* The select()/deselect() hooks now actually call the socket's request_notification()

Browse Source 
and cancel_notification() functions.
* Completey dropped the old select code, as well as any R5 compatibility stuff. If
  we ever need it again, it's still in SVN history.
* The socket module was put in uninit_driver() for no reason.
* Minor cleanup.

Userland stack driver on_socket_event() callback mecanism implementation:
the driver start a kernel thread waiting on a port for
a NET_STACK_SOCKET_EVENT_MSG message, which come with a socket_event_data block.
The on_socket_event() mechanism stay in driver (kernelland) because it's
only there we can call kernel's notify_select_event() on BONE systems.
For non-BONE systems, we use our own r5_notify_select_event()
implementation, that could be moved into the userland net_server code,
but it'll have split (again!) the /dev/net/stack driver code...
