[Rprotobuf-yada] playing with sockets.

[Romain François]

Hello,

I've added some code in trunk to start playing with sockets. It is 
absolutely not functional currently, and was more an excuse to learn 
about sockets programming in C.

I have based it on the protocol used by this rpc implementation: 
http://code.google.com/p/protobuf-rpc/ but I am not sure this is the 
best one to use.

The client side, as in "R invokes a remote rpc method" is not so hard I 
think: open a socket, write the input message and read the result 
message back.

The server side is going to be more tricky because I need to understand 
threads on top of sockets.

Romain
