In Windows and X11, the changes were applied at the time of the preedit
callback. This has been removed and make them applied immediately.
In macOS, the position callback is provided, so do nothing and leave
this to it.
In over-the-spot mode, almost all APIs are disabled.
Applications only need to specify the candidate window position by
`glfwSetPreeditCursorPos`.
We can change style to on-the-spot by setting "on-the-spot" to the
environmental variable `IM_STYLE`.
However on-the-spot mode of X11 has the following problems:
* Status APIs don't work because status callbacks don't work
(at least in my ibus environment)
* Can't specify the candidate window position
This fix is based on shibukawa's fix:
https://github.com/glfw/glfw/pull/658
The differences is the following.
* Remove `X_HAVE_UTF8_STRING` branching since the current logic doesn't use it
* Replace `XNDestroyCallback` for `XNPreeditAttributes` in `XCreateIC`
This fix is based on shibukawa's fix:
https://github.com/glfw/glfw/pull/658d36a164423
Some minor coding style changes are made, but not yet follow glfw's one,
and some comments doesn't follow recent changes. So further work is
needed.
This is a follow-up to 535c3ce632.
That commit made glfw3native.h undefine GLAPIENTRY whenever
GLFW_EXPOSE_NATIVE_GLX or GLFW_EXPOSE_NATIVE_OSMESA was defined, on the
assumption that it was glfw3.h that had defined GLAPIENTRY.
If gl.h or an extension loader header has been included before glfw3.h,
then it has defined inclusion guards preventing GLAPIENTRY from being
defined later when the GLX or OSMesa header includes gl.h.
This commit ensures GLAPIENTRY is only undefined if glfw3.h defined it.

This avoids glfwCreateWindow emitting GLFW_FEATURE_UNAVAILABLE or
GLFW_FEATURE_UNIMPLEMENTED on Wayland because shared code was calling
unimplemented or unavailable platform functions during final setup.
It also makes it consistent with the final setup of full screen windows.
There will not currently be more than one set of threading or timer APIs
selected regardless of how many window systems are enabled, so there is
no need for this extra complexity.
Versions of wayland-scanner prior to 1.17.91 named every global array of
wl_interface pointers 'types', making it impossible to combine several
unmodified private-code files into a single compilation unit.
This overrides that name with a macro for each file, allowing them to
coexist.
