For image formats that are not "QEMU native", but supported for
compatibility, it is useful to verify that an image created with
the 'gold standard' native tool can be read / written to successfully
by QEMU.
In addition to testing non-native images, this could also be useful to
test against image files created by older versions of QEMU.
This provides a directory to store small sample images, for use by
scripts in tests/qemu-iotests.
Image files should be compressed with bzip2.
To use a sample image from a bash script, the _use_sample_img function
will copy and decompress the image into $TEST_DIR, and set $TEST_IMG to
be the decompressed sample image copy. To cleanup, call
_cleanup_test_img as normal.
