    unixsocket: introduce a version/datacontrol header (2byte)
    The ALT TC/Superchannel switch requires a seperate side channel. By introducing a header this
    can be done in a clean way. So every packet gets
    - 1 byte version
    - 1 byte data or control

    unixsocket: make socket connection fault tolerant
    When the l2tpd is killed, the unix socket will permanently loose the connection,
    even if l2tpd is restarted the connection is still blocked. This commit adds
    some fault tolerance mechanisms to automatically reconnect the socket as soon
    as it is available again.

    unixsocket: Ensure superchannel is disabled for new connections
    When the BSC is shut down or disconnected it may happen that the
    SIU stays in superchannel mode, while the BTS is falling back
    into its normal communication mode. This causes a permanent
    link failure because the SIU is still trying to reconnect on
    the superchannel.
    This patch ensures that for every new connection the superchannel
    is taken down by default. If the connection was still good, SIU
    and BTS will switch back to normal mode together. If not. The
    SIU will switch back alone while the BTS is already switched
    back by itsself.
