[Qemu-devel] [PULL v3 18/38] iotests: Filter out "I/O thread spun..." warning

[Stefan Hajnoczi <stefanha@redhat.com>]

From: Max Reitz <mreitz@redhat.com>

Filter out the "main loop: WARNING: I/O thread spun for..." warning from
qemu output (it hardly matters for code specifically testing I/O).

Furthermore, use _filter_qemu in all the custom functions which run
qemu.
