[PATCH weston 2/3] input: Provide microsecond timestamps in motion events

[Jonas Ådahl]

Provide timestamps with microsecond granularity if the backend can
provide it. Backends that can't should set it to 0.

This requires libinput master branch. I didn't add any dependency
checking since libinput hasn't been released with the new _get_time_usec
functions, but I doubt this will be merged before that so we can just fix
this patch after the next libinput version is released.
