All callers except the tap motion threshold call
tp_get_delta() followed by tp_filter_motion() - the latter normalized it
before calling into the accleration code.
Move the normalization into tp_get_delta() so we don't deal with
device-specific coordinates but normalized deltas instead.

On one test we can just swap the release order, the other test we need to

And merge all current API versions into the same block. This isn't technically
necessary since removing libinput_has_button from the code will remove it from
the exported list. That trips up test/symbols-leak-test though.
Since we break the API and bump the soname in this release anyway, move
to a single block so the initial stable API is all nicely grouped together.

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.

With the upcoming gesture support 2fg scrolling will be handled as part of

machine, our current way of dispatching scroll "actions" does not play well
with this.
Change the scroll method handling to treat edge and 2fg scrolling as 2
separate state machines. The double scroll calls this introduces will mostly
be removed when the gesture handling code lands.

The easiest way to get a device group is by looking at the phys path of the
input device (which looks like usb-0000:00:14.0-1/input1) and dropping the
/inputX bit. The rest is the same for devices that belong together (except on
the Cintiq 22HD Touch).
Ideally we could just take ATTRS{phys} but we can't select substrings to drop
into ENV so we need to do it ourselves. This patch adds a callout that takes a
syspath and prints the mangled path, to be used in LIBINPUT_DEVICE_GROUP.
The rule triggers on any device that has a non-zero phys attribute, this
groups devices like tablets together but also devices like mice with multiple
interfaces.

Use ID_INPUT_FOO to assume a device is a FOO, don't decide ourselves based on
whatever bits are available. This moves the categorization out to udev's
input_id builtin by default and other bits that tag the device. libwacom tags
all known devices as ID_INPUT_TABLET and (for touch-enabled ones)
ID_INPUT_TOUCH - we can re-use that knowledge then.
Ignore anything that doesn't have ID_INPUT set, this provides for an easy way
of making devices "invisible" to libinput.

udev already tags the devices by opening each of them and analyzing their
features. We are basically re-doing this in libinput.
The advantage of udev tags over the plain heuristic from libinput is that
users (or driver writers) can force some tags that are not detected by
common rules. For instance, the pad part of the Wacom tablets is difficult
to discriminate from a joystick or a pointer.
For now we tread INPUT_ID_KEY and INPUT_ID_KEYBOARD as equivalent. It may
become necessary to separate them later.

Signed-off-by: Peter Hutterer <peter.hutterer@who-t.net>
Devices like Wacom tablets have multiple event nodes (touch, pad and stylus).
This requires some logical grouping, e.g. setting an Intuos 5 tablet
left-handed effectively turns it upside down. That then applies to both the
stylus and the touch device.
Merging the devices into one struct libinput_device is not feasable, it
complicates the API for little benefit. A caller would still need access to
all subdevices to get udev handles, etc. Some configuration options apply to
the whole device (left-handed) but some (may) only apply to a single subdevice
(calibration, natural scrolling).
Addressing this would make the libinput API unwieldly and hard to use.
Instead, add a device group concept. Each device is a member of a device
group - a singleton for most devices. Wacom tablets will have a single group
across multiple devices, allowing the caller to associate the devices together
if needed.
The API is intentionally very simple and requires the caller to keep track of
groups and which/how many devices are in it. The caller has more powerful
libraries available to do that than we have.
This patch does not address the actual merging of devices into the same
device group, it simply creates a new group for each new device.
