Inspector+LibCore+rpcdump: Rework the RPC stuff to be request/response

Browse source 
RPC clients now send JSON-encoded requests to the RPC server.
The connection also stays alive instead of disconnecting automatically
after the initial CObject graph dump.

JSON payloads are preceded by a single host-order encoded 32-bit int
containing the length of the payload.

So far, we have three RPC commands:

    - Identify
    - GetAllObjects
    - Disconnect

We'll be adding more of these as we go along. :^)
