Make the array of labels in struct ovs_key_ct_label an union, adding a
u32 array of the same byte size as the existing u8 array.  It is
faster to loop through the labels 32 bits at the time, which is also
the alignment of netlink attributes.

Receiving change events before the 'new' event for the connection has
been received can be confusing.  Avoid triggering change events for
setting conntrack mark or labels before the conntrack entry has been
confirmed.

The conntrack lookup for existing connections fails to invert the
packet 5-tuple for NATted packets, and therefore fails to find the
existing conntrack entry.  Conntrack only stores 5-tuples for incoming
packets, and there are various situations where a lookup on a packet
that has already been transformed by NAT needs to be made.  Looking up
an existing conntrack entry upon executing packet received from the
userspace is one of them.

This patch fixes ovs_ct_find_existing() to invert the packet 5-tuple
for the conntrack lookup whenever the packet has already been
transformed by conntrack from its input form as evidenced by one of
the NAT flags being set in the conntrack state metadata.
