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.
Because EGL ties client API support to configs, attempts to create
a context with an unavailable client API will fail with the unhelpful
"failed to find suitable config" error description.
This attempts to detect cases where there are usable configs for the
other client API and emit a hopefully more helpful error.

We only care about displayable pixel formats (as defined in
WGL_ARB_pixel_format) for window context creation.
This changes pixel format enumeration to ignore non-displayable formats,
which are specified to be listed after displayable ones, by always using
the return value of DescribePixelFormat as the pixel format count.
On systems lacking the EGL_EXT_present_opaque extension, some
compositors treat any buffer with an alpha channel as per-pixel
transparent.
This commit ignores any EGLConfig with an alpha channel if the extension
is missing and the window is created with GLFW_TRANSPARENT_FRAMEBUFFER
set to false.
This is technically not a breaking change since GLFW_ALPHA_BITS is not
a hard constraint, but it is still going to inconvenience anyone using
the framebuffer alpa channel to store other kinds of data.

This adds window hints for the initial position, in screen coordinates,
of a window. The special value GLFW_ANY_POSITION means the window
manager will be allowed to position the window.
It is not possible to set window positions on Wayland and GLFW will
always behave as if these hints are set to GLFW_ANY_POSITION.

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.

The cursor theme was only loaded if the chosen seat had a mouse
(wl_pointer) during initialization. If a mouse was connected only after
glfwInit, there would be no cursor theme but the rest of the cursor
related code assumed one had already been loaded.
This also moves the details of cursor theme loading out into a separate
function to declutter platform init.
Because the original cursor theme loading code checked whether we got
a wl_shm, and because the rest of the code just assumes we have
a wl_shm, initialization will now fail if there isn't one.
Fixes#1450
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.
This fixes a regression introduced by
2c204ab52e. This broke the check for
whether there is already a GLFW joystick object for a given input
device, making it always fail.
