Reorganize evdev plugins
linuxinput becomes evdevmouse. The experimental touch code is removed, now the plugin's purpose is solely to generate mouse events from absolute and relative pointer events. The plugin key is EvdevMouse. touchscreen becomes evdevtouch. The plugin key is EvdevTouch. In case keyboard support appears some day, it will fit nicely in the system by the name of evdevkeyboard or similar. Some little udev code is moved to platformsupport so it can be shared between the plugins. This may be extended later if more sophisticated udev support is needed. N.B. the intention is to keep this as simple as possible. We are shipping these plug-ins as reference examples, not as full-featured drivers. evdev and udev support has configure time tests from now on. This means the "drivers" (generic plugins) will get built automatically when the support is available.

-Generic plug-in for evdev touch events.
-
-Tested with the following drivers: bcm5974, hid_magicmouse.
-
-(1) Using as a QPA generic plug-in
-
-1. set up and connect the touch device
-2. install libudev-dev or similar
-3. build this plug-in (qmake && make)
-4. sudo cp 70-qtouchscreen.rules /etc/udev/rules.d
-5. sudo udevadm trigger --subsystem-match=input
-6. ./fingerpaint -plugin LinuxTouchScreen:force_window
-
-If automatic detection does not work, use -plugin
-LinuxTouchScreen:/dev/input/eventN to explicitly set the device file
-name.
-
-By default the surface of the touch device is mapped to the entire
-screen. If this is not desired, pass force_window in the plugin
-specification as shown in the example above. This will cause mapping
-the touch surface to the active window instead.
-
-Only touch events are generated, mouse events are not. Be aware however
-that ignored touch events will generate a mouse event from the first
-touch point by default. See AA_SynthesizeMouseForUnhandledTouchEvents.
-
-(2) Using in a compositor
-
-The classes (QTouchScreenHandler, QTouchScreenHandlerThread) are also
-suitable for direct inclusion into an application, e.g. a Wayland
-compositor. The compositor may then register its own
-QTouchScreenObserver because relying on the QTouchEvents generated by
-the QPA event sender may not always be satisfactory as some low-level
-details get lost, and due to performance reasons.
-
-(3) Possible issues and solutions
-
-The udev rule matches any touchpad device. If there are multiple ones,
-specify the device as described above.
-
-If no evdev events are read, remove 50-synaptics.conf (or similar)
-from /usr/share/X11/xorg.conf.d and restart X. Or at least temporarily
-disable the device by running xinput set-prop <device> <device enabled
-property> 0. Use xinput list and xinput list-props to figure out the
-values.
