History
John Griffith c42273fbc1 Make sure device support Direct before setting 
We added '-t none' option to the qemu-img convert operation
in image_utils.py a while back to accomodate a couple of
backend devices that didn't flush writes on disconnect.
(Change: I7a04f683add8c23b9125fe837c4048ccc3ac224d)

The only problem here is that some backend devices don't
support Direct mode and raise an exception and fail when
setting this option.

This patch adds a simple check using dd to see if the dest
supports the Direct flag and only sets '-t none' if the device
does in fact support it.

Additionally it was brought up that even yet other backends
are using file devices not blk devices.  In their case setting
Direct will still work, however it's sub-optimal as qemu-convert
has internal mechanisms to make sure flushing etc are done
correctly and efficiently for those devices.  So to accomodate
that particular use case I'm also adding a check if blk dev
that can be used for determining whether to set Direct for the
qemu-convert process.
