This fixes restoring the cursor clip rectangle after the mouse has moved off of the window.
Also try to better synchronize cursor visibility with mouse position changes when changing relative mode. This doesn't work perfectly, but it seems to improve things on Windows.
On Wayland -- or at least on some Wayland implementations -- windows
aren't shown until something has been rendered into them. For the
'checkkeys' test program, this means that keyboard input isn't
registered, making the program rather useless.
By creating a renderer and presenting once, the window is properly
displayed, and the test behaves as it does under X11 (including
XWayland).
The exact same thing was done with testmessge in 1cd97e2695 (PR #4252)
Don't rely on checking __clang_major__ since it is not comparable
between different vendors. Don't use "#pragma clang attribute" since it
is only available in relatively recent versions, there's no obvious way
to check if it's supported, and just using __attribute__ directly (for
gcc as well) results in simpler code anyway.
The __clang_major__ and __clang_minor__ macros provide a marketing
version, which is not necessarily comparable for clang distributions
from different vendors[1]. In practice, the versioning scheme for
Apple's clang is indeed completely different to that of the llvm.org
releases. It is thus preferable to check for features directly rather
than comparing versions.
In this specific case, __builtin_bswap16 was being used with older
Apple clang versions that don't support it.

If we are already in the desired mode, changing it is a no-op at best,
and harmful at worst: on Xwayland, it sometimes happens that we disable
the crtc and cannot re-enable it.

- cmake, configure (CheckDLOPEN): --enable-sdl-dlopen is now history..
detach the dl api discovery from SDL_LOADSO_DLOPEN functionality.
define HAVE_DLOPEN. also define DYNAPI_NEEDS_DLOPEN (CheckDLOPEN is
called only for relevant platforms.)
- update SDL_config.in and SDL_config.cmake accordingly.
- SDL_dynapi.h: set SDL_DYNAMIC_API to 0 if DYNAPI_NEEDS_DLOPEN is
defined, but HAVE_DLOPEN is not.
- pthread/SDL_systhread.c: conditionalize dl api use to HAVE_DLOPEN
- SDL_x11opengl.c, SDL_DirectFB_opengl.c, SDL_naclopengles.c: rely
on HAVE_DLOPEN, not SDL_LOADSO_DLOPEN.
- SDL_config_android.h, SDL_config_iphoneos.h, SDL_config_macosx.h,
SDL_config_pandora.h, and SDL_config_wiz.h: define HAVE_DLOPEN.
Closes: https://github.com/libsdl-org/SDL/pull/4351
According to https://cmake.org/cmake/help/v3.0/module/GNUInstallDirs.html
`${CMAKE_INSTALL_LIBDIR} ` is only variable which should be used as base
directory. Without that patch on 64 bit archs libraries, cmake modules and
pkgconfig file are installed for example in /usr/lib6464 base directory.
This patch fixes#4621.

Without this change, driver names don't get matched correctly;
for example "a" can get matched with "alsa" since it only checks
whether the string matches up to the length of the requested
driver name.

b08b1bde introduced a subtle bug. Despite not using D-Bus types directly,
the code used the SDL_USE_LIBDBUS definition set by SDL_dbus.h to conditionally
compile calls SDL_DBus_ScreensaverTickle() and SDL_DBus_ScreensaverInhibit().
As a result, it still compiled without SDL_dbus.h included, but screensaver
suspension silently failed to work.
The D-Bus stuff could probably use some tweaks to be harder to accidentally
break, but for now just restore the header includes.
SDL_Vulkan_GetDrawableSize() doesn't always return a size which is
within the Vulkan swapchain's allowed image extent range.
(This happens on X11 a lot when resizing, which is bug #3287)
Clamp the value we get back from SDL_Vulkan_GetDrawableSize() to this
range. Given the range usually is just a single value, this is almost
always equivalent to just using the min or max image extent, but this
seems logically most correct.
