      mod_ssl: return non ambiguous value in ssl_callback_SessionTicket() for
encryption mode (we used to return 0, OpenSSL documents returning 1 instead).

Practically this does not change anything since OpenSSL will only check for
>= 0 return value (non error) for encryption mode (the other possible return
values are only relevant for decryption mode).

However the OpenSSL documentation for SSL_CTX_set_tlsext_ticket_key_cb()
states:
"
The return value of the cb function is used by OpenSSL to determine what
further processing will occur. The following return values have meaning:

    This indicates that the ctx and hctx have been set and the session can

      event: Avoid possible blocking in the listener thread when shutting down
connections. PR 60956.

start_lingering_close_nonblocking() now puts connections in defer_linger_chain
which is emptied by any worker thread (all atomically) after its usual work,
hence any possibly blocking flush and lingering close run outside the listener.

The listener may create a dedicated worker if it fills defer_linger_chain or
while it's not empty, calling push2worker with a NULL cs.

The state machine in process_socket() is slighly modified to be able to enter
with CONN_STATE_LINGER directly w/o clogging_input_filters to interfer.

New abort_socket_nonblocking() allows to reset connections when nonblocking is
required and we can't do much about the connection anymore, nor we want the
system to linger on its own after close().

Many thanks to Stefan Priebe for his heavy testing on many event's changes!

event: use atomics for *timeout_queue->total since it's updated concurrently,
and move TO_QUEUE_*() macros to functions.


event: add/remove from/to the pollset outside of the critical sections.

We don't need external locking since it's created with APR_POLLSET_THREADSAFE,
hence reduce those sections to the lowest cycles possible.

A spinlock may be interesting instead of the mutex now, we won't block and the
TO_QUEUE_*() and process_timeout_queue() operations are fast...



event: follow up to r1762701: update log tag.

event: avoid unnecessary listener/polling wake ups (context switches) by using
apr_pollset_wakeup(), when implemented, to signal the listener according to the
next timers or timeout queues expiry (updated at insert and maintenance time).



Follow up to r1762718: CHANGES entry.

event: follow up to r1762718.
We still need to kill kept-alive connections in normal/expiry processing if
the workers are busy or dying.



event: follow up to r1762718 and r1762742: put de condition where it belongs.



event: follow up to r1762718.

On graceful shutdown/restart, kill kept-alive connections before poll()ing
again, avoiding to wait for their "normal" timers (before being woken up)
when they remain the last handled connections.



event: follow up to r1762701.
Keep QUEUE_APPEND()+pollset_add() or QUEUE_REMOVE()+pollset_remove() atomic.

Otherwise when a worker adds an entry in some queue (e.g. KA, lingering), it
might race with the listener in the time between the mutex is released and the
pollset is updated; meanwhile the listener might process the queue and find an
entry no yet in its pollset.

For the lingering queue, the entry could then have been used after its pool
destroyed.

      Since r1753257, "HEAD" method is registered into the registry hash with the M_GET ID.
(r1757672 in 2.4.x)

We iterate over all the values of the registery, so there is no need anymore to have a special case for "HEAD" in  'make_allow()'. It has its own entry now.

With the current code, we have "HEAD" 3 times in the Allow Header field.
This is because we find M_GET 2 times in the registry hash. The first one gives "GET" and "HEAD" (as the special handling), and the second "HEAD" and "HEAD" (as the special handling).


BTW, use APR_ARRAY_PUSH instead of hand coding it, in oder to have the code more readable.
