Flow key handling changes:
- Add VLAN header array in struct flow, to record multiple 802.1q VLAN
headers.
- Add dpif multi-VLAN capability probing. If datapath supports
multi-VLAN, increase the maximum depth of nested OVS_KEY_ATTR_ENCAP.
Refactor VLAN handling in dpif-xlate:
- Introduce 'xvlan' to track VLAN stack during flow processing.
- Input and output VLAN translation according to the xbundle type.
Push VLAN action support:
- Allow ethertype 0x88a8 in VLAN headers and push_vlan action.
- Support push_vlan on dot1q packets.
Use other_config:vlan-limit in table Open_vSwitch to limit maximum VLANs
that can be matched. This allows us to preserve backwards compatibility.
Add test cases for VLAN depth limit, Multi-VLAN actions and QinQ VLAN
handling

Add logics to detect the max level of nesting allowed by the
sample action implemented in the datapath.
Future patch allows xlate code to generate different odp actions
based on this information.

'ct_state' currently only needs 8 bits, so we can make room for a new
CT field introduced in the next patch.

With eight 32-bit registers, we can only store two IPv6 addresses, which is
pretty tight.

This fixes several tests that failed on big-endian systems because "union
flow_in_port" overlays an ofp_port_t and odp_port_t and in some cases it
is not easy to determine which one is in use.
This commit also fixes up a few places where this broke other code.
