acl-plugin: change the src/dst L3 info in 5tuple struct to be always contiguous with L4 data
Using ip46_address_t was convenient from operational point of view but created some difficulties dealing with IPv4 addresses - the extra 3x of u32 padding are costly, and the "holes" mean we can not use the smaller key-value data structures for the lookup. This commit changes the 5tuple layout for the IPv4 case, such that the src/dst addresses directly precede the L4 information. That will allow to treat the same data within 40x8 key-value structure as a 16x8 key-value structure starting with 24 byte offset.
