Update for SDL3 coding style (#6717)
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:
#6592
#6593
#6594

SDL_isxdigit() should only accept A-Fa-f, not A-Za-z (it shouldn't use

SDL_ispunct() shouldn't accept spaces (it should use SDL_isgraph()
instead).

Add all missing "is characteristic" stdlib functions
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()

Fixed bug 3468 - _allshr in SDL_stdlib.c is not working properly
Mark Pizzolato
On Windows with Visual Studio, when building SDL as a static library using the x86 (32bit) mode, several intrinsic operations are implemented in code in SDL_stdlib.c.
One of these, _allshr() is not properly implemented and fails for some input. As a result, some operations on 64bit data elements (long long) don't always work.
I classified this bug as a blocker since things absolutely don't work when the affected code is invoked. The affected code is only invoked when SDL is compiled in x86 mode on Visual Studio when building a SDL as a static library. This build environment isn't common, and hence the bug hasn't been noticed previously.
I reopened #2537 and mentioned this problem and provided a fix. That fix is provided again here along with test code which could be added to some of the SDL test code. This test code verifies that the x86 intrinsic routines produce the same results as the native x64 instructions which these routines emulate under the Microsoft compiler. The point of the tests is to make sure that Visual Studio x86 code produces the same results as Visual Studio x64 code. Some of the arguments (or boundary conditions) may produce different results on other compiler environments, so the tests really shouldn't be run on all compilers. The test driver only actually exercised code when the compiler defines _MSC_VER, so the driver can generically be invoked without issue.

Martin Gerhardy
According to https://msdn.microsoft.com/de-de/library/2kzt1wy3%28v=vs.120%29.aspx when one is using /MT for msvc compilations the libcmt.lib is already linked to the binary. This lib includes the symbol that is now guarded (see attached patch) by the #ifndef _MT.

Fixed crash if initialization of EGL failed but was tried again later.
The internal function SDL_EGL_LoadLibrary() did not delete and remove a mostly
uninitialized data structure if loading the library first failed. A later try to
use EGL then skipped initialization and assumed it was previously successful
because the data structure now already existed. This led to at least one crash
in the internal function SDL_EGL_ChooseConfig() because a NULL pointer was
dereferenced to make a call to eglBindAPI().

VS2005 tweaks (thanks, Ozkan!).
Fixes Bugzilla #2895.
His notes:
The following trivial changes make SDL2 tree (mostly) compatible with Visual
Studio 2005:
* SDL_stdlib.c: Similar to VS2010 and newer, VS2005 also generates memcpy(),
(it also generates memset(), see below), so propagate the #if condition to
cover VS2005.
* SDL_pixels.c (SDL_CalculateGammaRamp): VS2005 generates a memset() call for
gamma==0 case, so replace the if loop with SDL_memset().
* SDL_windowsvideo.h: Include msctf.h only with VS2008 and newer, otherwise
include SDL_msctf.h
* SDL_windowskeyboard.c: Adjust the #ifdefs so that SDL_msctf.h inclusion is
always recognized correctly.

the last parameter of XChangeProperty is the number of elements.. and when the element format is 32.. the element is "long" so we have 5 long elements here.
Yes this seems confusing as on mac+linux Long is either 32 or 64bits depending on the architecture, but this is how the X11 protocol is defined. Thus 5 is the correct value for the nelts here. Not 5 or 10 depending on the architecture.

Fixed bug 2802 - [patch] Fix android build compiling in wrong filesystem implementation
Jonas Kulla
The configure script didn't differentiate between Linux and Android, unconditionally compiling in the unix implementation of SDL_sysfilesystem.c.
I'm probably one of the very few people building SDL for android using classic configure + standalone toolchain, so this has gone undetected all along.

Clang static analysis builds should use C runtime directly.
This is a little macro magic to use malloc() directly instead of SDL_malloc(),
etc, so static analysis tests that know about the C runtime can function
properly, and understand that we are dealing with heap allocations, etc.
This changed our static analysis report from 5 outstanding bugs to 30.
5x as many bugs were hidden by SDL_malloc() not being recognized as malloc()
by the static analyzer!

[X11] Reconcile logical keyboard state with physical state on FocusIn
since the window system doesn't do it for us like other platforms.
This prevents sticky keys and missed keys when going in and out
of focus, for example Alt would appear to stick if switching away
from an SDL app with Alt-Tab and had to be pressed again.

Fixed bug 2274 - SDL_ceil is incorrectly implemented when HAVE_LIBC is not defined
Ghassan Al-Mashareqa
The SDL_ceil function is implemented incorrectly when HAVE_CEIL is not defined (HAVE_LIBC not defined).
The following code:
double val = SDL_ceil(2.3);
printf("%g", val);
prints "2.0", as STD_ceil is defined as:
double
SDL_ceil(double x)
{
#ifdef HAVE_CEIL
return ceil(x);
#else
return (double)(int)((x)+0.5);
#endif /* HAVE_CEIL */
}
This functions is used in the SDL_BuildAudioResampleCVT function of the audio subsystem (SDL_audiocvt.c), and causes a bug in that function.

Fixes #2022, do not resume on Android when surfaceChanged
If the app is in landscape mode and the user presses the power button, a pause
is followed immediately by a surfaceChanged event because the lock screen
is shown in portrait mode. This triggers a "false" resume.
So, we just pause and resume following the onWindowFocusChanged events.
Also, wait for SDL_APP_WILLENTERBACKGROUND and SDL_APP_DIDENTERBACKGROUND before
blocking the event pump.
