These used to serve a purpose but now they only cause a dependency loop
between LL*/HL* operations and FilesystemService itself, making it
difficult to strategize filesystem behavior.
When getting a stream for an SVG icon from AppIconService with a
previously-fetched stored icon provided, a double-encoding bug was
preventing a valid image from being obtained.
Adds an event for app invalidation.
Moves iconify_apps to AppIconService and adds RecommenededAppsService,
which holds some logic that used to be in get-launch-apps. The event for
app invalidation is then used by RecommenededAppsService to determine
when to clear the recommended apps cache.
Moves AppIconService, OldAppNameService, and ProtectedAppService to the
new apps module to keep things organized, and updates imports. There
were no interesting init errors. Services creating a database at init
were tested for failures but this wasn't an issue. It turns out
initializing with a database accessor before the db service inits is
okay, but using that database accessor at init is not.
There are now several services related to apps, and
RecommendedAppsService is about to be added, making this a good time to
create a separate module for these services and migrate the legacy
service AppInformationService.
During migration it was realized that most of the initialization needed
to occur at boot.consolidation rather than boot.init because the
database needs to be initialized first.
