These are all internal API so having a NONE value means we can shut up
warnings about 0 not being an enum value without having those exposed in
our public API.
And they slightly improve readability in the callers anyway.

In a valiant approach to introduce some type-safety (after spending time
debugging a int vs double confusion) this adds a DECLARE_NEWTYPE()
macro that declares a named struct with a single typed value field.
This is basically the C version of Rusts "struct Foo(u32)" with
a few accessors auto-generated by the macro.
C is happy to silently convert between base types but it doesn't do
so for structs so this allows us to have some type safety
when we accidentally assign two incompatible fields to each other (e.g.
an axis value in device units vs a percentage value).

Instead of having this ifdef'd out split the main and directly
associated functions out into a separate file.
That ifdef used to exist so we can use parts of litest in some other
files (the selftest and the utils test). Those tests care mostly
about the assertion helpers so long-term a split into
assert helpers and "rest of litest" would be better. For now, this will
do.

Commit 48cd4c7287 ("tablet: track pressure ranges per tablet") added
up to 4 per-tablet pressure ranges that are stored in the tool on the
assumption that tools are never used across more than 4 tools.
However, if the tablet gets unplugged it will show up as new devices.
Fix this by removing the tool's reference to the previous tablet after
device removal.

When the tool is moved in proximity of a new tablet but the pressure
range hasn't changed since the last proximity, the new tablet was left
with a threshold range of 0:0.
For some reason this requires tightening up the check for the test too,
with our default episolon 0.091 fails the test of being > 0.9

Modifies an existing proximity test to also test for the case where a
tablet never sends BTN_TOOL_PEN so we have that case covered.
This is implicitly tested by the LITEST_UCLOGIC_TABLET test device but
making it explicit is a bit easier to debug.

A tablet with multiple mode toggle buttons had each mode toggle button
merely cycle to the next mode in the sequence, removing the whole point
of having multiple toggle buttons.
Fix this by defaulting each mode toggle button to "next". Once we
have initialized all buttons we can check if we have multiple buttons -
if so we number them sequentially so that the first button maps to mode
0, the second maps to mode 1, etc.

This was working on an assumption that there is only one ref of the
tablet tool and if we call unref it will be removed. This assumption is
not something we can guarantee in the public API so we shouldn't test
for it.
Part-of: <https://gitlab.freedesktop.org/libinput/libinput/-/merge_requests/1161>
This avoids inconsistencies between the LITEST_ enum value and the
shortname but also makes it easier to grep for any test cases that use
the same define. At the cost of the test names not looking very nice
anymore but oh well.

Tablets may have different ABS_PRESSURE ranges with the oldest tablets
having 1k pressure range, then 2k, and the newer ones 8k.
If the same tool is used across two tablets with different ABS_PRESSURE
ranges, the first tablet in proximity calculated the range on where to
normalize to. As a result the other tablet either couldn't reach the
full pressure (2k pressure first, then 8k) or the full pressure range
was reached at a fraction of the full range (8k pressure first, then
2k).
Fix this by moving the threshold handling into a separate struct and
hardcoding up to 4 of those per tool. That is 2 more than the more
complicated setups I've heard of (and this only applies to tracking the
same stylus across those tablets anyway).
This duplicates the pressure offset heuristics but that's easier than
figuring out how to handle heuristics across potentially two tablets.
The range configuration is left as-is on the assumption that this one is
per tool, not per tablet.

touchpad_move_after_touch contains support for up to 5 fingers but was only run
with 2..4 fingers.
touchpad_multitap and several others using the same parameter definition were
long ago tested with 3..7 taps. In 8f92b091 this was reduced to 3..4 for CI
performance, while the commit message indicates 3..5 were intended.
The common theme is that the upper bound of `struct range` is interpreted
as exclusive, while some uses assumed it would be inclusive.
There are relatively recent helper functions range_init_inclusive and
range_init_exclusive (since 817dc423) to avoid this trap. Use them on the
remaining two ranged tests.
Part-of: <https://gitlab.freedesktop.org/libinput/libinput/-/merge_requests/1142>
The two remaining ranged tests (abs_device_no_range, abs_mt_device_no_range)
are better served staying with ranges because parametrized tests need to
explicitly list all members of the range, which for these tests is not only
pretty big, but also contains abs axes reserved for future use. Those axes
have no names yet, making a future-proof conversion pretty much impossible.

Exposed via new configuration option this enables 3 and 4 finger
dragging on touchpads. When enabled a 3/4 finger swipe
gesture is actually a button down + motion + button up sequence.
If tapping is disabled the drag starts immediately, if tapping is
enabled the drag starts after the tap timeout/motion so we can distinguish
between a tap and a drag.
When fingers are released:
- if two fingers remain -> keep dragging
- if one finger remains -> release drag, switch to pointer motion
When 3/4 fingers are set down immediately after releasing all fingers
the drag continues, similar to the tap drag lock feature. This drag lock
is not currently configurable.
This matches the macos behavior for the same feature.

The 5th finger was placed in the same position as the 4th finger which
doesn't have an effect in libinput but it looks wrong.
And the first finger was put down at 40/30 but then moved from 70/30 to
the new position, causing pointer jumps on some touchpads.

Require the type to be added in the litest_test_params_fetch() so we can
easily detect a mismatch. And add some type-safe getters that are much
easier to use for all the tests that only have a single parameter to
fetch anyway.

Slightly less efficient but easier to read and it's not possible to
accidentally provide the wrong length. Plus it handles null pointers
correctly so get to skip the checks (which weren't needed for strneq()
either, but still).

The previous invocation was gated behind a TABLET_OUT_OF_AREA check
resulting in a nonresponsive tool when the tablet was moved out of
proximity outside the tablet area and the area was changed.
Move the actual status bit changes up into tablet_flush()
so we unconditionally set those.
