Half-open tls sessions are now tracked by the app worker and are cleaned
up only when tcp cleans up its half-open session, i.e., independent of
when the established tls context is allocated.

Use half-open sessions to track virtual circuit connection
establishment. These sesssions can only be allocated and freed by the
thread that allocates half-open connections (main). Consequently, they
can only be freed on half-open cleanup notifications from transports.
Goal is to simplify state tracking within the session layer but it's
also a first step towards allowing builtin apps to track and cleanup
outstanding connects.

By convention, connects segment manager will be first. Therefore it will
be the one with the first segment wherein lies the app's message queue.
Saves us the trouble of allocating it on first connect, if app started
by listening, and we no longer need to track if it's assignable to a
listener or if it can be removed.

We add interface address to the global lookup table, so we should
use it as the key when lookup listener. Otherwise, when multiple
threads listen on 0.0.0.0 (local scope disable), duplicate
listeners and sessions would be allocated but only one works.

trajectory trace has been broken for a while because we used to save the
buffer trajectory in a vector pointed to in opaque2. This does not work
well when opaque2 is copied (eg. because of a clone) as 2 buffers end up
sharing the same vector.
This dedicates a full cacheline in the buffer metadata instead when
trajectory is compiled in. No dynamic allocation, no sharing, no tears.

We should cleanup sessions in CREATED state when listener goes
down, otherwise they may use unpredictable sessions as listeners
later.

Under some timing conditions,VCL may receive CONNECTED/ACCEPTED
event before ADD_SEGMENT event.
Timing example:
2 threads call segment_manager_alloc_session_fifos() parallelly
Thread 1 Thread 2

try to alloc fifo =>failed |

sm read unlock |
| |
sm write lock |

sm write unlock |
| sm read lock
| |
| try to alloc fifo=>successful
sm read lock |
| sm read unlock
| |
| emit CONNECTED/ACCEPTED
emit ADD_SEGMENT event
|
sm read unlock
This commit move ADD_SEGMENT notification under the protection
of the write lock in some scenarios.

Current implementation may have timing issue:
1. The TCP 3-way-handshake is completed but the app is busy and
does not process the CONNECTED event.
2. VPP receive some data from peer and try to send a RX event to
VCL, but the fifo's client session index is not initialized yet.
So this event will be sent to incorrect session 0.

Experimental support for session layer interrupt mode. When enabled
(use-private-rx-mqs must be set) session queue node switches to
interrupt state when lightly loaded, i.e., no events and less than 1
vector/dispatch.
Because transport protocols require a periodic time update, when in
interrupt state the session queue node workers register a timerfd with
the unix-epoll-input node that when triggered signals, i.e., wakes up,
the queue node. Under light load, the timer is set to trigger every 1ms
whereas if no session is allocated, the worker moves to idle state and
the timeout is set to 100ms.

Add option to use per app private segments for app to vpp message
queues, as opposed to exposing internal message queues segment.
When so configured, internal message queues are still polled by the
session queue node but external app message queues are handled by a new
input node (appsl-rx-mqs-input) that runs in interrupt state. Signaling
of the node, when mqs receive new messages, is done through eventfds
epolled by worker epoll input nodes.
