For qemu-io, a function returns an integer with two possible values: 0
for "qemu-io may continue execution", or 1 for "qemu-io should exit".
However, there is only a single command that returns 1, and that is
"quit".
So let's turn this case into a global variable instead so we can make
better use of the return value in a later patch.
