This patch marks QED images as clean periodically when it is safe to do so.
This reduces the chance of having to perform a consistency check at startup.
Previously we left the image dirty even when it was consistent, therefore
risking an unnecessary consistency check after crash.

The first patch stubs out qemu-timer.c functions for qemu-tool.c, which is
needed since block drivers get built into qemu-img and friends.  In the long
run having timers in qemu-tool too would be good, but for now they are not
critical and the stub implementation works.
