Also works around a bug where CMake's ninja generator doesn't properly handle ||'s on POST_BUILD commands, making the || apply to the whole build like `<link> && custom0 || custom1`
Will manually controlling both an accelerometer and a gyroscope at the
same time be reasonable to do? No idea. Was this easy to implement
thanks to the input override system? Yes.
Fixes https://bugs.dolphin-emu.org/issues/12443.
In UpdateInput, lock m_devices_population_mutex before m_devices_mutex
to be consistent with other ControllerInterface functions. Normally the
former lock isn't needed in UpdateInput, but when a Wii Remote
disconnects it calls RemoveDevice which results in the mutexes being
locked in the wrong order.
This gets rid of a blocking operation, improving performance and fixing
https://bugs.dolphin-emu.org/issues/12893.
This also makes us no longer directly access the state of certain UI
elements from the CPU thread, which probably wasn't thread-safe but
doesn't seem to have caused any observable issues so far.
Up until now, there have been two settings on Android that stored the
selected Wii Remote extension: the normal one that's also used on PC,
and a SharedPreferences one that's used by the overlay controls to
determine what controls to show. It is possible for these two to end up
out of sync, and my input changes have made that more likely to happen.
To fix this, let's rework how the overlay controller setting works.
We don't want it to encode the currently selected Wii Remote extension.
However, we can't simply get rid of the setting, because for some Wii
games we need the ability to switch between a GameCube controller and a
Wii Remote. What this commit does is give the user the option to select
any of the 4 GameCube controllers and any of the 4 Wii Remotes. (Before,
controllers 2-4 weren't available in the overlay.) Could be useful for
things like the Psycho Mantis fight in Metal Gear Solid. I'm also
switching from SharedPreferences to Dolphin.ini while I'm at it.
It's missing a lot of features from the PC version for now, like
buttons for inserting functions and the ability to see what the
expression evaluates to. I mostly just wanted to get something in
place so you can set up rumble.

This is a small regression from KillRenderer, which caused duplicated
frames to be counted on the FPS counter when the "Skip Presenting
Duplicated Frames" option was disabled.
This way, Android (which will show groups in the order they're defined)
will show groups in a more logical order similar to DolphinQt.
The main thing that was annoying me was how early Rumble was for
Wii Remotes. Some of the other changes I'm making in this commit,
like the order of Shake/Tilt/Swing, are more arbitrary and were
made for consistency with DolphinQt. But there are also places
where I didn't go all the way with matching DolphinQt. Most notably,
DolphinQt puts sticks before buttons, but I don't see any reason
to do that for Android.
Unlike PCs, Android doesn't really have any input method (not counting
touch) that can reasonably be expected to exist on most devices.
Because of this, I don't think shipping with a default mapping for the
buttons and sticks of GameCube controllers and Wii Remotes makes sense.
I would however like to ship default mappings for a few things:
1. Mapping the Wii Remote's accelerometer and gyroscope to the device's
accelerometer and gyroscope. This functionality is useful mainly
for people who use the touchscreen, but can also be useful when
using a clip-on controller. The disadvantage of having this mapped
by default is that games disable pointer input if the accelerometer
reports that the Wii Remote is pointed at the ceiling.
2. Mapping GC keyboards for use with a physical keyboard, like on PC.
After all, there's no other way of mapping them that makes sense.
3. Mapping rumble to the device's vibrator.
Aside from the GC keyboards, this approach is effectively the same as
what we were doing before the input overhaul.
This is a battery-saving measure. Whether a sensor should be suspended
is determined in the same way as whether key events and motion events
should be handled by the OS rather than consumed by Dolphin.
When Android presents an input event to an app, it wants the app to
return true or false depending on whether the app handled the event or
not. If the event wasn't handled by the app, it will be passed on to
the system, which may decide to take an action depending on what kind
of input event it is. For instance, if a B button press is passed on to
the system, it will be turned into a Back press. But if an R1 press is
passed on to the system, nothing in particular happens.
It's important that we get this return value right in Dolphin. For
instance, the user generally wouldn't want a B button press to open
the EmulationActivity menu, so B button presses usually shouldn't be
passed on to the system - but volume button presses usually should be
passed on to the system, since it would be hard to adjust the volume
otherwise. What ButtonManager did was to pass on input events that are
for a button which the user has not mapped, which I think makes sense.
But exactly how to implement that is more complicated in the new input
backend than in ButtonManager, because now we have a separation between
the input backend and the code that keeps track of the user's mappings.
What I'm going with in this commit is to treat an input as mapped if
it has been polled recently. In part I chose this because it seemed
like a simple way of implementing it that wouldn't cause too many
layering violations, but it also has two useful side effects:
1. If a controller is not being polled (e.g. GameCube controllers in
Wii games that don't use them), its mappings will not be considered.
2. Once sensor input is implemented in the Android input backend,
we will be able to use this "polled recently" tracking to power down
the sensors at times when the game is using a Wii Remote reporting
mode that doesn't include motion data. (Assuming that the sensor
inputs only are mapped to Wii Remote motion controls, that is.)
Android doesn't let us poll inputs whenever we want. Instead, we
listen to input events (activities will have to forward them to the
input backend), and store the received values in atomic variables
in the Input classes. This is similar in concept to how ButtonManager
worked, but without its homegrown second input mapping system.
ButtonManager is very different from how a normal input backend works,
and is making it hard for us to improve controller support on Android.
The following commits will add a new input backend in its place.
When that setting is enabled, m_xfb_entry is initially not present (during the phase where a shader compilation progress bar would be shown). The main path checks for m_xfb_entry, but the software renderer fallback path didn't.
Fixes another aspect of https://bugs.dolphin-emu.org/issues/13172.
Before, it used a fallback where it returned a default object, where the width and height were set to 0. Presenter::Initialize() used GetSurfaceInfo to set the backbuffer size, then used that size when initializing the on-screen UI (even for the software renderer, where the on-screen UI isn't currently present), which meant that ImGui got a window size of 0 and thus resulted in a failed assertion.
Although BindBackbuffer checks for size changes, it doesn't help because ImGui has already been initialized, and the size hasn't actually changed since initialization occured.
