Type: feature
This changes the behavior of both API calls
APPLICATION_TLS_CERT_ADD & APPLICATION_TLS_KEY_ADD
certificates and keys aren't bound to an app, they are
passed to it via connect / listen using the message
queue.
This should be followed by a per protocol (QUIC/TLS)
crypto_context store to save devrived structs

Type:refactor
Moves connect, disconnect, bind, unbind and app detach to message
queue from binary api. Simplifies app/vcl interaction with the session
layer since all session control messages are now handled over the mq.
Add/del segment messages require internal C api changes which affect all
builtin applications. They'll be moved in a different patch and might
not be back portable to 19.08.

Type: feature
This can be used to forcefully close a session. It's only available to
builtin applications for now. Transports must support the reset api
otherwise normal close is used.

Type:fix
Transports like tcp may notify session layer of a close but they may
defer the connection's deletion (e.g., tcp time-wait). During that time,
transports may still want to send packets. So, unless the session has no
transport (transport-deleted state), allow the transport to send.

Type:fix
Freeing mq messages in vpp (producer), if enqueueing fails, invalidates
consumer assumption that messages can be freed without a lock.

Problems Addressed:
- Contention of cursize by producer and consumer.
- Reduce the no of modulo operations.
Changes:
- Synchronization between producer and consumer changed from cursize
to head and tail indexes
Implications: reduces the usable size of fifo by 1.
- Using weaker memory ordering C++11 atomics to access head and tail
based on producer and consumer role.
- Head and tail indexes are unsigned 32 bit integers. Additions and
subtraction on them are implicit 32 bit Modulo operation.
- Adding weaker memory ordering variants of max_enq, max_deq, is_empty
and is_full Using them appropriately in all places.
Perfomance improvement (iperf3 via Hoststack):
iperf3 Server: Marvell ThunderX2(AArch64) - iperf3 Client: Skylake(x86)
~6%(256 rxd/txd) - ~11%(2048 rxd/txd)

Instead of allocating pairs of message queues per cut-thru session and
having the applications map them, this uses vpp as an io event message

In case of multi process apps, after forking, the parent may decide to
close part or all of the sessions it shares with the child. Because the
sessions have fifos allocated in the parent's segment manager, they must
be moved to the child's segment manager.

Disconnect transport even if tx fifo is not empty and have transport
deal with the problem. In case of tcp, add timer to fin_wait_1. If it
expires and we're still in established state, cleanup but only after
waiting for session tx events to cleanup.
