A GLFW_CURSOR_UNAVAILABLE error would be emitted each time the cursor
moved over the fallback decorations if the standard cursor shape
appropriate for that part was missing on the system.
These errors served no useful purpose and have been removed.
This is partly based on the implementation of libdecor support in
PR #1693 by @ christianrauch.
Where available, the libdecor library is loaded at init and becomes the
preferred method for window decorations. On compositors that support
XDG decorations, libdecor in turn uses those. If not, libdecor has
a plug-in archtecture and may load additional libraries to either use
compositor-specific decorations or draw its own.
If necessary, support for libdecor can be disabled with the
GLFW_WAYLAND_LIBDECOR init hint. This is mostly in case some part of
the dynamic loading or duplication of header material added here turns
out to cause problems with future versions of libdecor-0.so.0.

This commit simplifies the detection of which element of a fallback
decorated window the pointer has entered. Instead of looping through
the list of windows, the user pointer of fallback decoration surfaces is
set to the GLFW window object.
This replaces (one case of) manual management of weak links between
windows and monitors, both objects with complex life times, with
wl_object pointers used as opaque key values.
This is in preparation for adding support for libdecor, which creates
its own proxies on our display. It will likely also be helpful to some
people using native access on Wayland.
This is partly based on the implementation of libdecor support in
PR #1693 by @ christianrauch.
If a window was initially fullscreen then it would not get an XDG
decoration object. If the window was later switched to windowed mode it
would then get fallback decorations instead of XDG ones.
This adds a window hint string for the xdg_toplevel::app_id, which is
used by desktop environments to connect windows with application icons
and other information. This is similar to the WM_CLASS property on X11.
A few very minor fixes were done by @elmindreda during merge.
Fixes#2121Closes#2122
If the key or character callback performs actions that indirectly
updates the key repeat timer, those changes would be undone once the key
callback returned.
This fixes the order of operations so that key repeat is fully set up
before the key related events are emitted.
