The EGL backend ignored the state of GLFW_DOUBLEBUFFER and always
created a double-buffered EGL window.
This sets the EGL_RENDER_BUFFER attribute at EGL window creation
appropriately.
Fixes#1843.
This adds support for EGL_EXT_platform_base and its associated X11 and
Wayland extensions, allowing us to explicitly tell EGL which window
system we are using.
This is based on work by @linkmauve in #1691.
Closes#1691.
As of the release of Mir 1.0, libmirclient has been deprecated[1] and
its developers recommend clients using it to switch to Wayland. This
patch removes support for libmirclient and instruct users to use the
experimental Wayland backend instead.

Inclusion of internal headers is already both centralized and follows
strict rules. Inclusion guards are both an unneccessary maintenance
burden and may hide inclusion order bugs.
PFN_FunctionName is more readable than SCREAMSOUP_T.
Context creation API function typedefs are kept as-is where the original
header provided them, for compatibility and familiarity reasons.
If EGL_KHR_get_all_proc_addresses extension is supported, then don't try
to load a separate client library. Instead, just use eglGetProcAddress
to load everything.
This can also avoid problems with trying to use OpenGL functions from
libGL.so.1 (which is the GLX library) when an EGL context is current.
Closes#871.
Added GLFW_INCLUDE_VULKAN. Added glfwVulkanSupported,
glfwGetRequiredInstanceExtensions, glfwGetInstanceProcAddress,
glfwGetPhysicalDevicePresentationSupport and glfwCreateWindowSurface.
Added port of LunarG SDK tri example.
Removed compile-time selection of GLX entry point retrieval mechanism.
Made dlopen a required dependency.
This is a stopgap solution until we start requiring GLX 1.4.
