The group names are forced by check (they are called suite names there) but
for our test suite they provide very little benefit. Much easier to just
use the filename a test is in as group name.
This removes the pure substring match for --filter-group, it's now fnmatch
only. group names are short enough that the typing isn't an issue and we don't
want to run tests twice (e.g. 'pad' is also in 'touchpad').

litest itself requires the libinput user_data to be set to its own context
struct (see close_restricted). A test that needs its own user_data must not
override this struct - if the context is accessed during libinput_dispatch()
we'll get memory corruption.

Data in
https://gitlab.freedesktop.org/libinput/libinput/-/issues/225#note_379034
suggests that AES devices have lower noise than the older EMR
devices, so let's try disabling it for those devices.
We can't directly get the AES devices in libinput unless we want to add a
whole bunch of quirks for the various vid/pid combinations. But we can get
that info from libwacom, primarily because we know that libwacom will list all
known AES pens for any device. So we can check for one that we know of (0x11)
and if it's in the list, the tablet is an AES tablet.
Setting the history size to 1 means we never do any actual smoothing.

The current tool type test merely sends BTN_TOOL_RUBBER (and others) manually
and expects libinput to do the right thing. This only tests the perfect
sequence but not test weird devices that behave differently on a tool type
switch.
So let's fix this by setting the tool type as property on the libinput test
device itself, and then emulate the tool switch through litest.
For special devices this will need extra callbacks, this is just the initial
framework to handle those buttons.

With the previous patches a tablet would ignore a valid proximity out sequence
where it happends after a forced prox-out. Fix this by checking the state when
we're in forced proximity out - if we have a zero tool state but a tool
updated then we did get a proximity out.

This quirk was introduced for #248 was caused by buggy input-wacom drivers,

This appears to be the only tablet where this fix was needed, but we've been
playing whack-a-mole ever since to work around the various other tablets that
break with this behavior in place.
So let's revert that fix and hope there aren't any other tablets out there
(and if they are, we can probably quirk those). The revert makes the ISDV4 pen
quirk obsolete (see 9cb089f2b6), so this was
folded into this commit.

Where a pen was forced out of proximity and an eraser came into proximity
without axis updates on the prox-in, subsequent axis updates would trigger the
pen back into proximity. This resulted in two tools in proximity at once
though the new pen never went out of proximity
This would trigger crashes in various compositors/applications, see
https://github.com/xournalpp/xournalpp/issues/1141#issuecomment-578362497
The cause was a wrong condition introduced in ffd8c71e4e. We only need to
force the pen bit on if the current tool state is currently zero and no tool
update was sent with the axis event. In our case, the tool state is nonzero
already (eraser) and we can skip this bit.

Some graphics tablets (most or all Wacom, for example) do not emit
proximity out events when the tablet pen goes out of range. To
compensate for this, libinput synthesizes proximity out events when no
events are received for a certain period of time. Unfortunately, on some
tablets, this is fairly failure prone when moving the pen slowly. As a
workaround, this patch causes libinput to avoid synthesizing proximity
out events when the pen is still in contact with the tablet pad, as
defined by the TABLET_TOOL_IN_CONTACT status.
Pens that don't have a pressure offset (caused by a worn-out tip) still have
basic pressure thresholds to avoid tip events when we're still a bit away from
the tablet or barely touching it. That range is currently 5% of the pressure
for tip down, 1% for tip up.
This leaves us with 95% of the range and that needs to be scaled correctly,
otherwise the bottom 5% happen before a tip event and are inaccessible where
applications don't look at pressure before tip down.

Previously, the pressure range was calculated from the axis total range. A
device with a pressure offset making the bottom 10% inaccessible would lose
10% of that range as non-accessible. Due to the implementation, this affected
the upper range of the device, so the top N percent became unaccessible. Which
may be why no-one's noticed this yet.

Unsuprisingly, a normalized [0,1] value will always be between 0 and 1, so
bhis gave us a false positive. Check for the real values instead.
Those values aren't 100% correct because of a bug in the offset handling which
will be fixed in a follow-up commit. The difference is near enough that it
doesn't matter here anyway.

We keep running into the proximity timeout for these tests, especially under
valgrind. To avoid this, manually intersperse the touch events with tablet
events.
Note that this manual loop would just work even without tablet events
because we no longer have a 10ms delay between touch events as enforced by
litest_touch_move_to. But let's do the right thing anyway.

This pen has random timeouts, often when a button is pressed. This causes a
forced proximity out (and the button release) and makes the whole device a
tad unusable.
Nothing we can detect by heuristics since it looks like other devices that
don't send proximity out events. And the timeout can be quite high, the
recording in #304 has over 800ms for one sequence.

an extra proxmity in-out after the forced proximity out event.
Event sequence is basically (k: kernel, l: libinput)

l: tablet axis events
k: nothing for $proximity timer milliseconds
l: tablet proximity out
k: proximity out event

This device looks similar to a MT device on the kernel side, but it's not a
MT device and it's not quite a tablet either. It uses slots to track up to 4
totems off the same device and the only hint that it's not a MT device is that
it sends ABS_MT_TOOL_TYPE / MT_TOOL_DIAL.
udev thinks it's a touchscreen and a tablet but we currently init those
devices as touchscreen (because all wacom tablet touch devices are udev
tablets+tochscreens). So we need a quirk to hook onto this device.
And we use a completely separate dispatch implementation, because adding the
behavior to the tablet interface requires so many exceptions that it's easier
to just add a separate dispatch interface.

Unlike virtually everything else, the tablet tool was processed at the time
the event was read rather than when the subsequent EV_SYN came in. This causes
difficulties with tablets that send the wrong BTN_TOOL_PEN events.
Moving the tool change processing to tablet_flush() makes the injection of the
BTN_TOOL_PEN event a lot easier, simply flipping the matching bit does the
job. It also makes it easier to ignore duplicate tool updates like we've seen
in #259.
