For conditional touchpad disabling we need two pieces of knowledge: is the
device an internal touchpad and is another device an external mouse-like
device. For that use-case it's enough to tag any device that's on USB and
Bluetooth with pointer capabilities as external mouse. A more complex can be
done when needed.
The tag function is part of the dispatch interface (to save on udev code) and
called before the caller is notified about the new device, i.e. the device is
fully configured by the time it needs to be tagged, and other devices can rely
on the tags being assigned by the time they get notified about the new device.

When a device is added or removed, notify all internal devices about the
device change. This allows all devices to configure themselves depending on
other devices in the system. Prime use-case here is an internal touchpad that
wants to know if an external mouse is connected.
On device added, notification goes both ways: existing devices are notified
about the new device, and the new device is notified about existing devices.
On device removed, notification only goes one way.
In both cases, the internal notification is complete before the event is sent
to the caller.

We previously called this function only before device removal, so failing to
update the button state didn't matter. To make this function generic for the
device suspend/resume, we need to keep track of the button/key count properly.
If we have a key down multiple times on suspend though, log a bug.
The dispatch should release the keys before we even get here (functionality
added in a subsequent patch).

A device may disappear and a new device may re-appear with the same device
node while the original device is suspended. Prevent a device resume to open
the wrong device.
In a path context, a changing syspath is the only indicator we get of the
device changing.
In a udev context, if the device was removed and libinput_dispatch() was
called, we can short-cut the syspath comparison by setting it to NULL.

The evdev fallback dispatch supports enabling and disabling devices. That's
fairly easy to support since we don't (yet) have extra event generation within
the fallback backend. Thus, we can simply close the fd and re-open it again
later.
Touchpads are currently excluded here, they generate extra events on tapping,
scrolling, and software buttons and need a more complex implementation.

Rather than adding a config interface to disable a device merely allow a
caller to toggle the "send events" mode on the device. If off, the device
won't send events (though further events may be received depending on the
current state of the device).
Default is enabled, i.e. the device sends events.
A special mode is added to the obvious enable/disable: disable the device when
an external mouse is connected. Once set, the device will be enabled when no
mouse is present and stop sending events otherwise. This isn't hooked up to
anything yet though.
Built into the config API is the default option of "enabled". Any device
supports this, for the obvious reason. Disabling or conditionally disabling is
left to the implementation.

It should be possible to initiate a drag by tapping-drag, but continue
it by pressing a physical button continuing to drag by subsequent finger
motions.
As the generic evdev layer helps us ignore multiple button presses we
can have the tap machine run completely separate from and uneffected by
regular physical button presses, making the tap FSM much simpler than
adding new states for handling button presse life times from outside
of the tap state machine.
A touchpad test is updated to test click while tapping instead of tap
FSM break out. The updated test is re-added but only for clickpads only.
The tap FSM svg is updated to say "clickpad button press" instead of
"phys button press".

The big change here is the requirement to have the translation component in a
device-normalized coordinate space. Without that, we cannot reliably rotate as
the coordinate space is effectively unknown and may differ between the axes.
This affects any rotation matrix or translation matrix, pure scale matrices
were working just fine since they're unit-less.
Requiring the matrix in device-normalized space makes it possible for libinput
to rotate or otherwise handle the matrix independent of the screen resolution.
The rotation matrix is documented in a bit more detail to make it easier for
users to figure it out.
This changes the definition of the WL_CALIBRATION property (which is currently
broken).

In the current code the caller can't know if the fd was closed on error since

latter case the fd was closed, not in the former. The caller had to close
