Type: refactor
- per vls worker private pool of sessions
- deep copy of vls worker data structures on fork
- maintain a global, i.e., heap allocated, and lock protected pool of
elements that track sessions that are shared between workers (due to
forking).
Credit for uncovering the issue goes to Intel team contributing code to
VSAP (Ping, Yuwei, Shujun, Guoao).

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.

This is mostly used for quic in the case of a stream
creation (i.e. connect on an already established QUIC
session). We want do default parent_handle to INVALID
to be able to distinguish it from parent_handle = 0

Type: feature
* Adds the concept of a "connectable listener" : a session that
can be both connected and accepted on.
* vppcom_session_is_connectable_listener (fd) that tells if the fd
is a connectable listener
* vppcom_session_listener (fd) that gives you the listener's fd
that accepted the session (if any)
* vppcom_session_n_accepted (fd) that gives the number
of sessions a listener accepted.

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
switch.

-fno-common makes sure we do not have multiple declarations of the same
global symbol across compilation units. It helps debug nasty linkage
bugs by guaranteeing that all reference to a global symbol use the same
underlying object.
It also helps avoiding benign mistakes such as declaring enum as global
objects instead of types in headers (hence the minor fixes scattered
across the source).

Rename core data structures. This will break compatibility for out of
tree builtin apps.
- stream_session_t to session_t
- server_rx/tx_fifo to rx/tx_fifo
- stream_session.h to session_types.h
- update copyright

If an application worker calls listen on a session, vpp registers the
worker to the listener's work load balance group and, as new connections
are accepted, it may potentially push accept notifications to it.
There are however applications, like nginx, that on some workers may
never accept new connections on a session they've started listening on.
To avoid accumulating accept events on such workers, this patch adds
support for passive listeners. That is, workers that have started
listening on a session but then never call accept or epoll/select on
that listener.

- More fine tuning for multi-process applications.
- Experimental support for multi-thread apps. This is meant for app
whose threads are not vcl workers and the sessions are shared between
them.

Moves LDP logic that allows sharing of sessions between multi-process
app workers into a separate VCL shim layer. Also refactors LDP to use
the new layer.

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.

Ater this patch, vcl_test_client and vcl_test_server can work happily with

"-S" is to indicate TLS connection.
