30bd6a4daf iotests: Test new blkdebug/blkverify interface
Add a test for the new blkdebug/blkverify interface.

This test is not written in Python, although it uses QMP. This is
because it invokes the qemu-io HMP command, which outputs errors to
stderr instead of returning them through QMP. Filtering and testing that
output is easier in a shell script than with the Python infrastructure.

9c468a013f qemu-iotests: add 058 internal snapshot export with qemu-nbd case
This case can't run when IMGPROTO=nbd, since it needs to create some
internal snapshot which would fail for EOF write request, even when
TEST_IMG is exported with "-f raw" in common.rc, so set _supported_proto
to file.

_require_command() is changed to tip what util is missing, instead
of printing a blank.

e78835b722 block: vhdx qemu-iotest - log replay of data sector
This tests the replay of a data sector in a VHDX image file.

The image file is a 10G dynamic image, with 4MB block size.  The
image was created with qemu-img, and the log left unplayed by
modification of the vhdx image format driver.

It was verified under both QEMU and Hyper-V that the image file,
post log replay, matched.

89e911816a block: qemu-iotests for vhdx, read sample dynamic image
This adds the VHDX format to the qemu-iotests format, and adds
a read test.  The test reads from an existing sample image, that
was created with Hyper-V under Windwos Server 2012.

The image file is a 1GB dynamic image, with 32MB blocks.

The pattern 0xa5 exists from 0MB-33MB (past a block size boundary)

The pattern 0x96 exists from 33MB-66MB (past another block boundary,
and leaving a partial blank block)

From 66MB-1024MB, all reads should return 0.

Although 1GB dynamic image with 66MB of data, the bzip2'ed image
file size is only 874 bytes.

This also adds in the IMGFMT_GENERIC flag, so r/o images can be
tested (e.g. ./check -vhdx) without failing tests that assume
r/w support.
