Avoid constantly re-mapping a listener's first segment when all its
sessions are closed.

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

Add an ALWAYS_ASSERT (...) macro, to (a) shut up coverity, and (b)
check the indicated condition in production images.
As in:
p = hash_get(...);
ALWAYS_ASSERT(p) /* was ASSERT(p) */
elt = pool_elt_at_index(pool, p[0]);
This may not be the best way to handle a specific case, but failure to
check return values at all followed by e.g. a pointer dereference
isn't ok.

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

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.
