The included fribidi header is not used in gdkkeys-wayland.c and already
included in gdk.c which causes linker issues due to the header defining
a global variable.
We currently calling gdk_display_map_keyval up to
once per key event per shortcut trigger, and that function
does an expensive loop over the entire keymap and
allocates an array. Avoid this by caching the entries
in a single array, and have a lookup table for finding
the entries for a keyval.
To do this, change the GdkKeymap.get_entries_for_keyval
signature, and change the ::keys-changed signal to be
RUN_FIRST, since we want to clear the cache in the class
handler before running signal handlers. These changes are
possible now, since keymaps are no longer public API.
Add all of the keyboard translation results in the key event,
so we can translate the keyboard state at the time the event
is created, and avoid doing state translation at match time.
We actually need to carry two sets of translation results,
since we ignore CapsLock when matching accelerators, in
gdk_event_matches().
At the same time, drop the scancode field - it is only ever
set on win32, and is basically unused in GTK.
Update all callers.
As far as possible, use per-display debug flags.
This will minimize the debug spew that we get from
the inspector if it is running on a separate display.
This patch makes that work using 1 of 2 options:
1. Add all missing enums to the switch statement
or
2. Cast the switch argument to a uint to avoid having to do that (mostly
for GdkEventType).
I even found a bug while doing that: clearing a GtkImage with a surface
did not notify thae surface property.
The reason for enabling this flag even though it is tedious at times is
that it is very useful when adding values to an enum, because it makes
GTK immediately warn about all the switch statements where this enum is
relevant.
And I expect changes to enums to be frequent during the GTK4 development
cycle.
Gtk+ treats MOD1 as a synonym for Alt, and does not expect it to be
mapped around, so we should avoid adding GDK_META_MASK if MOD1 is
already included to avoid confusing gtk+ and applications that rely on
that behavior.

NoSymbol is not a valid GDK symbol (it only has the concept of
VoidSymbol, for some reason, which is neither the same thing nor
produced by any sane keymap). Passing NoSymbol events through to GTK+
apps is unlikely to produce anything useful.
In particular, this meant VTE would scroll to the end of the buffer when
pressing Fn (required for Page Up/Down on Macs), as it was receiving a
keypress that wasn't a modifeir. This does not happen on X11, as the
KEY_FN keycode is above 255, so does not get sent to clients.

Since Wayland is using libxkbcommon, it inherits X unfortunate
real/virtual modifier distinction, so we have to do the same
gymnastics we do for X to map between the two.
This should fix matching of accelerators using virtual modifiers
(modulo gnome-shell bugs regarding the handling of Super).

GdkKeymap already has support for _get_num_lock_state() and
_get_caps_lock_state(). Adding _get_scroll_lock_state() would be good
for completness and some backends (Windows?) could take advantage of
this.
If the compositor sends a keymap that fails on "compilation",
xkb_keymap_new_from_string() returns NULL, which makes xkb_state_new()
crash when assuming there is a keymap.
In these cases, gdk must remain with a xkb_state to handle modifiers/keys
properly, so warn about the invalid keymap string, and keep the previous
keymap (currently initialized to "us")

The is_modifier field is supposed to be set if the key
would act as a modifier, not if any modifiers are currently
active. To fix this, introduce a private
_gdk_wayland_keymap_key_is_modifier function.
At the same time, make the hardware_keycode field in key
events actually contain the hardware keycode, not a copy
of the keyval.
The GDK model for keymaps expects the keymap object to stay
around and emit a ::keys-changed signal. So, do that. This
should make layout changes work, but it remains untested since
weston does not support layout changes at runtime.
At the same time, plug a memory leak where GdkWaylandKeymap
forgot to free its xkb objects in finalize.

libxkbcommon has had some changes to its API. However, it now has a
stable release (0.2.0), so this makes the necessary changes, and
replaces all uses of the deprecated API.

Review comment: I think the implementation of the vfuncs in gdkkeys-wayland.c
depend on that we're using the keysysm as the hardware keycode. I think that
needs to be evaluated for the future. But for now this patch gives reasonably
complete keyboard input.

This is then logically associated with the input device since each (keyboard)
input device has its own keymap.

Although GDK expects the keymap to be associated with the display under
Wayland this is really associated with the input device so expose this by
finding the first keyboard device.
