Create a new function weston_compositor_read_presentation_clock() to wrap the clock_gettime() call for the Presentation clock. Reading the presentation clock is never supposed to fail, but if it does, this will notify about it. I have not seen it fail yet, though. This prepares for new testing features in the future that might allow controlling the presentation clock. Right now it is just a convenience function for clock_gettime(). All presentation clock readers are converted to call this new function except rpi-backend's rpi_flippipe_update_complete(), because it gets its clock id via a thread-safe mechanism. There shouldn't be anything really thread-unsafe in weston_compositor_read_presentation_clock() at the moment, but might be in the future, and weston core is not expected to need to be thread-safe.

Weston Weston is the reference implementation of a Wayland compositor, and a useful compositor in its own right. Weston has various backends that lets it run on Linux kernel modesetting and evdev input as well as under X11. Weston ships with a few example clients, from simple clients that demonstrate certain aspects of the protocol to more complete clients and a simplistic toolkit. There is also a quite capable terminal emulator (weston-terminal) and an toy/example desktop shell. Finally, weston also provides integration with the Xorg server and can pull X clients into the Wayland desktop and act as a X window manager. Refer to http://wayland.freedesktop.org/building.html for building weston and its dependencies. The test suite can be invoked via `make check`; see http://wayland.freedesktop.org/testing.html for additional details.
