This adds the initial support for VHDX image files.
It currently only supports read operations of VHDX, for fixed and dynamic files.
Notably, the following is not yet supported:
* Differencing files
* Log replay (so we will refuse to open any images that are not 'clean')
* .bdrv_create()
* write operations other than to the header
