Adds all internal ShellClients into a dedicated list. This ensures that
we don't perform "normal" window management on them.
In addition we add them to the top of the stacking order. This restores
behavior as it is on X11: internal windows are using BypassWindowManagerHint
and thus on top of everything.
Windows that "belong" to the desktop are
kept visible and do no break the state on
activation/mapping

Moves the properties and the base implementation into AbstractClient.
Methods invoke a new protected virtual method which is implemented in
Client to update the TabGroup.
This is an alternative approach suggested by the
NETWM spec.
The advantage is, that windows are not minimized
at all what apparently lead to some confusion
about the nature of the mode (which was abused
to tidy up) and a secret config key to allow for
that unrelated behavior.
Instead the ShowDesktopIsMinimizeAll key is removed
and replaced by a dedicated script + shortcut.
Bonus: less code to remember "minimized" windows =)
when restacking for shaded windows and uncomposited tabboxes
the group check should not be applied since we know better
eg. to restore a former order

Callgrind analysis showed that this method has room for improvement.
The bottle neck is mapping the Unmanaged against the list of windows
retreived from xcb_query_tree. The number of windows in that list is
rather large (>1000), which turns the loop into an expensive path.
Workspace::findUnmanaged seems to be too expensive for that due to the
overhead of using a functor and multiple method calls. The Inl. cost
before the optimization for checking ~55,000 windows is 2.46.
The change uses a good old const-iterator based loop over the unmanaged
list to check for the window. This reduces the Incl. cost for checking
~55,000 windows to 0.28.

The build option got introduced for Plasma Active back in a time
when we did not properly aim for convergence. In a Plasma 5 world
we want to have only one shell and one window manager which adjust
itself. This means we don't want a differently compiled kwin for
plasma active, but the same one. Thus the build option doesn't
make much sense any more. A KWin for touch interface needs to support
screenedges for the case that mouse is plugged in.

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.

Instead of passing the macro based Predicate to findUnmanaged it now
expects a function which can be passed to std::find_if.
Existing code like:
xcb_window_t window; // our test window
Unmanaged *u = findUnmanaged(WindowMatchPredicated(window));
becomes:
Unmanaged *u = findUnmanaged([window](const Unmanaged *u) {
return u->window() == window;
});
In addition an overload is added which takes the window id to cover
the common case to search for an Unmanaged by its ID. The above example
becomes:
Unmanaged *u = findUnmanaged(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

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.

For all the decoration updates called from Client into the decoration we
also have a signal being emitted. So turning the pure virtual public
functions into slots means we can just connect our existing signals and
get rid off the deep function calls.
The keepAbove/Below signals are changed to take a boolean argument as
needed by KDecoration and a few emitted signals are moved to a better
fitting location.

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.

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.

Following the approaches of other split out functionality Screens is a
singleton class created by Workspace.
The class takes over the responsibility for:
* screenChanged signal delayed by timer
* number of screens
* geometry of given screen
* active screen
* config option for active screen follows mouse
The class contains a small abstraction layer and has a concrete subclass
wrapping around QDesktopWidget, but the idea is to go more low level and
interact with XRandR directly to get more detailed information.
All over KWin the usage from QDesktopWidget is ported over to the new
Screens class.

The new class FocusChain manages two different kind of focus chains.
First of all there is a most recently used focus chain which is primarily
used for TabBox.
Then there is one focus chain per virtual desktop. These chains are used
to determine which Client needs to be activated when e.g. switching to a
virtual desktop.
The individual chains are implemented as a simple QList of Client* with
the most recently used Client as the last element. That way one can see
it as a LIFO like structure.
The desktop focus chains are internally represented as a hash with the id
of the virtual desktop as the key and a list as described as the value.
FocusChain is a singleton which provides some methods to manipulate the
chains and to get a specific Client for a task (e.g. TabBox).
While splitting out the code some unused code inside TabBox got removed
as well as some activities related code (windows cannot be moved while
switching activities).

In fact it already used to be a Singleton as there is just one object
hold by the Singleton Workspace. So let's make it a proper Singleton
following our kind of standard approach of having a ::create factory
method called from Workspace ctor and a ::self to get to the singleton
instance.
This rewrite is mostly motivated by the need to handle multi screen
setups correctly. That is have edges per screen and not for the combined
geometry. Also porting from XLib to XCB has been a motivation for the
rewrite.
The design of the new ScreenEdge handling is described in the
documentation of ScreenEdges in screenedge.h.
In addition the following changes have been performed:
* move configuration from Options to ScreenEdge
* add screen edge information to Workspace::supportInformation (obviously
replaces what had been read from Options)
* have Workspace hold a pointer to ScreenEdges instead of an object
* forward declaration of ScreenEdges in workspaces.h, this explains the
seemingly unrelated changes of just another include in some files

The ownership for virtual desktops is moved from Workspace into a new
VirtualDesktopManager. The manager is responsible for providing the count
of virtual desktops and keeping track of the currently used virtual
desktop.
All methods related to moving between desktops are also moved from
Workspace to the new manager, though all methods related to Clients on
Virtual Desktops remain in Workspace for the time being. This is to have
the new manager as independent from KWin core as possible.
An rather important change for the handling of virtual desktops is that
the count and the id of a desktop is now an unsinged integer instead of
an integer. The reason for that is that we cannot have a negative count
of desktops as well as it is not possible to be on a desktop with a
negative identifier.
In that regard it is important to remember that a Client can be on a
desktop with a negative identifier. The special value for a Client being
on all desktops is handled by using -1 as a desktop. For the time being
this is not adjusted but instead of comparing the virtual desktop ids one
should prefer to use the convenient methods like isOnDesktop and
isOnAllDesktops. This would allow in future to internally change the
representation for on all desktops.
It is not used anywhere inside KWin at all and the DBus method is not
used anywhere inside KDE's repositories (according to lxr). Because of
that marked as deprecated and going to die with Qt 5.
