Special shoutout to Android for not having RTL compatible
variants of nextFocusRight and nextFocusLeft.
Ideally we would have some way to block the user from using
the d-pad to switch between the two panes when in portrait mode,
or make the list pane act as if it's to the left of the details
pane rather than the right when the details pane is open, but I
don't know of a good way to do this. SlidingPaneLayout doesn't
really seem to have been implemented with d-pad navigation in mind.
Thankfully, landscape is the most important use case for gamepads.
The way I'm implementing events using LiveData feels rather
unorthodox, but I'm not aware of anything in the Android framework
that would let me do it in a better way... One option I did
consider was wrapping the cheat lists in LiveData and observing
those, but then CheatsAdapter wouldn't know which cheat had
changed, only that there was some kind of change to the list,
necessitating the use of the not recommended notifyDataSetChanged.
This path isn't really any faster in the normal case,
but it does let us skip waiting for the lock to be available,
which makes a huge difference if the lock is already taken.
It seems like we spend a lot of the game list scanning time in
updateAdditionalMetadata, which I suppose makes sense considering
how many different files that function attempts to open.
With the addition of just one little atomic operation, we can make
it safe to call updateAdditionalMetadata without holding a lock.
FindAllGamePaths may take a little while, and holding the
gameFileCache lock isn't actually necessary until it's time to
put the results returned by FindAllGamePaths into gameFileCache.
The downside of this change is that we have to do an extra
round of JNI in between FindAllGamePaths and Update,
but I don't think that's much of a problem.

This partially reverts commit cbc4989095
due to a crash: https://bugs.dolphin-emu.org/issues/12561
I can't debug what the cause of the crash is due to not having an
Android TV device. Let's just revert this for now to fix the crash.
The same kind of change as the changes made in the previous
commit, but this change is more involved, in particular because
of how SyncProgramsJobService was using display names as keys.
Now that DOL and ELF files are assigned game IDs, all games have
game IDs. (Unless you intentionally craft an ISO file that has
the first bytes set to null, but if you do that I think you can
live with Dolphin creating a file in GameSettings called ".ini")
Back when I wrote this code, I believe I set it to use a custom path
so that the cache would end up in a directory which Android considers
to be a cache directory. But nowadays the directory which Dolphin's
C++ code considers to be the cache directory is such a directory,
so there's no longer any reason to override the default path.
progressMessage can have the invalid value of 0. That
progressMessage was being used for the thread name was
a typo anyway – it's supposed to use progressTitle.
This reduces the build time for incremental builds from about
2 minutes to about 20 seconds. Most people never run the
unit tests on Android anyway (I'm not aware of anyone other
than me ever having done it).
