[PATCH weston 0/6] libweston: Support input_timestamps_unstable_v1

[Alexandros Frantzis]

The input_timestamps_unstable_v1 protocol allows clients to subscribe to
high-resolution timestamp events for input events (see [1]).

This patchset implements the input_timestamps_unstable_v1 protocol in libweston
and also adds tests for the implementation in the weston test suite. Note that,
as expected, this patchset depends on the presence of the protocol description
file, which is currently pending inclusion in wayland-protocols.

Patches (1) and (2) introduce some helper code which is used by later patches.
Patch (2) in particular adds test helpers that also act as a nice example of a
client side implementation of the input_timestamps_unstable_v1 protocol.

Patch (3) introduces some common support code in libweston, which allows for
cleaner and more focused patches for keyboard, pointer and touch timestamp
event support in patches (4), (5) and (6) respectively.
