Summary: The Device class wraps all the information we can get from libinput about the device, like whether it's a keyboard, pointer, touch, etc. In addition some more information is queried to figure out how "useful" a device is. For a keyboard all alphanumeric keys are checked whether they exist, for a pointer all (normal) buttons are queried. All the information is exposed as Q_PROPERTY and used by the DebugConsole. The DebugConsole gained a new tab "Input Devices" which renders all devices and their properties in a tree view. When plugging in/out a device, the model gets reset, so it's always up to date. The new Device class can be used in future to configure the device, e.g. disable touch pad, set mouse acceleration, etc. Reviewers: #plasma Subscribers: plasma-devel Projects: #plasma Differential Revision: https://phabricator.kde.org/D1538
