In a multi device world, it's possible to receive a receipt for a sync
message before the sync message actually arrives. In this case we need
to keep the receipt around and the process it when the message shows up.
My current version of chromium inexplicably exposes a crippled version
of chrome.browserAction even though we are now a packaged app and should
not have that functionality exposed to us anymore. This results in some
errors to the tune of "property 'foo' of undefined".
It also doesn't support the innerBounds property for window creation,
only the older (deprecated) bounds property.
Also make it accessible by providing a mode argument to the install
function. Previously developers could just edit the url but we no longer
have the address bar as an app window, so now they must close the
default installer and run the following from the background page
console: `extension.install('standalone')`.
In the production build, this should result in an error since it is not
supported / the register page is not included there.
Appify tabs, windows, browserAction
Port the extension.windows.focus function to new window api and
generalize its error handling in the case where the requested window
does not exist. An error will be passed to the callback.
Port extension.browserAction and rename it to the more generic
extension.onLaunched.
Use of the id option when opening a window ensures that attempting to
open a duplicate window merely focuses the existing window.
Finally, after registration, close the options window and open the
inbox.
Port extension.remove
Add window.storage to the background page, which loads all data from the
'items' store in indexeddb, caching them in memory for synchronous
access, then override textsecure storage to use that in memory store.
Storing multiple sessions in a single indexeddb record is prone to
clobbering data due to races between requests to update multiple device
sessions for the same number, since you have to read the current state
of the device->session map and update it. Splitting the records up makes
it so that those updates can be made in parallel. Selecting all the
sessions for a given number can still be done efficiently thanks to
indexeddb range queries.
