libweston: Add initial tablet support to weston
Introduces three new structs, weston_tablet and weston_tablet_tool for the respective devices, with the respective information as it's used on the protocol. And weston_tablet_tool_id to track the tools of a tablet. Note that tools are independent of tablets, many tools can be used across multiple tablets. The nesting on the protocol level requires a global tablet manager, a tablet seat nested into weston_seat. The list of tablets and tools are also part of the weston_seat. Most functions are stubs except for the actual tablet and tablet tool creation and removal. This is based on patches from Peter Hutterer <peter.hutterer@who-t.net> and Bastian Farkas <bfarkas@de.adit-jv.com>. Signed-off-by: Michael Olbrich <m.olbrich@pengutronix.de>
