At least on the t440, this is enough to trigger correct detection between
pinch and scroll 90% of the time. Since scrolling is significantly more
prevalent than gesturing, erring on the side of scrolling at the cost of
misdetecting some gestures is acceptable.

Behavior for axis events in the same event frame as the BTN_TOUCH is to
always send axis events before any tip state.
Behavior for button events in the same event frame as the BTN_TOUCH is to
order button events to happen when the tip is in proximity, i.e. after the tip
event on tip down and before the tip event on tip up.

We send the axis state in the proximity event so we don't send another axis
event for the same state. The first axis event is sent whenever the tool
moves. This is largely of note for test cases, in real-world usage a tool
cannot be held still enough to never send axis updates.

There were two files (doc/svg/{edge,twofinger}-scrolling.svg) that had both
arrow heads pointing to wrong direction. Those arrow heads used markers but
their ids were defined wrong and therefore they displayed weirdly. On Firefox
the arrow head that should have pointed to left pointed actually to right.
This commit fixes that problem by defining the marker ids correctly.
I tested on Firefox 40.0.3 that the arrow heads are now displayed correctly.

The Asus RoG Gladius exposes two event nodes, one mouse, one keyboard. The
keyboard node has REL_X/Y and REL_HWHEEL on top of the various key bits and
ABS_VOLUME.
The keyboard node does not have BTN_* set, udev tags this device as a
keyboard only, not as a pointer but we still initialize the pointer caps for
it because of the wheel.
When moving this mouse, some deltas (ca "1 in every 20") are sent through the
keyboard node, causing a crash because we never initialized pointer
acceleration.

The quartett of new config functions is:
libinput_device_config_accel_get_profiles
libinput_device_config_accel_get_profile
libinput_device_config_accel_set_profile
libinput_device_config_accel_get_default_profile
The profile defines how the pointer acceleration works, from a very high-level
perspective. Two profiles are on offer, "adaptive", the standard one we have
used so far and "flat" which is a simple multiplier of input deltas and
provides 1:1 mapping of device movement vs pointer movement.
The speed setting is on top of the profile, a speed of 0 (default) is the
equivalent to "no pointer acceleration". This is popular among gamers and
users of switchable-dpi mice.
The flat profile unnormalizes the deltas, i.e. you get what the device does
and any device below 800dpi will feel excruciatingly slow. The speed range
[-1, 1] maps into 0-200% of the speed. At 200%, a delta of 1 is translated
into a 2 pixel movement, anything higher makes it rather pointless.
The flat profile is currently available for all pointer devices but touchpads.

If a caller has a reference to a device group when the context is destroyed,
the memory for the group is never released. Calling
libinput_device_group_unref() will release it and there are no side-effects
since the group has no back-references. It's inconsistent with the rest of
libinput though - all other resources get released on libinput_unref().

The following sequence currently generates a right-button event:
finger 1 down
finger 2 down
finger 1 up
finger 2 held down
This is easily triggered with short scroll events. There are two issues here:
first is that the tapping code elsewhere treats any tap with a second finger
down as a left-button tap, not a right button one. So if anything, we should
generate a left button click here, not a right button click.
Arguably, generating a button click here is wrong though, it's not a very well
defined sequence and relatively difficult to trigger intentionally. So the
best solution here is to simply ignore the release event and move straight
back to state HOLD - unless the second finger is released within the timeout.
If the finger is set down again during the timeout, we move straight to
TOUCH_2_HOLD - this could eventually be interpreted as a tap, but not for now.

This is both a bug and required behavior. A caller may hold refcounted
references to devices, seats, or device groups but when libinput_unref()
cleans up, all these become invalid.
It is required behavior, because the last call to libinput_unref() also calls
libinput_suspend() and thus stops any events.
Any attempt at fixing this will break current behavior:
* keeping structs until all refcounts are 0 may leak memory in current
callers
* it would require an explicit call to libinput_suspend(), or make
libinput_unref() inconsistent in its behavior.
So we document it as a bug and tell people not to do it.
