We can't actually tell yet whether a controller has paddles, so this code isn't effective, but I'll file an upstream issue and see if we can get that resolved.

This heuristic for gamepads without a more specific mapping already
tried two incompatible conventions for handling triggers: the Linux
Gamepad Specification uses hat switch 2 for the triggers (for whatever
reason), but the de facto standard set by the drivers for older Xbox
and Playstation controllers represents each trigger as the Z-axis of
the nearest analog stick.
Android documentation encourages Bluetooth gamepad manufacturers to use
a third incompatible convention where the left and right triggers are
represented as the brake and gas pedals of a driving simulator
controller. The Android convention also changes the representation of
the right stick: instead of using X and Y rotation as a second pair
of axes, Android uses Z position as a second horizontal axis, and
Z rotation as a second vertical axis.
Try to cope gracefully with all of these. This will hopefully resolve
the issue described in #5406 (when using unpatched kernels).

The bitfield `mapped` has two different sets of meanings, depending
whether we're setting up the triggers or the d-pad. Represent them
as symbolic constants rather than opaque integers.

The annotations have been added to SDL_mutex.h and have been made public so applications can enable this for their own code.
Clang assumes that locking and unlocking can't fail, but SDL has the concept of a NULL mutex, so the mutex functions have been changed not to report errors if a mutex hasn't been initialized. We do have mutexes that might be accessed when they are NULL, notably in the event system, so this is an important change.
This commit cleans up a bunch of rare race conditions in the joystick and game controller code so now everything should be completely protected by the joystick lock.
To test this, change the compiler to "clang -Wthread-safety -Werror=thread-safety -DSDL_THREAD_SAFETY_ANALYSIS"
I updated .clang-format and ran clang-format 14 over the src and test directories to standardize the code base.
In general I let clang-format have it's way, and added markup to prevent formatting of code that would break or be completely unreadable if formatted.
The script I ran for the src directory is added as build-scripts/clang-format-src.sh
This fixes:

This works around udev event nodes arriving before hidraw nodes and the controller being opened twice - once using the Linux driver and once by the HIDAPI driver.
This also fixes a kernel panic on Steam Link hardware due to trying to open the hidraw device node too early.
A delay of 10 ms seems to be a good value, tested on Steam Link hardware.
Refactor the previous sandbox check in a standalone function that also
includes Snap support.

This will make it possible to have mappings for different controllers
that have the same VID/PID. This happens frequently with some generic
controller boards that have been reused in many products.

This prevents an assertion whem LINUX_JoystickGetGamepadMapping tried to
open the stick temporarily and messed with global state by doing so. Now
the global state is only set in LINUX_JoystickOpen, but the common code
is shared by both interfaces.
Fixes#4198.
At least on bluetooth the guid user the version reported by the
bluetooth device. Which for Atari vcs controllers is the firmware
version. However the mapping will stay the same regardless of firmware
version, so ignore the version entirely to avoid needing a new mapping
entry for each firmware version.
