Force pacing for fast retransmit to avoid bursts of retransmitted
packets.

Adds tx pacing infrastructure for transport protocols that want to use
it. Particularly useful for connections with non-negligible rtt and
constrained network throughput as it avoids large tx bursts that lead to
local interface tx or network drops.
By default the pacer is disabled. To enabled it for tcp, add tx-pacing
to tcp's startup conf. We are still slightly inefficient in the handling
of incoming packets in established state so the pacer slightly affect
maximum throughput in low lacency scenarios.

- adds session layer support for datagram based protocols
- updates udp to work in pure connectionless and datagram mode. The
existing connected mode is now 'accessible' for apps as a dummy UDPC,
as in, connected udp, protocol.
- updates udp_echo, echo client, echo server code to work in datagram
mode.

It consists of two main parts. First, add an application transport type
whereby applications can offer transport to other applications. For
instance, a tls app can offer transport services to other applications.
And second, a tls transport app that leverages the mbedtls library for
tls protocol implementation.

- compute session type out of transport and network protos
- make session, session lookup and session queue code network protocol
agnostic
This does not update the session layer to support non-ip network layer
protocols

- Cleanup half-open connections and timers on the right thread
- Ensure half-open connection and transport endpoint pools are thread safe
- Enqueue TX events to the correct vpp thread in the builtin client
- Use transport proto in transport connections instead of session type
