Subject: Bluetooth: Add support for deferring RFCOMM connection setup
In order to decide if listening RFCOMM sockets should be accept()ed
the BD_ADDR of the remote device needs to be known. This patch adds
a socket option which defines a timeout for deferring the actual
connection setup.
The connection setup is done after reading from the socket for the
first time. Until then writing to the socket returns ENOTCONN.
