Invoking xf86PostProximityEvent with no valuators does nothing, so we
have to provide a valid valuator set to the call.

[whot: slight change from 104562
abs_vals is reset on every frame but old_vals is kept around to remember the
last value of the valuator (and is updated to the current values before
processing the frame). We expect the prox in to have x/y, so let's just
unconditionally use old_vals for proximity events.]

Wacom tablets send a farewell reset to 0 on all axes when the tool goes out of
proximity. Ignore those so we can rely on our various valuator masks always
having the correct coordinates.
Possible false positive if you manage to go out of proximity right above the
zero datum but meh.

When transforming 'only buttons' device into a pseudo-mouse by adding
relative X and Y axes, EVDEV_RELATIVE_EVENTS flag must be set on device,
otherwise it gets classified as a keyboard by X11.

Updating abs_vals for touch events since d24431a186
leads to posting Motion events with updated coordinates to the X server,
which in turn resends them to clients.
Don't queue Motion events for touch events, the X server should
synthesize them itself.

Sometimes it may be desirable to remap physical middle button
to something else and use emulation instead. The emulation is
however hardcoded to emulate physical button 2, so the emulated
button gets remapped together with the physical one. This patch
adds the Emulate3Button configuration option to allow for user
selection of the emulated button number and a configuration
like this:
Section "InputClass"
Identifier "Middle button emulation config"
MatchProduct ".... some device ..."
MatchDriver "evdev"
Option "Emulate3Buttons" "on"
Option "Emulate3Button" "9"
EndSection

This broke in d24431a186 Restore wheel emulation for absolute devices,
last hunk when the valuator update was moved to before any early exit
condition. But that new update only applies to valuator maps < 2, i.e. x/y
only. Other valuators are now ignored and remain on 0 forever.
Restore the valuator update.

The idea was that of a direction lock: as we move vertically we should not
build up any horizontal scroll motion even if we move slightly diagonally.
The effect was though that the axis would be reset completely as soon as an
event from the other axis occured. With the default threshold of 10, if one in
ten events was a REL_X, we'd never get a wheel event.
Drop this code, it's not needed. By default wheel emulation doesn't do
horizontal scrolling, if a config snippet sets XAxisMapping the user wants
horizontal scrolling. And since we just add the value anyway, as long as the
user does a roughly vertical motion we won't get over the threshold anyway.

Wheel emulation relies on oldVals, which stopped updating in 3dcf6f123c.
Since wheel emulation may filter the abs event, store the event before we do
anything with it. If we really want the abs_event, abs_queued will be set to
1, otherwise the value will be ignored.
And now that we know abs_value is always valied, we can copy its value into
old_vals, so that wheel emulation can calculate the delta correctly.

First, it's not actually inertia, it's simply the scroll distance, yay for the
misnomer.
And it needs to be set for any device that is more fine-grained than a
mouse, especially absolute devices. For example the VirtualBox device has an
abs max of 32767, so a simple motion may have a delta of to 2000 units and
that results in 200 scroll events. That's a bit excessive.

The Logitech G600 has one device with all axes north of ABS_MISC. The current
code assigns ABS_MISC as first axis to map to axis 0, i.e. x. On button press,
one node sends the BTN_LEFT but the other node sends an ABS_MISC with a 1 0
value. ABS_MISC is mapped to axis 0, this moves the pointer to (0, y) on
every button click.
Avoid this by simply mapping any axis other than x/y to at least axis 3, and
make sure we only override the MT 0/1 axes when we actually have MT axes.

It can be used to scale the resolution of a mouse to that of a 1000 DPI
mouse. This can be useful to make high resolution mice less sensitive
without turning off acceleration. The target of 1000 DPI is used as the
same default is used in libinput. If the option is not set no scaling
will be done.

When in EVDEV_RELATIVE_MODE, after converting the absolute valuators, the
code unsets pEvdev->abs_queued. This is wrong if there are some absolute
valuators which are not positions, such as a pressure valuators, because
events on these valuators would be lost.
This patch fixes the problem by doing the absolute->relative translation
early. This way, abs_queued is not set and then unset when receiving
absolute valuators representing positions. Other absolute events now set abs_queued
and will be processed.

When not in EVDEV_RELATIVE_MODE, absolute position is stored in old_vals. This serves
no purpose except that old_vals is ready when the device is switched to
EVDEV_RELATIVE_MODE. It is however better to make the copy between old_vals
and abs_vals at the time of the switch rather than all the time.

When not in_proximity, we don't really trust data, even though a valuator
sent just before a in_proximity event might actually be important. The
present code for EVDEV_RELATIVE_MODE throws away all data if not
in_proximity, which is a little bit too much. This patch allows for
relative values to be calculated and old_vals to be updated even if not
in_proximity, but will prevent evdev to sending (presumably) wrong
information to the X server. But at least, old_vals will be correctly
filled when the device comes into proximity again.
