When making a poll, an event is registered on each channel. Once
a notification is sent on a channel, only the events of the
notified channel are removed. A pointer to the event is kept
in all other channel the user subscribes to until those channel
are notified.
Since a user usually has many mail.channels but only a few active ones,
a new event and a bunch of pointers are created at each poll and
never removed.
This fix simply remove the pointers to the current event at the
end of a poll.

`this._id` is overriden by the crosstab_bus, so the event handlers
weren't unbound at destroy.

Before this commit, chat windows could not be sync'ed
between browser tabs for about 10 to 20 seconds.
This issue is caused by the implementation of the
crosstab longpolling, which uses a master-slave
architecture with a single tab being the master tab.
The master tab is responsible for performing the
longpolling RPC, so that it keeps a single HTTP request
for all Odoo tabs. Other tabs are synchronized through
the local storage.
When the master tab was closed, a new master tab election
must occur. However, this process was taking up to 20 seconds,
due to the tab waiting for their next tick on the local
storage to initiate a new election. The tick for a slave
tab is 10 seconds, and it may jumps a tick in case the master
tab is closed exactly before the tick, hence extending the
duration to 20 seconds.
This commit fixes the problem by ensuring that the tab
election for the longpolling is done right after the master
tab is closed. As a result, a new master tab should follow
right away.
Steps to reproduce:
1. open two tabs.
2. open a chat window in one tab: it opens in both tabs.
3. fold/unfold chat window in one tab: both tab should sync.
4. refresh both tabs.
5. fold/unfold chat window in one tab: both tab should not sync.
6. after 10 or 20 seconds, both tabs should again sync.

Running the bus garbage collector synchronously during the handling of a
request can stall the request for a very long time.
Instead, we add this step to the existing auto-vacuum scheduled job that
handles this kind of housecleaning. It brings another interesting bonus:
it can be scheduled outside of peak hours, which will avoid blocking other
bus-related transactions (the GC deletes a lot of rows and takes a lot
of exclusive locks in the database)

Before this commit, there was no livechat menu when accessing it from
the customer URL, e.g. `http://mycompany.odoo.com/im_livechat/support/1`)
This is due to missing JS modules, such as the root widget.
Also, the crosstab polling directly requires the session module,
because the public root widget does not return the session module
from the OdooEvent `get_session`.

Revision on bus refactoring: https://github.com/odoo/odoo/commit/6448420c5dd160470e465dee7729d19d8d5e7bab
Before this commit, when a user was disconnected for a very long
time, he would receive lots of chat notifications on his next login.
Here is an example of weird behaviour with this issue:
- User folds and unfolds a chat window 50 times
- User disconnects for more than 50 seconds
- User reconnects
==> the chat window rapidly folds and unfolds itself 50 times!
This issue comes from the fact that after 50 seconds without any
longpolling, the web client ignores the last tracked notification
and sents the ID `-1` to the server.
The web client always provides a notification ID to the server
on a `longpolling/poll`. Usually, the server returns all
notifications of the user with an ID greater than the provided ID.
There is an exception with ID `0`, in which all notifications since
the last connection of the user are returned.
The cause of the issue is a mismatch of the special notification
ID between the server and the web client. For the web client, the
ID `-1` is used for not tracking any notification, whereas the
server uses the ID `0` for this case. As a result, when the server
receives the value `-1`, it returns all notifications having an ID
greater than `-1`. In other words, it returns all notifications
related to this user, even the ones received long time ago!
This commit fixes the issue by enforcing the special notification ID
`0` on both the webclient and server.
Note that this logic is similar to 11.0:
- The webclient uses the ID `-1` most of the time to define 'untracked':
https://github.com/odoo/odoo/blob/11.0/addons/bus/static/src/js/bus.js#L154
- However, it passes the ID `0` to the server:
