Merge 7c224bcd71 into 8e15281d34

This adds the glfwGetGLXFBConfig function for querying the GLXFBConfig
the GLXWindow of a window.

This commit is a squashed and modified version of PR #1925 by knokko.
The following changes were made by elmindreda:

The function signature was changed to handle GLXFBConfig being an opaque
value in core GLX.  The function error checks were fixed and updated.
The struct member name was changed.  The struct member clearing on
context destruction was removed.  All documentation snippets were
updated.

Closes #1925

-## Compiling GLFW

-GLFW is written primarily in C99, with parts of macOS support being written in
-Objective-C.  GLFW itself requires only the headers and libraries for your OS
-and window system.  It does not need any additional headers for context creation
-APIs (WGL, GLX, EGL, NSGL, OSMesa) or rendering APIs (OpenGL, OpenGL ES, Vulkan)
-to enable support for them.
-
-GLFW supports compilation on Windows with Visual C++ (2013 and later) and
-MinGW-w64, on macOS with Clang and on Linux and other Unix-like systems with GCC
-and Clang.  It will likely compile in other environments as well, but this is
-not regularly tested.
-
-There are [pre-compiled binaries](https://www.glfw.org/download.html) available
-for all supported compilers on Windows and macOS.
