Hallo!

The attached patch makes the vnet-module working for i386
and x86_64. (I had no other systems for testing)
(My patch from 6.6.2007 is included)

 - x86_64: the x86-64 kernel has __ARCH_WANT_SYS_SOCKETCALL
   defined, but has no socketcall. Replacing the _syscall's
   to a working one.

 - moves the "skb_pull" function from kernel to skb_util.c
   because pulling in the data will rise a "BUG_ON" in the
   kernel. The kernel-function does not allow to pull into
   the payload!

 - the skb_buff is not always possible to modify a received
   buffer to send it again to the network.
   (vnet_forward.c and etherip.c) The code now work's..
   I think with no or less time-penalty.


Summary:
Solved:
  With this patch the vnet-module is working on i386 and x86_64,
  including peering-option.   (except the following "open")


Open:
 - Vnet's only with security-option "none" are working.
 - The module-option "vnet_encaps" is ignored, always "udp" is used.
