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.

When in EVDEV_RELATIVE_MODE, after converting the absolute valuators, the

events on these valuators would be lost.

The Xen Virtual Pointer device has ABS_X, ABS_Y and REL_WHEEL. If smooth
scrolling is detected, the current code would first initialize relative axes
for scrolling and immediately overwrite those axes when the abs valuators are
written out.
This patch fixes the default case only, in the case of a device setting the
two Ignore*Axis options both to "off", the axes are still overwritten. The
wheels will work, other axes only if the same number of abs axes exists. And
it keeps the current memory leak too, but it's marked with a FIXME now.

The previous approach only had the slot state for the current slot. If we
changed slots, that means we lost the information if the slot was ever
initialized. If the ABS_MT_TRACKING_ID was never received, the slot would
still update and try to send events (which the server refused with a warning).
Avoid this by having a per-slot state and a dirty bit that tells us if the
current slot updated at all. If we don't get the tracking ID, leave the slot
empty and refuse any further events from that touch.
This quashes the various "unable to find touch point 0" warnings caused if a
touchpoint starts before the device is enabled.

EvdevAddDevice/EvdevRemoveDevice keep a reference to the device to detect
duplicate devices based on the dev_t.
EvdevAddDevices was called during PreInit, EvdevRemoveDevice was called during
DEVICE_CLOSE. That makes it imbalanced if the device succeeds PreInit but the
server skips everything else because MAX_DEVICES is exceeded. So for all
devices after MAX_DEVICES, we'd add a reference but never remove it,
eventually reading/writing past evdev_devices.
The server keeps the list of devices for us anyway, so remove the copy of all
the pointers and instead run through the device list the server gives us.

Note that touch 2 has the same X and Y position as touch 0. This is
implied because no new value was emitted for slot 0. In fact, Linux will
not emit an event in the same slot with the same event type and code
unless the value has changed. Thus, we can only assume that all the MT
valuators have the same values as they were when they were last sent for
the given slot.
This change adds an array of valuator mask to hold all the last valuator
values that came from evdev for each slot. When a new touch begins, all
the last values are copied into it.
This patch assumes initial axis values of 0 in each slot. Linux and
mtdev do not provide a facility to query the current values of axes in
each slot yet. This may cause spurious incorrect touch valuator values
at the beginning of an X session, but there's nothing we can do about it

After we swap the axes, we only call valuator_mask_set for axes that are
not zero, so we need to unset the axes that became zero when swapped.

We were correctly swapping the valuator values, but we were not
calling valuator_mask_unset() when needed, so the cursor kept jumping
to the edges.
This patch does the swapping before the main "for", so we don't need to
store unswapped_{x,y} and unswapped_isset_{x,y} even when we don't need
to swap.

ABS_MT_SLOT comes before any other events. The following order of events
is common for protocol B devices (and mtdev):
...
EV_SYN
ABS_MT_SLOT → posting here means we miss on the position information
ABS_MT_POSITION_X
ABS_MT_POSITION_Y
ABS_MT_SLOT
ABS_MT_POSITION_X
ABS_MT_POSITION_Y
EV_SYN
Store the stot state as SLOT_EMPTY after posting an event (i.e. EV_SYN and
ABS_MT_SLOT) and then don't post until the next slot/syn event.

This causes evdev to handle these device as a mouse rather than a
touchscreen, which naturally doesn't work very well. We already internally
translate BTN_TOUCH as BTN_LEFT, so accept this kind of devices as
touchscreens by checking for devices with BTN_LEFT, absolute X/Y and NO
relative X/Y axes.

On some keyboards, the multimedia function keys are overlaid with the F
keys. This property enables clients to switch the primary mode of these F
keys between function keys and multimedia keys.
Some keyboards provide an Fn key to toggle between the modes. This is
hardware-specific and may or may not work on any given keyboard device.
The current imlementation is only hooked up to apple keyboards.
The kernel provides a tweak to enable/disable.
/sys/module/hid_apple/parameters/fnmode
0 .. keyboard sends Fx keys, Fn disabled
1 .. keyboard sends multimedia keys, Fn toggles to function keys
2 .. keyboard sends function keys, Fn toggles to multimedia keys

For touchpads, rel_queued may be on (due to abs to rel conversion) but the
delta for x/y is 0/0 on the first touch. Hence, we don't have any valuators
to post. The current results in a num_vals of -15 and a subsequent segfault
when the data is posted to the server.
Start with a last valuator of -1, so that we know if we have at least one to
post.

Touchpads send garbage data between BTN_TOOL_FINGER and BTN_TOUCH. This
leads to cursor movement towards invalid positions (bottom left corner,
usually).
Add a new flag "use_proximity" as a delimiter for BTN_TOUCH handling. If
unset, the actual proximity bits are ignored, no proximity events are sent
and BTN_TOUCH is used for the tool handling.
