36512eca29 mod_c2s,mod_s2s: Fix error on shutdown (Thanks Martin) 
Since there are two calls to done() that can happen, if the timing is
right (or wrong) both can happen, which previously triggered an error.

1d20ec63e6 mod_c2s,mod_s2s: Wrap callback to improve tracebacks 
Should make traces point here instead of timer dispatch, making
debugging easier

a8f4892fe3 mod_c2s,mod_s2s: Wait for sessions to close before proceeding with shutdown steps 
Ensures unavailable presence and other outgoing stanzas are sent.

Waiting for c2s sessions to close first before proceeding to disable and
close s2s ensures that unavailable presence can go out, even if it
requires dialback to complete first.

13dc49d1a7 mod_c2s: Close ports in a separate, earlier event from closing sessions 
Lets other things step in and do things while c2s ports are closed, e.g.
mod_smacks, or other modules with port handlers that forward to c2s.

f56aaf1ba1 mod_c2s,mod_s2s: Disable and close port listeners before closing sessions

6c98ee025e mod_c2s: Fire pre-closing event regardless of connected state 
With mod_smacks, a session can outlive the connection, so whether the
event is fired should not hinge on whether the session is connected or
not.

Helps mod_smacks remove some state.

d02e79c6a9 mod_c2s: Add event just before closing as session 
To allow modules to do things just before the session is closed. The
'(pre-)resource-unbind' events are fired after the stream is closed,
leaving no way to send something.

ef6cb64b9e mod_c2s,etc: Identify stanza object with appropriate function 
Better than duck typing, in case anyone ever passes a non-stanza table
with a 'name' field.

f24aba7b19 mod_c2s: Rename Direct TLS listener 'c2s_direct_tls' for clarity

48216c1dc8 mod_c2s,mod_s2s: Fire event just before writes

requests at optimal times without using timers or nextTick.

814a3a3482 mod_c2s: Guard against LuaSec not returning TLS info (thanks Martin) 
The :info() method has been observed to return nothing ... sometimes.
Unclear what causes it. Perhaps the TLS connection was shut down or
hasn't fully settled?

The LuaSec code has code paths that return nothing or nil, error, so it
is best to guard against it.

db64810141 mod_c2s: Add a Direct TLS listener 
This only differs from 'legacy_ssl' in name, at least on the server
side. For clients this is the one that uses SRV records.

21fa25b27b mod_c2s: Fix traceback if session was destroyed while opening stream (thanks Ge0rG) 
Could happen with the 'opportunistic_writes' setting, since then the
stream opening is written directly to the socket, which can in turn
trigger session destruction if the socket somehow got closed just after
the other sent their stream header.

Error happens later when it tries to `hosts[session.host == nil].events`

846862e1e7 mod_c2s: Improve code style 
We don't use the quoted table indexing style that often, it's not needed

4c4e764e23 mod_c2s, mod_s2s, mod_component, mod_bosh, mod_websockets: Set default stanza size limits 
c2s/bosh/ws streams will default to 256KB, s2s and components to 512KB.

These values are aligned with ejabberd's default settings, which should reduce
issues related to inconsistent size limits between servers on the XMPP network.

The previous default (10MB) is excessive for any production server, and allows
significant memory usage by even unauthenticated sessions.

0fdb85997a mod_net_multiplex: Add support for using ALPN
