cd22e28495 X11: Fix empty event race condition with a pipe
There is a seemingly unavoidable race condition when waiting for data on
the X11 display connection, as long as any other thread is also making
Xlib calls.  The event data we are waiting for could be read by the
other thread as part of looking for the reply to its request, before our
poll has begun.

This commit replaces the X11 event sent by glfwPostEmptyEvent with
writing to an unnamed pipe.  The race condition remains if other Xlib
calls are made on other threads, but glfwPostEmptyEvent should now be
race-free.

This commit is based on work by pcwalton, OlivierSohn, kovidgoyal and
joaodasilva.

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.

4ae93e0547 X11: Remove non-UTF-8 fallback paths
It seems it has not been possible to compile GLFW on systems without the
UTF-8 extensions to Xlib since a0a5cc57df
was merged five months ago.  The UTF-8 extension functions were
introduced with XFree86 4.0.2 in December 2000 and are likely widely
available at this point.

This removes the locale-dependent fallback paths and uses the UTF-8
extension functions where available.

9a3664b4a9 X11: Fix detection of key events duplicated by XIM
Background: The IM will filter out key events, instead sending exact
duplicate events that are not filtered.  It does not send these for
every event, however, so the duplicate events cannot be relied on for
key input.  Instead we need to identify and discard them.  Since they
are identical, they have the same timestamp as the originals.

The previous duplicate event detection would consume unrelated key
events if the keys were pressed simultaneously, as it only tracked
a single timestamp.

This fixes that issue for any combination of keys, at the expense of
a 1 KB array per GLFW window.

This fix is a stopgap until explicit IME support is done.

Based on #1472 by @LucaRood.

fe57e3c292 X11: Fix no window position events during resize
A window resize action that also resulting in the window being moved did

coordinates instead of root coordinates so this adds parent tracking and
conditional translation.

36f90800d8 X11: Query and keep track of Xkb group index
For users with multiple keyboard layouts configured, glfwGetKeyName
works fine only with the primary layout.  Switching layouts results in
changing the group index.  This commit querries the current group index
when initializing keyboard input and keeps track of any change to it.

As a result the scancode -> keyname mapping may change while the program
is running (needs to be documented).

29a75ab09d X11: Add native access to primary selection
This adds the native access functions glfwSetX11SelectionString and
glfwGetX11SelectionString under GLFW_EXPOSE_NATIVE_X11.  They are
similar to glfwSetClipboardString and glfwGetClipboardString but operate
on the PRIMARY selection.

The primary selection is widely used in X11, and so seems important to
support.  Primary selection is mostly an X11-specific thing, hence it's
exposed as an X11 native interface.

6a65341e14 X11: Fix multiple issues in XDND support
The code blindly expected UTF8_STRING for files.  It did not downgrade
based on source protocol version.  It did not handle hostnames in
text/uri-list data.  It did not specify the source time stamp when
converting the selection.  It did not search the XdndTypeList when
necessary.  It did not ignore sources that specified invalid versions.

While better, this is still not fully conformant.  Hostnames are not
validated and it does not guard against source crashes.
