qemu-io: add "abort" command to simulate program crash

Browse Source 
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.
