[L2TP]: Changes to existing ppp and socket kernel headers for L2TP
Add struct sockaddr_pppol2tp to carry L2TP-specific address
information for the PPPoX (PPPoL2TP) socket. Unfortunately we can't
use the union inside struct sockaddr_pppox because the L2TP-specific
data is larger than the current size of the union and we must preserve
the size of struct sockaddr_pppox for binary compatibility.
Also add a PPPIOCGL2TPSTATS ioctl to allow userspace to obtain
L2TP counters and state from the kernel.
Add new if_pppol2tp.h header.
[ Modified to use aligned_u64 in statistics structure -DaveM ]
