1. bpf: Consistent usage of MARK_MAGIC constants …

   We currently use 8 bits of the packet mark to indicate that SNAT was
   already performed. That is more than necessary and inconsistent with
   other users of the packet mark for similar purposes.
   
   This commit changes that to only use 4 bits under the reserved
   MARK_MAGIC_HOST_MASK mask.
   
   Also worth noting that the IPsec comment here is incorrect:
   MARK_MAGIC_KEY_ID is currently unused so it wasn't conflicting with the
   SNAT mark.
