The qemu-iotests test suite requires filename parsing because it does
not use image options syntax everywhere. Add it now so that later
patches can enable qemu-iotests for the io_uring block driver.

The blkio.c code has other libblkio-based drivers that could benefit
from filename parsing too. Leave them for now because I am not yet ready
to add qemu-iotests support for them.
