Hi,

In order to implement HFP profile correctly the gateway needs to know 
address off the the HF device before accepting the connection. Currently 
there is no way to check the address without calling accept(). This 
patch creates a socket option which can be used change the behavior of 
the socket. Server still calls accept() but the actual connection setup 
will be done only after calling recv() for the first time. In between 
the server can use other getsockopts to get the needed information.

I also attached patch against rctest.c as an example how test this feature.

Waiting for comments :)
