Handle everything which is not handled by the tap, (soft)button or edge-scroll
code/statemachines in a unified way. Everything is treated as a X-finger
gesture now, and the action to take on finger movement is decided by
the gesture.finger_count setting. Pointer control now simply is seen as a
1 finger gesture, and 2fg scrolling as a 2fg gesture.
This removed the need for special-casing things like switching back to
pointer mode when lifting a finger in 2fg scrolling mode, and also lays the
groundwork for adding 3+ fg gesture support.
Note that 1 test-case needs to be updated to wait for the finger mode
switching when switching mode while a gesture has already been started.
This is actually an improvement as this stops sending spurious pointer
motion events at the end of 2fg scrolling when not lifting both fingers at
exactly the same time.

Add edge-scrolling support for non multi-touch touchpads as well as for
users who prefer edge-scrolling (as long as they don't have a clickpad).
Note the percentage to use of the width / height as scroll-edge differs from
one manufacturer to the next, the various per model percentages were taken
from xf86-input-synaptics.

Currently we are using DIY timers in the touchpad softbutton and tap handling
code, and at least the softbutton code gets its wrong. It uses one timer-fd
per touchpad to set a timeout per touch, which means that if a timeout is
set for 100ms from now for touch 1, and then 50 ms later touch 2 sets a timeout
for 200 ms from now, then the timeout for touch 1 will come 150 ms too late.
This commits adds a proper timer subsystem so that we've one place to deal
with timer handling, and so that we can only get it wrong (well hopefully
we get it right) in one place.

libevdev wraps the various peculiarities of the evdev kernel API into a
type-safe API. It also buffers the device so checking for specific features at
a later time is easier than re-issuing the ioctls. Plus, it gives us almost
free support for SYN_DROPPED events (in the following patch).
This patch switches all the bit checks over to libevdev and leaves the event
processing as-is. Makes it easier to review.

This patch ports udev-seat from weston to libinput, including adapting
libinput internals and API to provide seat and device discovery.
The public API is extended with device discovery, object reference, a
seat object. As libinput takes care of creating and destroying its
objects user data getter/setter is added in order to make it possible
for the client to directly associate an object application side with an
object library side.
Device discovery API is made up of the 'seat added', 'seat removed',
'device added' and 'device removed' events. The seat added/removed
events contains a pointer to a libinput_seat struct, while the device
added/removed events contains a pointer to a libinput_device event.
The objects are reference counted with libinput holding one reference by
default. The application can increase the reference count with
libinput_seat_ref() and libinput_device_ref() and decrease the reference
count with libinput_seat_unref() and libinput_device_unref().
The basic event struct is changed to have a 'target' union parameter
that can be either a libinput, libinput_seat or libinput_device struct
pointer.
There is one known problem with the current API that is the potentially
racy initialization.
The problem is when a device is both discovered and lost during initial
dispatchig, causing libinput to first queue a 'added' message, creating
the device with default reference count 1, then before going back to the
application queuing a 'removed' message, while at same time decreasing
reference count of the device to 0, causing it o be destroyed. The queue
will at this state contain two messages with pointers to free:ed memory.

Instead of having the user manage added and removed fd's as well as the
fd used for creating evdev devices, introduce a libinput object that
itself has an epoll fd.
The user no longer manages multiple fd's per libinput instance, but
instead handles one fd, dispatches libinput when data is available, then
reading events using libinput_get_event().
libinput_event's are now per libinstance, but divided into categories.
So far the only category is device events. Device events are categorized
by the presence of a non-NULL device pointer in the event.
The current API usage should look like:
struct libinput libinput = ...;
struct libinput_event *event;
if (libinput_dispatch(libinput) != 0)
return -1;
while ((event = libinput_get_event(libinput))) {
if (event->device)
process_device_event(event);
free(event);
}

This commit introduces build script configuration for building a shared
library 'libinput.so' containing the evdev input device functionality
from weston.
evdev.c, evdev.h and evdev-touchpad.c are ported to not use the data
structures and API in weston and libwayland-server in order to minimize
dependencies.
The API of filter.c and filter.h are renamed to not include the
'weston_' prefix.
