e->code is in the same range for ABS_ and for REL_. As the code currently
stands and for the current values in Linux's input.h there is no risk of a
problem. However just in case it would be wise to break after evaluating the
relative events.

As said by krh: "Maybe we should also just call it an evdev_device
instead, shorter [and] not really ambiguous."
[krh: if my typo filled irc is going in a commit message, I'm at least going
to insert the missing words.]

evdev_led_update() does not really need the whole list of device at
once, it can be called one device at a time.

evdev.c: In function 'evdev_led_update':

Useless in this case.

Weston's notify_keyboard_focus_*() assume that a keyboard is present, if
they are called. With evdev, there might not always be a keyboard.
Also clean up the variable definition in evdev_notify_keyborad_focus().
I read that function through many times and finally had to grep where
does 'all_keys' come from.

Move all udev-related and now drm backend specific code into
compositor-drm.c.
This makes evdev.c free of udev and launcher-util, and allows it to be
used on Android.

This makes the generic evdev code (i.e. the functions not relying on
udev) independent of launcher-util too. The aim is to allow re-using the
generic evdev code in the Android backend, where neither udev nor
launcher-util are available.
evdev_input_device_create() signature is changed:
- add the opened device file descriptor
- remove wl_display as unused
Also add a bit of failure logging.

evdev_input_device_destroy() will completement the API of
evdev_input_device_create(), both being independent from udev.
Since the udev-specific device_removed() would only call
evdev_input_device_destroy() and do nothing else, device_remove() calls
are simply replaced with evdev_input_device_destroy().

For a true multi-touch input device, the code ended up using
uninitialised fields of evdev_input_device::abs.
Fix it by querying the corresponding MT ranges.

Most touchscreen drivers provide ABS_X and BTN_TOUCH for legacy
single-touch emulation modes, but this isn't mandatory. Make sure we
don't ignore touchscreens with provide multitouch events with the new
API only.

If update_state is true, then notify_key will continue to call
xkb_key_update_state to update the local state mask, as before this
commit. Otherwise, it will rely on the compositor to manually update
the state itself, for nested compositors.

The O_RDWR change got lost in a rebase, and as Peter suggested as well,
make sure to set EVDEV_KEYBOARD if the device has EV_LED.

This allows backends to generate their own keymaps and pass them in for
use rather than always forcing a single global keymap, which is
particularly useful for nested compositors.

Instead of using a uint32_t for state everywhere (except on the wire,
where that's still the call signature), use the new
wl_keyboard_key_state enum, and explicit comparisons.

Touchpad related code has been rewritten and moved to its own file
accessed by evdev via the dispatch interface.
The various functionality implemented are anti-jitter (don't jumping
around), smoother motions, touch detection, pointer acceleration and
some more.
Pointer acceleration is implemented as one generic part, and one touch
specific part (a profile).
Some ideas and magic numbers comes from xserver and
xf86-input-synaptics.

By setting an 'evdev_dispatch' struct in 'evdev_input_device' during
device configuration the 'process' function in the associated interface
will be called with received input events. If none is set, a fallback
handler will be set instead that handle generic input functionality.

wl_input_device has been both renamed and split. wl_seat is now a
virtual object representing a group of logically related input devices
with related focus.
It now only generates one event: to let clients know that it has new
capabilities. It takes requests which hand back objects for the
wl_pointer, wl_keyboard and wl_touch interfaces it exposes which all
provide the old input interface, just under different names.
This commit tracks these changes in weston and the clients, as well as
similar renames (e.g. weston_input_device -> weston_seat). Some other
changes were necessary, e.g. renaming the name for the visible mouse
sprite from 'pointer' to 'cursor' so as to not conflict.
For simplicity, every seat is always exposed with all three interfaces,
although this will change as time goes on.

We dont want to receive hotplug events while being inactive.
When getting back active we enumerate all devices and would end up
with two sources for one device that may be hotplugged in the mean time.
weston-launch starts weston and provides mechanism
for weston to set/drop drm master, open a tty,
and read input devices without being root.
Execution is allowed for local-active sessions
or users in the group weston-launch.
Just like device_added, now the routines to close the compositor and vt switch
leave are using the same code to remove a device.
This patch also closes properly a mtdev device, bug spotted by Christopher
Michael.

When the compositor is in a repaint cycle, input is processed only once
per frame. However, a call to evdev_input_device_data() would handle at
most 8 events at time. When there was more than 8 events pending for a
given frame, input lag would occur. This was most visible with multi
touch input.
This patch changes the evdev_input_device_data() so that it will handle
all the events available in the fd. In order to do that, the fd is put
in non-blocking mode, so that it is possible to loop on read and stop
on EAGAIN instead of blocking.
mtdev library translates all multitouch based devices to the slotted evdev
protocol. It provides an uniform interface for Weston, which eases mt
implementation when dealing with a big variety of devices.
Weston on drm now directly depends on such library.
