Allowing the user to specify what mode we use to open a file is IMHO not 
a good interface for a user.  A user should only be concerned with how 
we expose a disk to the guest, not the underlying implementation of how 
we support this.  It has subtle side-effects that a user is not going to 
expect unless they are intimately familiar with how QEMU is implemented 
(like snapshotting breaking).
