Expose a close ntfn channel to all RPC handlers.
This commit modifies the RPC server such that all handlers now receive a channel which will be notified when a client disconnects. This notification can then be used to stop long-running operations early when a client disconnects. This capability was already present for websocket clients, but this commit exposes it to standard HTTP clients as well.
