Zach Brown ac259c82a0 scoutfs: allow interrupting client sends ...

Waiting for replies to sent requests wasn't interruptible.  This was
preventing ctl-c from breaking out of mount when a server wasn't yet
around to accept connections.

The only complication was that the receive thread was accessing the
sender's struct outside of the lock.  An interrupted sender could remove
their struct while receive was processing it.  We rework recv processing
so that it only uses the sender struct under the lock.  This introduces
a cpu copy of the payload but they're small and relatively infrequent
control messages.
