test: verify that a vhd can be streamed as a self-contained vhd
test: verify that a vhd can be streamed as a self-contained vhd

For every interesting vhd bit pattern we use the streaming API
to write out a consolidated, self-contained vhd. We then open
this and check the contents are the same, modulo allowing for
all sectors to be present in the sector bitmap.

This test currently fails.
