Creates a new GSocket with the defined family, type and protocol.
If protocol is 0 (G_SOCKET_PROTOCOL_DEFAULT) the default protocol type
for the family and type is used.
The protocol is a family and type specific int that specifies what
kind of protocol to use. GSocketProtocol lists several common ones.
Many families only support one protocol, and use 0 for this, others
support several and using 0 means to use the default protocol for
the family and type.
The protocol id is passed directly to the operating
system, so you can use protocols not listed in GSocketProtocol if you
know the protocol number used for it.
