Amit Mendapara c66a974f1d [client] wayland: marshal resize requests to the event-loop thread ...

setWindowSize is called from the render, frame and transport threads,
but shellResize issues shell requests and, with the libdecor GTK
plugin, renders the window decorations through pango, none of which is
thread safe. A frame thread exiting after such a call crashed in the
pango fontmap destructor during thread teardown.

Publish the requested size atomically and wake the event loop through
an eventfd registered in the epoll; the poll callback applies the size
on the event-loop thread. Concurrent requests coalesce into the most
recent one.
