Federico Simoncelli c6bb9ad198 qemu-img: find the image end offset during check
This patch adds the support for reporting the image end offset (in
bytes). This is particularly useful after a conversion (or a rebase)
where the destination is a block device in order to find the first
unused byte at the end of the image.

Stefan Hajnoczi 166f3c7b70 qemu-iotests: skip 039 with ./check -nocache
When the qemu-io --nocache option is used the 039 test case cannot abort
QEMU at a point where the image is dirty.  Skip the test case.

Stefan Hajnoczi dc68afe0f3 qemu-iotests: add 039 qcow2 lazy refcounts test
This tests establishes the basic post-conditions of the qcow2 lazy
refcounts features:

  1. If the image was closed normally, it is marked clean.

  2. If an allocating write was performed and the image was not closed
     normally, then it is marked dirty.

     a. Written data can be read back successfully.
     b. The image file can be repaired and will be marked clean again.
     c. The image file is automatically repaired when opened read/write.
