This fixes problems with controllers not being re-detected when a computer goes to sleep and a controller is removed and plugged back in while it's asleep.
Fixes SDL_CreateWindowAndRenderer (and similar situations) not choosing a Metal backend. See #3991.
Passing an explicit backend into CreateWindow, eg SDL_WINDOW_OPENGL or SDL_WINDOW_METAL, will still prevent the window from being used with other backend types.
SDL_isxdigit() should only accept A-Fa-f, not A-Za-z (it shouldn't use
SDL_isalpha()).
SDL_ispunct() shouldn't accept spaces (it should use SDL_isgraph()
instead).
SDL has been missing a bunch of these 'isX' functions for some time,
where X is some characteristic of a given character.
This commit adds the rest of them to the SDL stdlib, so now we have:
- SDL_isalpha()
- SDL_isalnum()
- SDL_isblank()
- SDL_iscntrl()
- SDL_isxdigit()
- SDL_ispunct()
- SDL_isprint()
- SDL_isgraph()
This uses the mechanism added in emscripten-core/emscripten#10843
which was applied to SDL1 and OpenAL. This adds the same for SDL2.
This also reverts commit 865eaddffed50dbd13e6564c3f73902472cf74e8
which did something similar, but the new mechanism is more effective.
The DJGPP compiler emits many warnings for conflicts between print
format specifiers and argument types. To fix the warnings, I added
`SDL_PRIx32` macros for use with `Sint32` and `Uint32` types. The macros
alias those found in <inttypes.h> or fallback to a reasonable default.
As an alternative, print arguments could be cast to plain old integers.
I opted slightly for the current solution as it felt more technically correct,
despite making the format strings more verbose.

This patch fixes the warnings seen when compiling the Wayland backend. This will also be required in the future to avoid issues with compilation.
When SleepConditionVariableSRW() releases the SRW lock internally, it causes
our SDL_mutex_srw state to become inconsistent. The lock is unowned yet inside,
the owner is still the sleeping thread and more importantly the owner count is
still 1.
The next time someone acquires the lock, they will bump the owner count from 1
to 2. At that point, the lock is hosed. From the internal lock state, it looks
to us like that owner has acquired the lock recursively, even though they have
not. When they call SDL_UnlockMutex(), it will see the owner count > 0 and not
call ReleaseSRWLockExclusive().
Now when someone calls SDL_CondSignal(), SleepConditionVariableSRW() will start
the wakeup process by attempting to re-acquire the SRW lock. This will deadlock
because the lock was never released after the other thread had used it. The
thread waiting on the condition variable will never be able to wake up, even if
the SDL_CondWaitTimeout() function is used and the timeout expires.
There were two different implementations of IsBluetoothXboxOneController(), one
in SDL_hidapi_xbox360.c and one in SDL_hidapi_xboxone.c. The latter had been
updated to include USB_PRODUCT_XBOX_ONE_SERIES_X_BLUETOOTH while the former had
not.
This mismatch led to the Xbox Series X failing on macOS only. We have special
code for handling the 360Controller driver for macOS which requires us to use
the Xbox 360 driver for wired Xbox One controllers, and the SDL_hidapi_xbox360
version of IsBluetoothXboxOneController() was used to determine which devices
were wired.
In addition to adding the missing USB_PRODUCT_XBOX_ONE_SERIES_X_BLUETOOTH, this
change moves IsBluetoothXboxOneController() into a single shared function which
will ensure this bug won't happen again.
This is caused by the Metal renderer recreating the window because by default we create an OpenGL window on macOS.
It turns out that at least on macOS 10.15, a window that has been initialized for OpenGL can also be used with Metal. So we'll skip recreating the window in that case.
