It's starting at 1 hour because os.time(os.date("!*t") returns the wrong
time depending on system timezone. os.time() already returns the number
of seconds since epoch in UTC so just use that.

In a typical Jitsi Meet setup, this plugin can be used to limit the number of
occupants in a meeting room, while ignoring "utility" users. Such a
configuration could be:

    muc_max_occupants = 2
    muc_access_whitelist = {
        "focus@auth.meet.jitsi";
    }

It would be expected that this configuration allows two users to attend the
meeting room, but in practice only one is allowed, because the whitelist is not
honoured.

This commit fixes it by actually updating the `user` and `domain` variables
being checked. After this change, the scenario above works just fine.

The patch and Prosody 0.11 is required for the XMPP stream resume

https://hg.prosody.im/prosody-modules/raw-file/c49fea05772e/mod_smacks/mod_smacks.lua

The 'previd' query parameter will be use to match user id of the session
being resumed when the smacks module and token authentication are
enabled in Prosody. Otherwise user gets new random id every time and
this doesn't work with the smacks module.

If the dominant speaker leaves their object will be gone from the mapping.

* hook on websocket events

* initial session for bosh and websockets

* fixes async_handler_wrapper

adds missing runner variable from async to async_handler_wrapper
removes redundant have_async definition in wrap_async_run, defined at top of module

* only use async handler wrapper,
remove async_wrap_run

* Adds package that can configure using turnserver for jitsi-meet.

Activates http2 on the nginx host and uses the alpn send with the web requests to multiplex traffic to be served as web of proxied to the turn server.
It needs nginx at least v1.13.10.
Adds turncredentials module from Philipp Hancke, with small modification (all int values for hosts need to be strings/tostring()) in order to be able to use the module with prosody 0.11.

* Moves loading of stream after loading stream module (50-..).

* Leaves DISABLE_TCP_HARVESTER to be handled by jvb.

* Fixes comments.

* Properly detect first time coturn install and configure it.

* Handles upgrading from jetty serving web.

* Does not create jvb user if already exists.

* Fixes let's encrypt and adds turnserver handling.

* Enables use of turn server in config.js if available.

* Adds a check whether prosody config exists.

There are cases where deployments can still have configured prosody in the main prosody config in /etc/prosody.

There are modules that will not work with prosody 0.10 as they depend on util.async. Adds a safeguard and print error about it in the logs.
And others that just do not work because of the muc module API that they use.

* Correctly process speaker stats events when the conference contains a subdomain

* first pass at mod_muc_domain open source plus example

* doc - prosody config and config.js examples for mapper

Adds option to limit number of outgoing calls per user.

use optional prefix in poltergeist room lookup

Doing few changes needed for general config and for tokens.

Adds the component which receives the messages from client and a module which enabled on a virtual host will start advertising the component. When clients discover the component they will send message to the component with the name of the room where the dominant speaker event happen.

The original presence stanza generation code for a poltergeist
has been re-factored and simplified a bit. Every time a
poltergeist presence is updated we first check that the poltergeist
still exists.

* Adds an option to disable features based on token data.

Reverts changes from b84e910086, removes disableDesktopSharing option and an interface_config option.

* Disable recording button based on token features data.

Hide recording if local participant isGuest and roles based on token.
When enableUserRolesBasedOnToken is enabled we were not hiding the record button for guests.

* Adds filtering of jibri iqs and rayo based on features.

Moves feature checking in separate utility function.
Renames utility method.

* Adds a footer text when outbound-call is not feature enabled.

* Fixes comments.

Previously a new call id was generated for INVITE and CANCEL.
Now the id generated during the initial INVITE will be used for
corresponding CANCEL events. Also, adding the ability to
trigger a call cancel via the poltergeist update api.

The current poltergeist http api immediately returns
and does not wait for async work in the handler to finish. This
mostly occurs when a public asap key needs to be fetched due
to a cache miss. The fix implements the strategy described at
https://prosody.im/doc/developers/http.html

This should allow us to have a consistent convention and assist
with client translation of status strings.
