Summary:
This has been commented out since 2014, I doubt it will come back.
This is a big amount of code, maintenance will be easier without it.

Summary:
Currently code base of kwin can be viewed as two pieces. One is very
ancient, and the other one is more modern, which uses new C++ features.
The main problem with the ancient code is that it was written before
C++11 era. So, no override or final keywords, lambdas, etc.
Quite recently, KDE compiler settings were changed to show a warning if
a virtual method has missing override keyword. As you might have already
guessed, this fired back at us because of that ancient code. We had
about 500 new compiler warnings.
A "solution" was proposed to that problem - disable -Wno-suggest-override
and the other similar warning for clang. It's hard to call a solution
because those warnings are disabled not only for the old code, but also
for new. This is not what we want!
The main argument for not actually fixing the problem was that git
history will be screwed as well because of human factor. While good git
history is a very important thing, we should not go crazy about it and
block every change that somehow alters git history. git blame allows to
specify starting revision for a reason.
The other argument (human factor) can be easily solved by using tools
such as clang-tidy. clang-tidy is a clang-based linter for C++. It can
be used for various things, e.g. fixing coding style(e.g. add missing
braces to if statements, readability-braces-around-statements check),
or in our case add missing override keywords.
Test Plan: Compiles.

This legacy session management scheme using the WM_COMMAND property
seems to be called XSM. It is very, very legacy because it was
superseded by XSMP in 1993(!).
By inspecting ~/.config/session/kwin_[...] I could see that Firefox
still sets WM_COMMAND, but nothing else in a regular session with
some applications.
As one of the last applications to switch to XSMP session management,
I guess Firefox keeps doing that because it still needs to work on,
say, Solaris, anyway, so why not set WM_COMMAND on Linux as well.
The WM_COMMAND set by Firefox looks like "wmCommand8=firefox\s" in
the kwin session file. It doesn't actually contain a session
identifier. But then, Firefox only has one session per user anyway.
This goes together with commit 5f0ca1305db4a925 in plasma-workspace /
ksmserver to remove legacy session management support.
I've talked about my plan to do this on IRC with Martin so hopefully
it's okay to just do this now.
All of kwin except the main function goes into a new (private) library
called kwin. Two new kdeinit_executables are created:
* kwin_x11
* kwin_wayland
Both only use a dedicated main_x11.cpp and main_wayland.cpp with the
main function and a KWin::Application subclass and linking the new
kwin library.
The main idea behind this is to be able to perform more sane sanity
checks. E.g. on Wayland we don't need to first test whether we can
create an X11 connection. Instead we should abort if we cannot connect
to the Wayland display. Also the multi-head checks are not needed on
Wayland, etc. etc. As most of that code is in the main function to
simplify it's better to split.
This will also make it easier to diverge more easily in future. The
Wayland variant can introduce more suited command line arguments for
example. This already started by having the --replace option only
available in X11 variant. The Wayland backend is still a window manager,
but doesn't claim the manager selection.
KSessionManager is deprecated and there is no replacement yet. So
let's get rid of the warnings for now. Needs to be re-added once
there is a working QSessionManager again.
This fixes build problems after 8f43c5e: sm.h would include
X11/SM/SMlib.h, which includes X11/ICE/ICElib.h, which adds a #define
Status int, which breaks qdeclarativeview.h, included by
moc_declarative.cpp.

and set by the user - they're now interchangeable. Which means
that Alt+F3/Advanced/No border can put the window decoration
back on the KRunner window regardless of what Plasma or any other
app thinks.

qdrawutil.h doesn't seem to have a purely Qt4-style equivalent, so including the directory there disambiguates it from the Qt3 header.
