v6: Less resource demanding patch 5. (Max)
Add rev-by of Max to other patches.
v5: Rebase and improve the test. Please review again.
Patch dependencies:
This test depends on the qtest timer fix to run correctly.

Also depends on the os check fix to run at all:

Original cover letter
---------------------
There is a change in qemu-io sub-commands "aio_read" and "aio_write", which
makes the aio requests accounted and the statistics reflected in blockstats.
Note that IO throttling implementation allows overcommiting of requests, so the
actual IO happened in a time unit may be a bit larger than given limits. In the
test case, the stats numbers are compared with a 10% error tolerance, to make
room for such flexibility in order to improve determinism.

Fam Zheng (5):
qemu-io: Account IO by aio_read and aio_write
qtest: Add scripts/qtest.py
qemu-iotests: Add VM method qtest() to iotests.py
qemu-iotests: Allow caller to disable underscore convertion for qmp
qemu-iotests: Add 093 for IO throttling
