bb9d699ae6 Share X11 fd polling logic with Wayland
This moves the X11 polling implementation to a separate file where it
can be used by either the X11 or Wayland backend or both.

This code should be POSIX compatible where necessary but will use the
lower latency but non-standard polling functions ppoll or pollts where
those are available.

This commit is based on work by OlivierSohn and kovidgoyal.

293d19a153 Wayland: Require xkbcommon 0.5.0 or greater
The Wayland backend now requires xkbcommon-compose, which was added in
version 0.5.0.  xkbcommon 0.5.0 was released in 2014.

This removes the non-composing fallback path for text input.

900848ad0c X11: Add extension header paths to CMake target
The way the X11 find module is written, these paths can differ from the
base X11 header path, even if they very rarely do.

76a5f781db Add glfwInitVulkanLoader
This removes the GLFW_VULKAN_STATIC CMake option and the
_GLFW_VULKAN_STATIC configuration macro and replaces them with the
glfwInitVulkanLoader function, allowing a single library binary to
provide both behaviors.

This is based on the design from PR #1374 by @pmuetschard.

Closes #1374

56a4cb0a3a Add runtime platform selection
This adds compile-time support for multiple platforms and runtime
detection of them.  Window system related platform functions are now
called from shared code via the function pointer struct _GLFWplatform.

The timer, thread and module loading platform functions are still called
directly by name and the implementation chosen at link-time.  These
functions are the same for any backend on a given OS, including the Null
backend.

The platforms are now enabled via CMake dependent options following the
GLFW_BUILD_<platform> pattern instead of a mix of automagic and ad-hoc
option names.  There is no longer any option for the Null backend as it
is now always enabled.

Much of the struct stitching work in platform.h was based on an earlier
experimental branch for runtime platform selection by @ronchaine.

Every platform function related to windows, contexts, monitors, input,
event processing and Vulkan have been renamed so that multiple sets of
them can exist without colliding.  Calls to these are now routed through
the _glfw.platform struct member.  These changes makes up most of this
commit.

For Wayland and X11 the client library loading and display creation is
used to detect a running compositor/server.  The XDG_SESSION_TYPE
environment variable is ignored for now, as X11 is still by far the more
complete implementation.

f5758d75d0 Remove context creation backend headers
These headers come from when GLFW only supported a single context
creation API at a time, chosen at compile-time.

Since EGL and OSMesa are now always enabled and the platform-specific
APIs are tied to their specific window system, there is no reason to
keep these declarations separate from the internal.h and *_platform.h
header files.

d83849792b Add override variable for CMake library type
This adds the GLFW_LIBRARY_TYPE CMake cache variable, which allows users
and higher-level projects to set what type of library GLFW is built as.

When not empty, this value overrides the standard BUILD_SHARED_LIBS
option for GLFW while still allowing it to control the type of other
libraries in a larger project.

This also allows building GLFW as an object library without adding dummy
source files (as required by Xcode) or producing unused library
binaries.

Projects using CMake 3.12 or later can link the resulting GLFW object
library normally using target_link_libraries.

dffe203c17 Wayland: Make libwayland-client dynamically loaded
The insight to use wayland.xml to resolve the difficult-to-redirect
interface symbols was gleaned from SDL.

Instead of compiling the code output of wayland-scanner separately it is
made part of the wl_init compilation unit.  This lets us do things like
transparently rename our copies of Wayland globals.

The OS version of wayland-client-protocol.h is no longer used by GLFW,
but it is presumably ABI compatible with the output of wayland-scanner.

111c02d74e POSIX: Remove use of deprecated gettimeofday
POSIX.1-2008 deprecated gettimeofday, which we used as a fallback if the
monotonic clock was unavailable.

This replaces that fallback with the non-monotonic real-time clock.

Because of the Gordian knot of feature test macros across Unices, this
also includes the shift from some platform source files defining
_POSIX_C_SOURCE to various values to _DEFAULT_SOURCE being defined for
all source files on Linux.  This is because -std=c99 on Linux disables
_DEFAULT_SOURCE (POSIX 2008 and extensions).

Once runtime platform selection comes in, this kind of platform-specific
preprocessor logic can be moved into the platform glue files and won't
need to be replicated by third-party build setups, but for now, sorry.

061a0263a9 Win32: Fix compilation with standalone LLVM
The /clang: suffix passed to Clang-CL was accidentally also passed to
the regular standalone Clang, which caused compilation to fail.  We now
pass /W3 to Clang-CL, which it interprets as -Wall.

The _CRT_SECURE_NO_WARNINGS macro is now defined for both Clang and
Clang-CL.

The /entry: flag passed to link.exe is now also passed to lld-link,
letting the windows subsystem tests and examples link.
