Due to being a compositor, kwin has to conform to some certain
interfaces. It means a lot of virtual functions and function tables to
integrate with C APIs. Naturally, we not always want to use every
argument in such functions.
Since we get -Wunused-parameter from -Wall, we have to plumb those
unused arguments in order to suppress compiler warnings at the moment.
However, I don't think that extra work is worth it. We cannot change or
alter prototypes in any way to fix the warning the desired way. Q_UNUSED
and similar macros are not good indicators of whether an argument is
used too, we tend to overlook putting or removing those macros. I've
also noticed that Q_UNUSED are not used to guide us with the removal no
longer needed parameters.
Therefore, I think it's worth adding -Wno-unused-parameter compiler
option to stop the compiler producing warnings about unused parameters.
It changes nothing except that we don't need to put Q_UNUSED anymore,
which can be really cumbersome sometimes. Note that it doesn't affect
unused variables, you'll still get a -Wunused-variable compiler warning
if a variable is unused.
This uses a sealed anonymous file (memfd) instead of a `QTemporaryFile`,
which is more efficient.
Ideally, this file was also reused if the keymap didn't change.

This makes KWin switch to in-tree copy of KWaylandServer codebase.
KWaylandServer namespace has been left as is. It will be addressed later
by renaming classes in order to fit in the KWin namespace.
modifiers request by the input method is supposed to send the raw
modifiers based on the keymap of the keyboard grabbed as result of the
grab_keyboard request. If input method client is not using the keysym
functionality it can decide to not send out the modifiers_map, since it
is already known to compositor as part of keymap event sent by it.
While at it also guard against empty modifiers_map, if this happens
ideally compositor should handle that information based on the keymap
sent out using grab_keyboard function, but since currently, we do not
have the grab_keyboard implemented in here, send out the NoModifier if
that happens.
- Drop the v0 support, it is no longer used by anything
- Adapt the text-input related methods in seat interface to include
versioning, this will be useful for when zwp_text_input_v3 support is
included in kwayland-server
- Refactor SeatInterface to get rid of globalTextInput, it is no longer
needed with the new approach
- Refactor out the ContentHints and ContentPurpose enums in separate
header file which can be shared by zwp_text_input_v2/3 implementation

We need to convert the content hint and content purpose to the
protocol values before passing it to the input method since text-input
v0, v2 and v3 have a different values for some of enums. We need to do
manual translation.
If a client attempts to create an input panel surface for a wl_surface
that already has a role assigned, we must post a protocol error or else
the behavior of the input panel surface will be undefined.
Posting an error of 0 is not really correct, but on the other hand the
spec has no any error enums.
