There's a potential race condition in the search code: if we have an
outstanding search call to a provider for search "A", and if before it comes
back we do a subsearch for "AB", we won't have any results to pass along.
Previously, we used an empty list when storing the provider results, so we
effectively told the remote search app to filter through this empty list for
any search results that meet the new query, meaning we showed the user 0
results for the provider in this case.
Now that we don't store an empty list, but instead store `undefined`, this race
raises a warning. Solve it by doing an initial search query in this case
instead.
The search code isn't too smart about chained subsearches: now, if we hit this
race while already on a subsearch, we'll do an initial search for the subsearch
query instead, but that is much better than showing the user nothing. This
could be fixed in the future for a performance improvement.

When a notification becomes expanded, it's either already shown,
or in the process of being shown. Don't set the state to SHOWING
again, which confuses our state machine.
The asynchronous nature of extension loading, session loading, and more,
makes the code racy as to what is initialized first, and hard to debug.
Additionally, since gjs is single-threaded, the only code we're running
in a thread anyway is readdir, which is going to be I/O bound, so the
code here is actually likely to be faster.
Drop this in favor of some good old fashioned synchronous loading.
We currently only ensure that width and height are positive, so it
is still possible to pass in values that don't make any sense at all
(which may even result in a crash when exceeding limits imposed by
X11).
There is nothing to screenshot outside the actual screen area, so
restrict the parameters to that.

Rather than create all ShellApps up-front, create them lazily. We really
had no reason to do this before as we were scanning GMenu to get all the
apps, but doing this can remove a need for get_all, which is slow and
memory-hungry.
We want to transition to a system in the future where we have a desktop
file cache. As we no longer differentiate categories or similar, it no
longer makes sense to have app visibility based on categories. Thus,
we no longer need to use gnome-menus to list all apps. The potential
issue here is reloading all desktop files when new files are created,
but this can be dealt with individually.
The "All Applications" view still uses gnome-menus.

Since appDisplay.js makes its own GMenu tree, it's not necessary
anymore. This does mean that searches will show apps in NoDisplay
categories, but that's an obscure enough edge case not to matter.

This does remove support for legacy prefixed app infos with
subdirs, but since we want to remove support for the menu spec,
let's not even bother.

It's a broken method when it comes to giving us a useful GDesktopAppInfo,
and it's hard to fix libgmenu properly, so simply recreate the app info
using the desktop file ID that libgmenu has.
We want to move away from gnome-menus eventually, so the simple
utility method isn't really worth keeping around. Reimplement it
in the one place that uses it.

Long ago, the search system worked in a synchronous manner: providers
were given a query, and results were collected in a single array of
[provider, results] pairs, and then the search display was updated
from that.
We introduced an asynchronous search system when we wanted to potentially
add a Zeitgeist search provider to the Shell in 3.2. For a while, search
providers were either async or sync, which worked by storing a dummy array
in the results, and adding a method for search providers to add results
later.
Later, we removed the search system entirely and ported the remaining
search providers to simply use the API to modify the empty array, but the
remains of the synchronous search system with its silly array still
lingered.
Finally, it's time to modernize. Promises^WCallbacks are the future.
Port the one remaining in-shell search engine (app search) to the new
callback based system, and simplify the remote search system in the
process.
`a + b ? c : d` is parsed as `(a + b) ? c : d`, not the more intuitive
`a + (b ? c : d)`.
This was causing a bad slide animation and Clutter warnings when coming
out of the overview.
The org.gnome.login-screen schema contains a key to disable the
power/restart buttons; our support for this fell victim to the
new combined status menu, add it back.
