PPP: moved netif out of PPP control block

Browse Source 
Users might want to share a netif control block between an Ethernet
interface and a PPPoS interface (I want actually) in case PPP is just
used as redundancy if Ethernet is down (eg. PPPoS GPRS fail over).

Moved netif out of PPP control block in a similar way it is currently
done for Ethernet interfaces. Furthermore, this is a first step on
removing the "new/create/free/delete" API which is awful but currently
necessary to handle fail over from PPPoX to another PPPoX (eg. from PPoE
on xDSL to PPPoS on GPRS fail over) without free()ing the netif which
might be used on udp_sendto() or L2TP VPN links.
