Simon Ser 8681e4ab8a backend/drm, backend/libinput: listen to session destroy
This fixes a heap-use-after-free when the session is destroyed before
the backend during wl_display_destroy:

Greg V 9fe8e37961 Implement the pointer-gestures-unstable-v1 protocol
This protocol relays touchpad gesture events produced by libinput to
supporting clients (e.g. Evince, Eye of GNOME).

Ryan Walklin 2a3c62b4d2 [WIP][DONTMERGE]Add support for libinput_switch input devices
These are used primarily by laptops to signal
the state of the lid (open/closed) and tablet
mode if supported, based on ACPI events.

Markus Ongyerth d9e978e1b3 rename wlr_tablet_tool to wlr_tablet
The previous naming was based on the input-device capability names from
libinput.
With code that uses the libinput_tablet_tool and mapping into tablet-v2,
this is confusing, so the name is changed to follow the names used in
the protocol.

Markus Ongyerth 000b305ecc backend/libinput: Manage tablet tool livetimes
This adds the management code to manage tablet tools lifetimes from
libinput.
It follows the suggestion made in the tablet-unstable-v2.xml to destroy
tablet_tools once all tablets that it got into contact with were removed
from the system. This is implemented via a refcount.

If a tool is *not* unique, it will be destroyed on proximity out. This
is libinput specific and mentioned in libinput docs that tools will not
be found again, so we shouldn't keep a reference to them.
Also they can't be on other tablets as well, because they cannot be
tracked.

The naming in this commit is a bit off (to not break things).
The wlr names stay the same, tablet_tool is the libinput_device with
capaiblity LIBINPUT_DEVICE_CAP_TABLET_TOOL which is more akin to
"tablet" in the tablet-unstable-v2 protocol.
The struct that corresponds to the tablet_tool in tablet-unstable-v2 is
called tablet_tool_tool, a rename should be done at some point in the
future.
