[PATCH weston v2 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.

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.

Patches (3) to (6) implement the protocol in libweston.

v2 of this patchset has been rebased on the recent libweston changes to improve
handling of inert input resources, and is thus able to provide similar robust
handling of inert resources for the input_timestamps_unstable_v1 objects.  See
each patch for more detailed changes in v2.
