5ccc756c56 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.

65fc4fa625 X11: Fix sonames for loaded libraries on OpenBSD
The OpenBSD ports tree assigns its own soname version numbers, so the
hardcoded sonames GLFW uses to load libraries on non-macOS Unices are
often incorrect.  Instead OpenBSD recommends that run-time loading
should leave out the version numbers entirely.  The OpenBSD ld.so then
finds the correct library.

This upstreams the ports tree fixes for Xcursor and EGL, and adds the
corresponding fix for all other run-time loaded library sonames.

Tested on OpenBSD 7.0.

This issue was initially reported on IRC.

11e5102d83 Use the correct type in a for loop
The `atomCount` variable has the type `unsigned long`,
so the `for` loop iterating over it should use the same type.

Closes #1701.

404c28df3d X11: Improve non-XKB fallback for key mapping
A regression introduced by b889aa7841
broke the special handling of numpad keys for the non-XKB fallback path.
The non-functional remains were later removed.  This restores the
original behavior.

b25ee390c1 X11: Fix function keys mapped to GLFW_KEY_UNKNOWN
This fixes the issue where function keys would be reported as
GLFW_KEY_UNKNOWN if XKB was available and one of the configured keyboard
layouts was Arabic.

This is only part of #1598, because the full patch removed parts of the
fallback path for when XKB is unavailable.

Closes #1598.

399c082033 X11: Fix content scale fallback value on KDE
KDE sometimes removes the Xft.dpi resource when it would be set to the
X11 default value of 96, causing GLFW to fall back to a value calculated
from the core display sizes in pixels and mm in a desktop environment
that supports Xft.dpi.

This moves to a hardcoded fallback value of 96 on the assumption that
there are more people running KDE with 96 DPI than there are people
running desktop environments that do not support Xft.dpi.

All of this is terrible please send help.

Fixes #1578.

b3eb6dd38b 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).

Fixes #1462.
Closes #1528.

e276f6731e X11: Clean up EWMH feature detection
The EWMH feature detection atoms are now named and loaded the same way
as other X11 atoms.  Detection is now performed after all
non-conditional atoms have been loaded.  The EWMH detection now has
hopefully more readable comments.

3a2a97f15d X11: Fix implementation of work area retrieval
This intersects the global work area from _NET_WORKAREA with the monitor
viewport.  The monitor viewport falls back to the core display
dimensions where working RandR is missing.  The _NET_WORKAREA query is
now checked for success.  The _NET_WORKAREA extent array is now indexed
by _NET_CURRENT_DESKTOP.  The _NET_WORKAREA atom is now checked for
availability.

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.

Fixes #894.
Closes #1056.
