L2TP: Add session specific allocation function

Separate session allocation from the rest of tunnel allocation
operations. This implies a few extra modifications:

  * Store destination address of the SCCRQ message in the
    connection structure (and rename the "addr" field to
    "lac_addr" for consistency). This information is required
    for allocating the session.

  * No more PPP information in log prefix: with session
    multiplexing, tunnels are no longer tied to a single PPP
    session, so there is no struct ppp_t to pass as parameter
    to the log_switch() function.

Session allocation is currently still done inside
l2tp_tunnel_alloc(). It should rather be done at session
establishment once tunnel/session separation will be terminated.
