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). REVIEW: 107494

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. REVIEW: 109865

* @brief Singleton class to handle the various focus chains.
*
* A focus chain is a list of Clients containing information on which Client should be activated.
*
* Internally this FocusChain holds multiple independent chains. There is one chain of most recently
* used Clients which is primarily used by TabBox to build up the list of Clients for navigation.
* The chains are organized as a normal QList of Clients with the most recently used Client being the
* last item of the list, that is a LIFO like structure.
*
* In addition there is one chain for each virtual desktop which is used to determine which Client
* should get activated when the user switches to another virtual desktop.
*
* Furthermore this class contains various helper methods for the two different kind of chains.

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*.

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). REVIEW: 107494

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. REVIEW: 109865
