Replace whitespread (mis)use of snat_session_key_t by proper function
arguments where applicable and inline functions to calculate hash keys
instead of using structs for that. Make all hash tables use same network
byte order port so that there is no longer a discrepancy between static
mappings using host byte order while in2out/out2in tables using network
byte order.

By storing thread and session index in hash table we are able to skip
multiple hash lookups in multi-worker scenario, which were used for
handoff before. Also, by storing sesion index in vnet_buffer2, we can
avoid repeating the lookup after handoff.

This fixes a situation where long-lived inactive session blocks LRU
list. Solution is to have multiple LRU lists based on session type.
This helps because session timeout is same for all sessions of same
type.

With port overloading, port is no longer a scarce resource and there
is no need to limit connections per internal IP. This saves one hash
insert in slow path.

Maintain a global session LRU allowing reuse of expired session instead
of relying on a scavenging mechanism to periodically walk sessions.
Whenever a new session is being allocated in slow path, also attempt to
free an expired session from global LRU list.

An unknown proto packet can be processed as UDP with destination port
rewriting which breaks the original packet.
With this commit, stop processing unknown proto packets after
nat44_ed_out2in_unknown_proto() execution.

Patch changes the behavior of session scavenging and fixes multiple
nat issues. Allows proper session clearing and removes issue with lingering sessions
in session db. Patch also updates and fixes CLI/API calls for better readability
of session state metrics. Fixes security issue that would allow attacker to
reuse timed out session in both directions (in2out/out2in).

In endpoint dependent mode, when a session at the head of a user
LRU is reused, if the IP protocol for that session was unknown (any
other than tcp, udp, or icmp), the attempt to delete the session
mapping from the in2out bihash was not using the same key that was
used when the mapping was added. This would cause the deletion of
the mapping to fail. If packets arrive later which match the original
session, the search for the session key would succeed when it should
have failed and the session, which is now associated with a different
pair of endpoints, may end up being updated when it should not be.
Update the key generation when reallocating an existing session to
do the right thing if the session is for an unknown protocol.
Also update format_nat_session() for unknown protocols so that
'vppctl show nat44 session detail' will display the protocol
correctly. In endpoint dependent mode, the IP protocol is stored in
the port field on a session if the protocol is unknown. The value
is stored in host byte order, but the format function was swapping
the bytes before writing the protocol.
