This lets us verify that all callers are actually testing for a successful hash lookup at compile time. All current users of hash_table_lookup are converted to the new wm_lookup_window() and the appropriate success check is added. This fixes any call sites that used to assume a successful return and dereference a NULL pointer. This closes http://bugs.freedesktop.org/show_bug.cgi?id=83994 The xwayland test has been failing because weston crashes due to a hash lookup failure and a subsequent dereference of the returned NULL pointer.

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.
