tests/qemu-iotests: add QEMU_IOTESTS_REGEN=1 to update reference file
When developing an I/O test it is typical to add some logic to the test script, run it to view the output diff, and then apply the output diff to the reference file. This can be drastically simplified by letting the test runner update the reference file in place. By setting 'QEMU_IOTESTS_REGEN=1', the test runner will report the failure and show the diff, but at the same time update the reference file. So next time the I/O test is run it will succeed. Continuing to display the diff when updating the reference gives the developer a chance to review what was changed. Reviewed-by: Eric Blake <eblake@redhat.com> Signed-off-by: Daniel P.
