> Allow IPC clients to perform the IPC handshake before the first RPC is invoked

> Currently, the first RPC must complete before any subsequent RPCs may be
> invoked using the same Transceiver instance. The reason for this behavior is
> that the IPC client-server handshake must be performed before any requests
> can be exchanged. So while the first RPC is being invoked, all other threads
> using the same Transceiver instance will block. The goal of this enhancement
> is to allow clients to perform a handshake with the server _before_ any RPCs
> are invoked to avoid blocking any threads once the Transceiver is put into
> service.
> I have a patch for review that I think will enable clients to perform the
> handshake before the first RPC is sent. The changes consist of:
> * Modification to the Responder to handle a request that contains only a
> handshake (without an RPC)
> * Addition of overridden SpecificRequestor.getClient(...) methods that take
> an boolean indicating whether the handshake should be performed immediately
> upon initialization of the Requestor
> * Unit test which is essentially the same as the test I wrote for AVRO-1001,
> but it uses a pre-RPC handshake rather than invoking the add(...) RPC to
> perform the handshake
