Added the following Javascript hooks:
* ext.echo.notifications.beforeRender: Firing before a group of
notification widgets are rendered, whether in the popup, in
the special page, or in a cross-wiki bundle (which requires
async loading)
* ext.echo.badge.countChange: Fired when the badge count changes
with the notification type, count and the label count for
display purposes.
* ext.echo.popup.onInitialize: Fired when the popup is opened and
after notifications were fetched, with the context of the popup
notification type.
* ext.echo.special.onInitialize: Fired when the special page is
ready and notifications were fetched. Note that it will be fired
whenever the special page is updated with notifications list,
as well, like when changing filter, remote wiki or pagination.
The hooks were also documented in hooks.txt
Bug: T146296

The fade in/out animation is asynchronous. This means that if we are
sorting multiple items one after the other, by the time the item faded
out, it will be reinserted back into the wrong position, breaking the
sorting.
This also broke the promise of OO.SortedEmitterList whereby all its items
are always in order.
The way to fix this was to force a better synchronization with the item
order while we hide and show the item in its new place. To do that,
a new widget is created as a fake clone of the old one, in the original
position of the old one. The original item is then reinserted (while hidden)
to the proper location -- preserving order. The fake clone is then faded
out, and the real item is then faded in.
For this to work properly, the cloned item had to preserve some of the
original item's information, like timestamp, foreigness and id. However,
since both the real item and the fake new clone have the same details,
the clone fakes its ID by adding a fraction to it - promising that the
fallback in case of equal timestamps (which happens on the real and
cloned items) will still resolve with some decision about the placement
of the items rather than (falsely but understandably) decide they are
both the same.
Since this whole animation is somewhat of a hack, the list now has a
configuration parameter to turn the animation on.
The animation is on in the popups, but off in the special page.

* Add ISO 8601 date format to notification output
This is actually supposed to be the only output date format used,
per https://www.mediawiki.org/wiki/API:Data_formats#Timestamps , but
I'm not doing anything to deprecate the others right now.
* Change wgEchoSeenTime to use ISO 8601. mwgrep and extension grep do
not show any usages. However, since it is a breaking change, to
minimize disruption, I'm also using this opportunity to change
'message' to 'notice'.
* Remove wgEchoInitialNotifCount. I was going to also change 'message'
to 'notice' here too, but then I saw it was totally unused.
(It was read in Echo to populate a JS variable, but then it was
unused.)
* Make sure the Special:Notifications page aggregation by days is
done by local days, even though the timestamp per item is still
UTC. This is to make sure the days are displayed correctly in
the local timezone.
* Change all reverse sorting callbacks to handle comparisons of
ISO 8601.

When there are only foreign notifications, marking them all
as read empties the flyout completely. With this change,
we now show the placeholder widget with the 'no notifications'
message instead.

When we are viewing a certain read state filter ('read' or 'unread')
the visibility of items should correspond to that state even when
the user marks a specific item as read/unread. That means that the
system should remove these items from view when the action is taken.
In this commit:
* The controller makes the judgment of whether to remove items when
read/unread action is taken, based on whether a filter is set.
* We clean up the terminology of discard - no more 'remove' - to
make sure we have consistency in the code.
* Related: The 'discard' event is now scoped within the hierarchy;
meaning, lists emit 'discard' when an item is removed, grouplist
emits 'discard' when a group is removed, and the manager emits
'discard' when an entire notification model is removed. This
means we can actually have proper hierarchy and organization with
a single event, and not worry about clashing between the intentional
'discard' action and the event 'remove' that is also used while
resorting happens.
* The model manager emits a discard event when a model is removed
so that the general list can listen to the manager and remove an
entire batch of items if needed.
* The pagination model now updates the count for the current page
rather than some vague notion of the last page. This is also
updated when the controller removes items, so we can get an
accurate count in the page for the number of notifications that
are displayed.

Show an API failure message if the request failed.
Also take this opportunity to show a message in case
there are no notifications at all.

We don't show an error message in this case, just an
empty popup, so that should be fixed regardless.
