qemu-io: add "abort" command to simulate program crash
Avoiding data loss and corruption is the top requirement for image file formats. The qemu-io "abort" command makes it possible to simulate program crashes and does not give the image format a chance to cleanly shut down. This command is useful for data integrity test cases.
