cmd_image_create
Add a tool for creating small image files.
Data is written out in a reproducible order, sequentially from the
start of the device.
Metadata is initially written to a temporary device, then after writing
out data, the metadata we want to keep (alloc info is left out by
default) is migrated to the real device.
Then, the image file is trimmed to minimum size and the temporary
metadata device dropped.
