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.

This is for small sample images to be used with qemu-iotests, intended for non-native formats that QEMU supports for compatibility. The idea is to use the native tool to create the sample image. For instance, a VHDX image in this directory would be an image created not by QEMU itself, but rather created by Hyper-V. Sample images added here must be compressed with bzip2.
