MINOR: applet: Add an appctx flag to report shutdown to applets

There is no shutdown for reads and send with applets. Both are performed
when the appctx is released. So instead of 2 flags, like for
muxes/connections, only one flag is used. But the idea is the same:
acknowledge the event at the applet level.
