block: initial VHDX driver support framework - supports open and probe

Enterprise / Virtualization / QEMU - Jeff Cody [redhat.com] - 3 May 2013 03:31 UTC

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=29681
