1fb9f6f13a Switch to SPDX license markers
The main advantage of SPDX license identifiers over the traditional
license headers is that it's more difficult to overlook inappropriate
licenses for kwin, for example GPL 3. We also don't have to copy a
lot of boilerplate text.

In order to create this change, I ran licensedigger -r -c from the
toplevel source directory.

cc862fa674 [focuschain/task switcher] Remove special handling for minimized windows
Right now KWin moves minimized windows to the end of the task switcher's
ordering. However this is a rather confusing and undocumented behavior
that explicitly overrides the user's chosen sort ordering, be it
"Recently used" or "Stacking order". This makes it a hidden magic behavior
of the type that is at risk of being more annoying than useful.

This commit removes the special handling and lets minimized windows live
in the appropriate order in the task switcher.

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.

fe7a6834b2 FocusChain operates on AbstractClient instead of Client
As external interface it still returns Client* to not force the casts
to be done at usages. This will be changed once the users are migrated
to AbstractClient*.

7747a38189 step into the focus chain at the beginning
if the index is 0, we close the circle, but if the
index is -1 (invalid) we're "somewhere" and step
into the focus chain - reasonably at the beginning

edb074cbc2 Split out screen handling from Workspace into own class Screens
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.

0fb27fd12e Defines to create the boilerplate code for KWin's singleton classes
The define KWIN_SINGLETON adds to a class definition:

public:
    static Foo *create(QObject *parent = 0);
    static Foo *self() { return s_self; }
protected:
    explicit Foo(QObject *parent = 0);
private:
    static Foo *s_self;

There is an additional define KWIN_SINGLETON_VARIABLE to set a different
name than s_self.

The define KWIN_SINGLETON_FACTORY can be used to generate the create
method. It expands to:

Foo *Foo::s_self = 0;
Foo *Foo::create(QObject *parent)
{
    Q_ASSERT(!s_self);
    s_self = new Foo(parent);
    return s_self;
}

In addition there are defines to again set a different variable name and
to create an object of another inheriting class.

All the classes currently using this pattern are adjusted to use these
new defines. In a few places the name was adjusted. E.g. in Compositor
the factory method was called createCompositor instead of create.

4a0a4bc27e Split out handling of focus chain into an own 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).
