functions, build list at transport enable time.

TCP and (D)TLS clean up half-opens on main without a lock/barrier so
cleanup initiated from first worker, e.g., cut-throughs, can corrupt the
session pool.

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.

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.

To test using vcl test apps, first ensure all arp entries are properly
resolved and subsequently:

client: vcl_client -p dtls <server-ip> 1234 -U -N 2000000 -T 1460 -X

This is an af_unix socket alternative to the binary api. To enable it,
add use-app-socket-api under session stanza in startup.conf. When the
socket api is enabled, attachments through the binary api are disabled.
The socket api only works with memfd fifo segments, i.e., shm segments
are not supported.
