Use iconName instead of sending a fixed-size pixmap around, fix wording and use title
capitalization, more meaningful names in notifyrc, QStringLiteral and new style connect.

This meant to add a lot of dependencies to each plugin since we had
KDELibs4support as PUBLIC link meaning that anything linking against
kdeconnectcore was linking at the same time to mostly all frameworks.
Now each plugin has more or less its dependencies in the CMake some
still depend on KDELibs4Support.
For the mousepad plugin I needed to add a fixX11.h file that basically
undefines/defines again some stuff xlib has that conflcits with normal
C++ and Qt.
Before it was not conflicting because some lib within KDELibs4Support
was including this file, but now we have to do it ourselves.
I had to keep the old kDebug code in kdebugnamespace because other parts
of the code are using it. Will be removed as soon as all code using it
is ported as well.
Only lets the plugins that support something offered on the other end or
that offer something supported on the other end. If we don't have
information about the other device, we enable everything like we used to.
Also refactors a bit the plugin loader, to be able to provide information
step by step.
Currently it works, but we need support for capabilities at least on
Android to start taking good advantage of it.

Ported using KDELibs4Support, for a smaller delta, so we can keep
developing on master until we decide not to.
At the moment, it builds and installs but tests don't pass because
of a QCA2 initialization problem I didn't manage to debug yet.
