Queue messages and handle them sequentially, each time waiting for promises to
resolve before handling the next message.
Updates #1899, which likely happens because an error message is received
before messages have been fetched.
Goal is to fix a timing bug that results in `show` being triggered
before the `ChatBoxView` has been initialized, which means that 1:1
chats aren't opened when you reload the page.
- Rename `chatRoomOpened` event to `chatRoomViewInitialized`
- Rename `chatBoxInitialized` to `chatBoxViewInitialized` and trigger only for `ChatBoxView` instances.
- New event `headlinesBoxViewInitialized`
- Trigger the `chatBoxInitialized` event when a new `_converse.ChatBox` is opened.
- Add support for switching ephemerality after message creation
- Move more methods from ChatBox and ChatRoom to utils/stanza.js
- Rename 'ephemeral' to 'is_ephemeral' since it's a boolean
- Move headless one-on-one chat functionality into converse-chat
- Split converse-headline into converse-headlines and converse-headlines-views
- Add api in `_converse.api.chatboxes` for creating chatboxes
- Add `_converse.api.controlbox.get` method
Depend on latest backbone.browserStorage which has support for IndexedDB
via localforage.
Storage operations are now asynchronous and transactional.
Bugs fixed (mostly by waiting for operations to complete):
* Rooms are now fetched asynchronously, so wait before triggering `show`
or when closing.
* Make sure chat create/update transactions complete before firing events
* Make sure chats and messages have been fetched before creating new ones.
* When doing a `fetch` with `wait: false` on a collection and then
creating a model in that collection, then once the read
operation finishes (after creating the model), the collection is emptied again.
* Patch and wait when saving.
Otherwise we have previously set attributes overriding later ones.
* Make sure api.roomviews.close returns a promise
Test fixes:
* Chats are now asynchronously returned, so we need to use `await`
* Wait for the storage transaction to complete when creating and updating messages
* Wait for all chatboxes to close
Otherwise we get sessionStorage inconsistencies due to the async nature of localforage.
* Wait for room views to close in spec/chatroom.js
In the process, remove the `closeAllChatBoxes` override in
converse-controlbox by letting the `close` method decide whether it
should be closed or not.
Unfortunately this doesn't work on Firefox and there's no proper
workaround. https://github.com/philipwalton/flexbugs/issues/108

Revert "Bugfix. Properly insert error messages and spinner"
This reverts commit 6a419cc145.
Revert "Use flexbox to keep the chat scrolled down"
This reverts commit dd91d3cc55.
By using `display: flex` and `flex-direction: column-reverse`, the chat
now automatically scrolls down when loaded, without requiring any
extra JavaScript.
We still need to scroll down with JavaScript when sending a message.
By using `column-reverse`, the messages container now works in reverse.
So the newest message is the first element in the container and the
oldest message is the last. This is the reverse of before.
Due to this, this change will likely break some plugins.
