Martin Gräßlin a918591fef Use Logind to open/close devices needed by libinput
With libinput we have the problem that we need to have privileges to
open the device files. In order to not need wrappers or suid bits, we
use logind. This means that kwin_wayland has to be the session controler.

A LogindIntegration is added to connect to logind and wrap the dbus
calls. This is based on the logind integration done for ksld in
ksmserver. The LogindIntegration is started by Workspace and the
InputRedirection tries to become the session controller and starts the
libinput integration only after this succeeded.
