RPC wire format now includes client handle in all requests, and opcode and
client handle in all responses.
This simplies the daemon a little, and means that the directly-connected
serial client uses the same wire format as the daemon. The expense is some
redundant code in rpc_client and rpc_server to process (and throw away)
this extra stuff.
