server state handling in disconnecting and disconnected states. - Keep TOI meta data over whole TOI critical section.
