terminal: add input interface
The idev-interface provides input drivers for all libsystemd-terminal based applications. It is split into 4 main objects: idev_context: The context object tracks global state of the input interface. This will include data like system-keymaps, xkb contexts and more. idev_session: A session serves as controller for a set of devices. Each session on an idev-context is independent of each other. The session is also the main notification object. All events raised via idev are reported through the session interface. Apart of that, the session is a pretty dumb object that just contains devices. idev_element: Elements provide real hardware in the idev stack. For each hardware device, one element is added. Elements have no knowledge of higher-level device types, they only provide raw input data to the upper levels. For example, each evdev device is represented by a different element in an idev session. idev_device: Devices are objects that the application deals with. An application is usually not interested in elements (and those are hidden to applications), instead, they want high-level input devices like keyboard, touchpads, mice and more. Device are the high-level interface provided by idev. Each device might be fed by a set of elements. Elements drive the device. If elements are removed, devices are destroyed. If elements are added, suitable devices are created. Applications should monitor the system for sessions and hardware devices. For each session they want to operate on, they create an idev_session object and add hardware to that object. The idev interface requires the application to monitor the system (preferably via sysview_*, but not required) for hardware devices. Whenever hardware is added to the idev session, new devices *might* be created. The relationship between hardware and high-level idev-devices is hidden in the idev-session and not exposed. Internally, the idev elements and devices are virtual objects. Each real hardware and device type inherits those virtual objects and provides real elements and devices. Those types will be added in follow-up commits. Data flow from hardware to the application is done via idev_*_feed() functions. Data flow from applications to hardware is done via idev_*_feedback() functions. Feedback is usually used for LEDs, FF and similar operations.
