ffcbe24e2b Rename Client to X11Client
Summary:
Currently each managed X11 client is represented with an instance of
Client class, however the name of that class is very generic and the
only reason why it's called that way is because historically kwin
was created as an x11 window manager, so "Client" was a sensible choice.

With introduction of wayland support, things had changed and therefore
Client needs to be renamed to X11Client in order to better reflect what
that class stands for.

Renaming of Client to X11Client was agreed upon during the last KWin
sprint.

Test Plan: Compiles, the test suite is still green.

62a7db7028 Use nullptr everywhere
Summary:
Because KWin is a very old project, we use three kinds of null pointer
literals: 0, NULL, and nullptr. Since C++11, it's recommended to use
nullptr keyword.

This change converts all usages of 0 and NULL literal to nullptr. Even
though it breaks git history, we need to do it in order to have consistent
code as well to ease code reviews (it's very tempting for some people to
add unrelated changes to their patches, e.g. converting NULL to nullptr).

Test Plan: Compiles.

ce1a5eae15 Support NET_WM_STATE_FOCUSED
Summary:
This is used by GTK clients to know whether to draw as though they have
focus or not. Whilst it's most visible for CSDs headers, use of the
active/inactive palette (or backdrop class in GTK terms) applies
everywhere.

Rationale of the flag is to allow the WM to hint visual states without
giving input, i.e so you can hint that the parent of a modal dialog
should be shown as active. Though kwin only sets it on the truly active
window to match the behaviour our other windows follow.

BUG: 398832

I expect this to be potentially controversial as it's new code in X11,
so in advance:

* Unlike GTK_FRAME_EXTENTS, it is part of the specificiation (albeit
1.4) even i3 supports it.

* It does fix a real world issue

* It's only 2 lines (plus trivial boiler plate in kwindowsystem)

* It's in code path that we rely on for our existing code

* If there's a situation where this does break, the worst that will
happen is a client gets a visual hint to have focus incorrectly, which
ultimately is the same as the current state

Test Plan:
Used my CSS for breeze-gtk
moved between windows

Revert "Add "SkipSwitcher" to API"
This reverts commit 8a2a00a4ca.

It was likely wrongly pushed before the KWayland changes, so it won't
compile.

Feel free to reinstate it once the dependent changes (KWayland) are in.

0455fa9ef9 Only send active window changes to X11 root window if the X11 window changed
Summary:
So far KWin always updated the active window property even if the actual
window id hasn't changed. E.g. if a Wayland window was active and another
Wayland window gets activated the window id was and stays 0.

Nevertheless KWin updated the property causing wakeups in X server and
any application listening to property changes on the root window.

Futhermore this situation is an information leak: we leak when a Wayland
window gets activated to X11.

To solve this problem RootInfo caches the active window id and only
updates if it changes.

Test Plan:
Verified with xev -root that the active window does not get
updated needlessly.

1d9769af1f Move skipTaskbar from Client to AbstractClient
At the same time the functionality for the "original_skip_taskbar" is
splitted out. This removes the weird API with two boolean arguments to
the set method. Instead there is a dedicated method for the orignal
skip taskbar state which delegates to regular skipTaksbar.

0030eb7f84 Initial import of support for new KDecoration2 based decorations
NOTE: this is not working completely yet, lots of code is still ifdefed
other parts are still broken.

The main difference for the new decoration API is that it is neither
QWidget nor QWindow based. It's just a QObject which processes input
events and has a paint method to render the decoration. This means all
the workarounds for the QWidget interception are removed. Also the paint
redirector is removed. Instead each compositor has now its own renderer
which can be optimized for the specific case. E.g. the OpenGL compositor
renders to a scratch image which gets copied into the combined texture,
the XRender compositor copies into the XPixmaps.

Input events are also changed. The events are composed into QMouseEvents
and passed through the decoration, which might accept them. If they are
not accpted we assume that it's a press on the decoration area allowing
us to resize/move the window. Input events are not completely working
yet, e.g. wheel events are not yet processed and double click on deco
is not yet working.

Overall KDecoration2 is way more stateful and KWin core needs more
adjustments for it. E.g. borders are allowed to be disabled at any time.

bc0a9cb53a [kwin] Use std::find_if and lambda functions for Workspace::findClient
Instead of passing the macro based Predicate to findClient it now
expects a function which can be passed to std::find_if.

Existing code like:
xcb_window_t window; // our test window
Client *c = findClient(WindowMatchPredicated(window));

becomes:
Client *c = findClient([window](const Client *c) {
    return c->window() == window;
});

The advantage is that it is way more flexible and has the logic what
to check for directly with the code and not hidden in the macro
definition.

In addition there is a simplified overload for the very common case of
matching a window id against one of Client's windows. This overloaded
method takes a Predicate and the window id.

Above example becomes:
Client *c = findClient(Predicate::WindowMatch, w);

Existing code is migrated to use the simplified method taking
MatchPredicate and window id. The very few cases where a more complex
condition is tested the lambda function is used. As these are very
local tests only used in one function it's not worthwhile to add further
overloads to the findClient method in Workspace.

With this change all the Predicate macro definitions are removed from
utils.h as they are now completely unused.

970e8765f0 [kwin] Remove support for _NET_WM_TAKE_ACTIVITY protocol
As can be seen in [1] the patches to KWin were in CVS HEAD before the
protocol got standardized and it never got any adoption. It's neither in
the NETWM spec, nor implemented in Qt4 nor in Qt5. KWin did not even add
the protocol to the NET::Supported property.

Thus it doesn't make much sense to keep a protocol which nobody speaks.

Still the code around the protocol is kept and also the names are kept.
Only difference is that Client::takeActivity got removed and the code
moved to the only calling place in Workspace. Motivated by that change
the enum defined in utils.h is moved into Workspace, it's turned into
a proper QFlags class and used as a type in the method argument instead
of a generic long.

b6681ddc3a Turn RootInfo into a KWIN_SINGLETON
It's not a typical singleton as the ctor is not taking a Workspace* and
needs addtional data to be passed to NETRootInfo.

All the initialization code is moved to RootInfo::create() and the tear-
down code is moved to RootInfo::destroyed(). This includes the support
window which used to be a member of Workspace. It's only needed by
RootInfo, so there is no need to have the ownership inside Workspace.

Instead of using a QWidget we just create a normal window through xcb.
It gets destroyed again in the tear-down code after the RootInfo got
destroyed.

db18c08dd0 Move RootInfo and WinInfo into an own header and impl file
Main motivation for this change is that it's unhandy to have the class
definition in workspace.h and client.h while the implementation is in
events.cpp although nothing in events.cpp uses it directly.

By getting it out of workspace.h we get the header a little bit smaller
which should improve compile time given that it's included almost
everywhere.

In events.cpp the enum usage is changed to NETWinInfo as that's the class
where they are defined.

RootInfo does no longer hold a workspace pointer. Where it's needed it
uses the singleton accessor of Workspace.
