RFC/pull: evdev input for android, and touch fixes

[Pekka Paalanen]

Hi Kristian,

I will be replying to this email with a patch series for Wayland and
Weston, that will make evdev input devices work on Android.

It splits udev and weston-launcher related code out from evdev.c, so I
can reuse evdev.c on Android. That is the bulk of the work. There are
various bug fixes, especially for touch devices, which apparently have
not been tested after the wl_seat conversion. Found input devices are
printed to the log, for both drm and android backends.

In the end, on a Galaxy Nexus device, I have the three buttons working
as a keyboard, and the touchscreen as a touch device, which simple-touch
confirms to be working.

I have also tested the DRM backend on my laptop, with
hotplugging/removing a mouse, to check that I did not break anything.

The Wayland patches are only as email, but the Weston series can also
be found in a branch:

The following changes since commit 1248158e7d9a14cbed14b47c83bf83d4ca61ec91:

Finally, a question:

It seems structs wl_pointer, wl_keyboard, and wl_touch have a
destroy listener only for focus_resource, but not for the focus
(surface). Should the other listener be added, or is it handled by some
unobvious way? What about making a 'struct focus' for containing all
the common focus-related fields in the three structs, with common
callback functions for listeners?


Thanks,
