This panel is not very friendly to us:
it exposes multiple multitouch collections, some of them being of
logical application stylus.
Usually, a device has only one report per application, and that is
what I assumed in commit 8dfe14b3b47f ("HID: multitouch: ditch mt_report_id")
To avoid breaking all working device, add a new class and a new quirk
for that situation.

It was a good idea at the time to not create a mouse node for the
multitouch touchscreens, but:
- touchscreens following the Win 8 protocol should not have this
disturbing mouse node anymore, or if they have, it should be
used for something else (like a joystick attached to the screen)
- touchpads have it, and they should not use it unless there is a bug,
but when the laptop has a trackstick, the data are reported through this
mouse node.
So instead of whitelisting all of the devices that have a need for the
mouse node, just export it.
hid-input.c will append a suffix to it ('Mouse'), so users will eventually
see if something goes wrong.

Since kernel v5.0, one single win8 touchscreen device failed.
And it turns out this is because it reports 2 InRange usage per touch.
It's a first, and I *really* wonder how this was allowed by Microsoft in
the first place. But IIRC, Breno told me this happened *after* a firmware
upgrade...
Anyway, better be safe for those crappy devices, and make sure we have
a full slot before jumping to the next.
This won't prevent all crappy devices to fail here, but at least we will
have a safeguard as long as the contact ID and the X and Y coordinates
are placed in the report after the grabage.

commit f07b3c1da92d ("HID: generic: create one input report per
application type") was effectively the same as MULTI_INPUT:
hidinput->report was never set, so hidinput_match_application()
always returned null.
Fix that by testing against the real application.
Note that this breaks some old eGalax touchscreens that expect MULTI_INPUT
instead of HID_QUIRK_INPUT_PER_APP. Enable this quirk for backward
compatibility on all non-Win8 touchscreens.

Usually, there is no palm rejection for touchscreens. You don't rest
your palm on the touchscreen while interacting with it.
However, some wacom devices do so because you can rest your palm while
interacting with the stylus.
Unfortunately, the spec for touchscreens[1] is less precise than the one
for touchpads[2]. This leads to a situation where it's 'legitimate'
for a touchscreen to provide both tipswitch off and confidence off in the
same report.
Work around that by keeping the slot active for one frame where we report
MT_TOOL_PALM, and then synthesizing the release event in a separate frame.

According to Microsoft specification [1] for Precision Touchpads (and
Touchscreens) the devices use "confidence" reports to signal accidental
touches, or contacts that are "too large to be a finger". Instead of
simply marking contact inactive in this case (which causes issues if
contact was originally proper and we lost confidence in it later, as
this results in accidental clicks, drags, etc), let's report such
contacts as MT_TOOL_PALM and let userspace decide what to do.

The Dell Canvas 27 has a tool that can be put on the surface and acts
as a dial. The firmware processes the detection of the tool and forward
regular HID reports with X, Y, Azimuth, rotation, width/height.
The firmware also exports Contact ID, Countact Count which may hint that
several totems can be used at the same time (the FW only supports one).
We can tell that MT_TOOL_DIAL will be reported by setting the min/max
of ABS_MT_TOOL_TYPE to MT_TOOL_DIAL.
This tool is aimed at being used by the system and not the applications,
so the user space processing should not go through the regular touch
inputs.
We set INPUT_PROP_DIRECT which applies ID_INPUT_TOUCHSCREEN to this new
type of devices, but we will counter this for the time being with the
special udev hwdb entry mentioned above.

The current way of handling multitouch data is not very straightforward:
- in mt_event() we do nothing
- in mt_report() we:
- do some gym to fetch the scantime and the contact count
- then iterate over the input fields where we copy the data to a
temporary place
- when we see the last field in a slot, we then use this data to emit
the input data
A more streamlined way is to first get all of the address in the report
of all fields, and then just pick the fields we are interested in in
mt_report()

According to [1] and also seemingly agreed by [2], the Scan Time usage
(0x0D 0x56) is a report level usage, not a contact level usage.
However, the hid-multitouch driver currently includes HID_DG_SCANTIME
when calculating `td->last_slot_field', which may lead to
mt_complete_slot() being prematurely called in certain cases (e.g. when
each touch input report includes more than one contact and the Scan Time
usage appears before any contact logical collection).
This patch fixes the issue by skipping mt_store_field() on
HID_DG_SCANTIME, similar to how HID_DG_CONTACTCOUNT and
HID_DG_CONTACTMAX are handled.

The Win8 spec also declare other features we want to support:
latency and surface and button switches.
Though it doesn't seem we need to activate those by default, we have been
proved in the past that manufacturers rely on the Windows driver behavior
so we better mimic it to prevent further issues.
The current way of setting the features is cumbersome. It avoids iterating
over the list of features, but the way we store/retrieve the data just
doesn't scale with more than two values.
So iterate over the features when we decide to switch on the device and
make it simpler to extend.

We now have HID_QUIRK_INPUT_PER_APPLICATION that splits the devices
into several devices. This helps us as we can now rely on hid-input
to set the names for us.
Also, this helps removing some magical numbers '0' when calling
.input_configured().
The only thing to take care of is that the field .report in struct
hid_input is now null. We need to iterate over the full list of
reports attached to a hid_input.
This is required for some Advanced Silicon touchscreen to correctly apply
the HID_QUIRK_INPUT_PER_APPLICATION as they have 2 reports associated
with the hidinput node. One contains the Input data, the other one
contains the Output data.

According to the Win8 Precision Touchpad spec, inside the HID_UP_BUTTON
usage-page usage 1 is for a clickpad getting clicked, 2 for an external
left button and 3 for an external right button. Since Linux uses
BTN_LEFT for a clickpad being clicked we end up mapping both usage 1
and 2 to BTN_LEFT and if a single report contains both then we ended
up always reporting the value of both in a single SYN, e.g. :
BTN_LEFT 1, BTN_LEFT 0, SYN. This happens for example with Hantick
HTT5288 i2c mt touchpads.
This commit fixes this by not immediately reporting left button when we
parse the report, but instead storing or-ing together the values and
reporting the result from mt_sync_frame() when we've a complete frame.

Devices in "single finger hybrid mode" will send one report per finger,
on some devices only the first report of such a multi-packet frame will
contain a value for BTN_LEFT, in subsequent reports (if multiple fingers
are down) the value is always 0, causing hid-mt to report BTN_LEFT going
1 - 0 - 1 - 0 when pressing a clickpad and putting down a second finger.
This happens for example on USB 0603:0002 mt touchpads.
This commit fixes this by only reporting non touch fields for the first

The Windows Precision Touchpad spec "Figure 4 Button Only Down and Up"
and "Table 9 Report Sequence for Button Only Down and Up" indicate
that the first packet of a (possibly hybrid mode multi-packet) frame
may contain a contact-count of 0 if only a button is pressed and no
fingers are detected.
This means that a value of 0 for contact-count is a valid value and
should be used as expected contact count when it is the first packet
(num_received == 0), as extra check to make sure that this is the first
packet of a buttons only frame, we also check that the timestamp is
