Summary: The LibInput::Device provides a way to enable/disable the device. This is used by the Connection to toggle all touchpad devices on/off when the touchpad key is pressed. For this KWin "steals" the global shortcuts from the touchpad kded. Detecting what is a touchpad is unfortunately not tivial. The code uses the following approach: * it's a pointer * it's not also a keyboard or touch screen * it's at least one of the following: ** supports multiple tap fingers ** supports disable while typing ** supports disable on external mouse If the code finds a touchpad and changes it's state successfully, it triggers the touchpadEnabledChanged on Plasma's osdService. Test Plan: Tested on notebook with toggle touchpad button Reviewers: #plasma Subscribers: plasma-devel Projects: #plasma Differential Revision: https://phabricator.kde.org/D1545
