This fixes UBSAN errors reported by running our testsuite, importing the
TPS demo, and running the TPS demo. I have tried, wherever possible, to
fix issues related to reported issues but not directly reported by UBSAN
because thse code paths just happened to not have been exercised in
these cases.
These fixes apply only to errors reported, and caused by, core/
The following things have been changed:
* Make sure there are no implicit sign changing casts in core.
* Explicitly type enums that are part of a public API such that users of
the API cannot pass in wrongly-sized values leading to potential stack
corruption.
* Ensure that memcpy is never called with invalid or null pointers as
this is undefined behavior, and when the engine is built with
optimizations turned on leads to memory corruption and hard to debug
crashes.
* Replace enum values only used as static values with constexpr static
const values instead. This has no runtime overhead. This makes it so
that the size of the enums is explicit.
* Make sure that nan and inf is handled consistently in String.
* Implement a _to_int template to ensure that all of the paths use the
same algorhithm, and correct the negative integer case.
* Changed the way the json serializer precision work, and added tests to
verify the new behavior. The behavior doesn't quite match master in
particulary for negative doubles as the original code tried to cast -inf
to an int. This then led to negative doubles losing all but one of
their decimal points when serializing. Behavior in GDScript remains
unchanged.

Revert "Fix InputEvent crash when opening project"
This reverts commit abb9c0f171.
Introduce a compatibility function for projects affected by the
device id clash reversal
Since the reverted PR introduced changes in the project.godot
file, it seems prudent to introduce a compatibility function for
such affected projects.
`InputMap::ALL_DEVICES` and `InputEvent::DEVICE_ID_EMULATION` have the
same value `-1`.
Change value of `InputMap::All_DEVICES` so that it's different from
`InputEvent::DEVICE_ID_EMULATION`. `InputEvent::DEVICE_ID_EMULATION`
is part of the API and can't be changed without potentially breaking
projects.
Gather all special device constants in a single location inside
`InputEvent`.
Add a converter to project settings, that takes care of adjusting
project files during loading.
- Returns an empty list when there's not registered plugins, thus preventing the creation of spurious iterator objects
- Inline `Godot#getRotatedValues(...)` given it only had a single caller. This allows to remove the allocation of a float array on each call and replace it with float variables
- Disable sensor events by default. Sensor events can fired at 10-100s Hz taking cpu and memory resources. Now the use of sensor data is behind a project setting allowing projects that have use of it to enable it, while other projects don't pay the cost for a feature they don't use
- Create a pool of specialized input `Runnable` objects to prevent spurious, unbounded `Runnable` allocations
- Disable showing the boot logo for Android XR projects
- Delete locale references of jni strings
Fixes#81758
DisplayServerWeb::process_joypads handles buttons 6 and 7 of the
HTML5 Standard Gamepad as a special case by doing:
`input->joy_axis(idx, (JoyAxis)b, s_btns[b]);`
This doesn't work because there is no JoyAxis 6 or 7 in the enum
To fix this we use JoyAxis::TRIGGER_LEFT and TRIGGER_RIGHT for button 6
and 7
However since we are now lying to input->joy_axis we also need to lie in
the mappings for the standard gamepad in godotcontrollersdb.txt,
otherwise input->joy_axis will try to find a mapping to axis 4(LT) and
axis 5(RT) that's not defined.
Therefore we set lefttrigger to +a4 and righttrigger to +a5 in the
mapping, to match what we are actually sending.
A cleaner, and more involved fix to this would be modifying
input->joy_button so that it can handle analog buttons and map them to
axes preserving their value instead of converting to boolean
