This adds in read-only support to the VHDX image format. This supports reads for fixed-size, and dynamic sized VHDX images. Differencing files are still unsupported. The image must be opened without BDRV_O_RDWR set, because we do not yet update the headers. I.e., pass 'readonly=on' in the drive image options from the QEMU commandline.

This is the initial block driver framework for VHDX image support (i.e. Hyper-V image file formats), that supports opening VHDX files, and parsing the headers. This commit does not yet enable: - reading - writing - updating the header - differencing files (images with parents) - log replay / dirty logs (only clean images) This is based on Microsoft's VHDX specification: "VHDX Format Specification v0.95", published 4/12/2012 https://www.microsoft.com/en-us/download/details.aspx?id=29681Signed-off-by: NJeff Cody <jcody@redhat.com> Signed-off-by: NStefan Hajnoczi <stefanha@redhat.com>
