Move from synchronous flushing of io and ctrl events from transports to
applications to an async model via a new session_input input node that
runs in interrupt mode. Events are coalesced per application worker.
On the one hand, this helps by minimizing message queue locking churn.
And on the other, it opens the possibility for further optimizations of
event message generation, obviates need for rx rescheduling rpcs and is
a first step towards a fully async data/io rx path.

Rename unused SESSION_IO_EVT_BUILTIN_TX to SESSION_IO_EVT_TX_MAIN and
leverage it for non-connected udp tx.
Non-connected udp sessions are listeners and are therefore allocated on
main thread. Consequently, whenever session queue node is not polling
main, tx events generated by external applications might be missed or
processed with some delay. To solve this, request that apps use
SESSION_IO_EVT_TX_MAIN tx events as opposed to SESSION_IO_EVT_TX and
send that to first worker as opposed to main.

Some upon apps(e.g. Nginx-quic) package it's several protocol buffers into a struct msg
which is a combination of gso_buffer and gso_size.
but if HostStack regardless the gso_size to the buffer and split the buffer with default mss,
that cause peer client failed on parsing the package.

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.

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.

Currently, mutlti-threads only support one dispatch thread and multiple
worker threads, eventually only dispatch thread is a vcl worker and can
interact with epoll.
This patch will register all threads as vcl worker, and then each
thread can interact with epoll now. Moreover, session migration also
supported, such as socket created in thread A and used (bind, connect
and etc.) in thread B.

Allow session cli filtering based on thread index, transport protocol,
session state and range of session pool indices. For instance
show session thread 1 proto tcp state ready range 0 20 verbose
Shows the session ids for the first 20 tcp sessions in thread 1 that are
in ready state.
To avoid excessive output that could reasult in the worker barrier being
held by the main thread for long periods of time, the session cli will
only output:
- session ids (verbose == 1) for a maximum of 50 sessions / worker
- verbose > 1 details for a maximum of 10 sessions

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.

In contrast to the closing notification, whereby a transport informs
the session layer that is beginning the closing procedure, this allows
transports to notify the session layer of the fact that the transport is
"fully" closed, i.e., it expects no more data.
Also:
- adds app closed state for sessions
- changes tcp to have it notify when an active close has finished
