Wez Furlong 6193331a4a http/xfer injection: grab Activity handle for duration of request
I noticed that we weren't grabbing the Activity handle for injection
requests.  Doing so allows us to reject a request that comes in
while we are shutting down the service, rather than accept it to
have it potentially dropped as we shut down.

I also realized that we need to make the xfer injection handler
match the same set of rules for the http injection handler, so
this commit refactors that logic to reuse it in both places.
