WM_TAKE_FOCUS requires a valid timestamp that isn't XCB_TIME_CURRENT. To
get one, we set a property on the window and wait for the notification
that it was set - this notification comes with a valid timestamp.
Once we have that timestamp, delete the property, and fire off the slightly
delayed WM_TAKE_FOCUS client request.

https://specifications.freedesktop.org/wm-spec/1.4/ar01s05.html says
"The Window Manager MUST set _NET_FRAME_EXTENTS to the extents of the
window's frame", so this is probably something we should be doing.
Some programs (such as some versions of Firefox) expect this to be present,
and will render popups in wrong locations if it's not.

Avoid duplication of atom retrieval. This is particuarly useful
if one would one to reuse atom retrival in other parts, like tests.
