This patch is just revert of [1]. Actually we should NOT pass
QEMU_ASYNC_JOB_NONE as that patch suggests while we are in async job in order
to acquire nested jobs correctly. The patch tries to fix issues introduced by
another patch [2] where jobs are mistakenly cleared out in qemuProcessStop.
Later patch [3] fixed the issue introduced by patch [2]. Now we need to revert
[1] as well as we now still have same concurrency crash issues as [3] described
but for the force revert.

We've dumped all the snapshot helpers and related code into
qemu_driver.c. It accounted for ~10% of overal size of qemu_driver.c.
Separate the code to qemu_snapshot.c/h.
