[PATCH v4 02/11] test_driver: Introduce testIOThreadInfo and generate IOThread infos
Introduce testIOThreadInfo to store IOThread infos: iothread_id,
poll_max_ns, poll_grow and poll_shrink for future usage.
Add an example of IOThread configuration to testdomfc4.xml, we also want
to generate default testIOThreadInfo for the IOThread configured in the
xml, so introduce testDomainGenerateIOThreadInfos, the values are taken
from QEMU.
