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.

9d4a32596c Drop some custom list typedefs
Summary:
Qt has its own thing where a type might also have corresponding list
alias, e.g. QObject and QObjectList, QWidget and QWidgetList. I don't
know why Qt does that, maybe for some historical reasons, but what
matters is that we copy this pattern here in KWin. While this pattern
might be useful with some long list types, for example

    QList<QWeakPointer<TabBoxClient>> TabBoxClientList

in general, it causes more harm than good. For example, we've got two
new client types, do we need corresponding list typedefs for them? If
no, why do we have ClientList and so on?

Another problem with these typedefs is that you need to include utils.h
header in order to use them. A better way to handle such things is to
just forward declare a client class (if that's possible) and use it
directly with QList or QVector. This way translation units don't get
"bloated" with utils.h stuff for no apparent reason.

So, in order to make code more consistent and easier to follow, this
change drops some of our custom typedefs. Namely ConstClientList,
ClientList, DeletedList, UnmanagedList, ToplevelList, and GroupList.

Test Plan: Compiles.

ec610fd7ed Port one of session management connections state to a custom API
Summary:
Currently kwin opens a second ICE connection to ksmserver in order to
tell the state of kwin's whether we're logging out and saving clients or
not.

This requires that kwin launches after ksmserver to have the connection
which is a dependency I want to break.

Practically this code is already ksmserver specific as it relies on some
custom code that sends the first saveState request to kwin first.

Instead we can replace it with a bespoke IPC over DBus and siplify the
code both end. This will allow several other future enhancements that we
want with regards to handling the session state, as well as make an
effort platform agnostic session management, as well as cleaning up some
complex code.

Ksmserver calls into kwin, rather than having kwin watch ksmserver state
to allow us make sure it's race free.

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.

684b4b635e Use more traditional doxygen style
Summary:
So far we were following a bit unique and rare doxygen comment style:

    /**
     * Contents of the comment.
     **/

Doxygen comments with this style look balanced and neat, but many people
that contribute to KWin don't follow this style. Instead, they prefer
more traditional doxygen comment style, i.e.

    /**
     * Contents of the comment.
     */

Reviewing such changes has been a bit frustrating for me (so selfish!)
and for other contributors.

This change switches doxygen comment style in KWin to a more traditional
style. The main reason for doing this is to make code review process easier
for new contributors as well us.

2693e288c5 Avoid potential assert in SM saving
Summary:
Sesison Manager stores all relevant clients. There's an assert if the
window type is outside of the standard client window types. It assumed
that all windows outside this would be Unmanaged windows rather than
Client objects, something probably true but not something enforced.

This particular crash was probably cased as we have a new window type in
Plasma OSD, which does not set BypassWindowManager in Qt window flags.

750843061c fix showing of window on inactive activities during session save
This is what 7ce380497f tried to do (and got reverted by my previous commit).
The approach is basically the same, just temporarily fake that the window
is on all activities, thus it will be temporarily shown for the session
interact, but this time there seem to be no broken side-effects (and if there
are, they'll be at least limited to activities and not break virtual desktops).
Also, 'needsSessionInteract' was a misnomer - it certainly wasn't set for all
windows that needed session interaction. Just call it what it really is.

2eac7634cc Remove saving and loading (and client matching by) WM_COMMAND.
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.

da85b5fdc7 Split out Activities related code from Workspace
All activities related code moves into new singleton class Activities.
This class gets only included into the build if the build option is
enabled which means there are less ifdefs all over the code and it also
handles better the moc doesn't like ifdef case.

The class holds the list of open and all activites, the current and the
previous activity and the KActivities::Controller. It also emits the
signals for any activities related changes.

Workspace still contains some activities related code. That is the
adjustment on change of current activity. Nevertheless the code looks
much cleaner now and does not contain the confusing naming conflict with
takeActivity() which existed before.

In all the places where Activities got used the code got adjusted and
quite often the ifdef got added with a fallback for the disabled case.

334b4bf622 Move handling of Virtual Desktops into a VirtualDesktopManager
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.

a394fade64 Remove Tiling support from KWin
As discussed on the mailinglist [1] the tiling support is
removed from KWin. The main reasons for this step are:
* it is unmaintained
* it is a mode not used by any of the core KWin team
* original developer said at Akademy 2012 that he is not
  interested in picking up the work again
* tiling has quite some bugs, e.g. multi screen not supported
* is conflicting with other concepts in KWin, e.g. activities

There is ongoing work to get tiling supported through a KWin
script, which is a preferred way as it does not influence the
existing C++ code base.
