When 'Symmetric' flag is enabled, it will sort the addresses
and hence, same flow hash will be calculated on both directions.

Add the VNET_FEATURE_ARC_ORDER macro, which allows specification of
bulk order constraints. Here's an example:

VNET_FEATURE_ARC_ORDER(ip4_unicast_arc_order, static) = {
  .arc_name = "ip4-unicast",
  .node_names = VNET_FEATURES ("ip4-flow-classify",
                               "ip4-inacl",
                               "ip4-source-check-via-rx",
                               "ip4-source-check-via-any",
                               "ip4-source-and-port-range-check-rx",
                               "ip4-policer-classify",
                               "ipsec4-input",
                               "vpath-input-ip4",
                               "ip4-vxlan-bypass",
                               "ip4-not-enabled",
                               "ip4-lookup"),
};

Simply list feature nodes in the desired order, and you're
done. Multiple macro instances per are are fine / expected /
tested.

Under the covers: generate "a before b" tuples by chain-dragging
across the ordered list. No need to touch existing per-feature
constraints.

Fixed a long-broken "you lose!" error message.

ip4-input: fix prefetch data issue for tunnel decap cases

There are two reasons to modify the existing code ip4_input_inline.

1. For many tunnel decap cases, inner ip header or its part is possible
in the second cacheline, not first cacheline only after the field "data",
and this will cause data cache miss once the second cacheline is needed
to access. e.g vxlan-gpe.
2. For most of cases, "data" is the starting address of ethernet
header, not IP header. The existing code causes misunderstanding
from code readability perspective.
