Pause the mux channel while waiting for reply from aynch callbacks.

Prevents misordering of replies if new requests arrive while waiting.

Extend channel open confirm callback to allow signalling failure
conditions as well as success. Use this to 1) fix a memory leak, 2)
start using the above pause mechanism and 3) delay sending a success/
failure message on mux slave session open until we receive a reply from
the server.
