Russ Cox 841d71b5c6 9pserve: fix races causing assert(c->nmsg == 0) to fail. 
1. Could happen that connoutthread sends c->outq a nil
just before the regular input handler sends c->outq a real message.
When the connoutthread gets the nil it will free c->outq,
leaving the real message unprocessed.

2. Could happen that the outputthread writes a message
body to the remote 9P server and then a response comes
in and then the connection gets torn down, all before the
outputthread manages to call msgput(m).
Thanks to David Swasey for identifying this scenario.

Also change yield() loop into explicit communication.

Also remove dead code involving hungup queues.
