This removes the last dependency from plasma-framework on kde4support.
This change is a bit more involved than other kde4support removals because
QSharedPointer does not provide a count() method. I therefore reworked the code
to store the SharedSvgRenderer as a QWeakPointer in s_renderers, making it
possible to detect when the last one goes away by creating a QWeakPointer guard
in SvgPrivate::eraseRenderer().

Saves quite a lot of roundtrips to the XServer. Most important we
fetch the atom only once which means we don't have to refetch when
checking the property notify events.

Stop using classes from kde4support:
- KComponentData is deprecated, it will be using QCoreApplication::
applicationName() and QCoreApplication::applicationVersion(). Of course,
this means that the existing shells will have to be ported. I have no
problem with doing that port myself, if I'm told where to look into.
- Drop usage of KLocale, ported to QLocale
- Drop usage of KStandardDirs, ported to QStandardPaths
- Drop usage of KIcon, ported to QIcon
Furthermore, there's a module in src/declarativeimports/locale that IIUC
exposes KLocale bindings to QML. A specific plan to port it should happen
as well.

There's no need to make all the framework look for the QCA includes while
they're only being used by the remote part. It could possibly be made more
specific, but I don't think those are yet being used anyway.
This is in line with the frameworks naming policy, camelcasing. Up until
now, libplasma was the only library being KF5::plasma, that is now
KF5::Plasma.
Recently there's been some big changes in the ThreadWeaver API.
So big that they break the source compatibility we were supposed to
maintain, big time.
This patch tries to port plasma-framework to that new API.
