indentations / style (Kevin)
Removed/fixed outdated comments (Stefan)
dropped vhdx_header_padded (Kevin)
Patch 3/4: removed hunk that was meant for old patch 5/5 (Fam)

Patch 5 (v2): Dropped
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
Jeff Cody (4):
qemu: add castagnoli crc32c checksum algorithm
block: vhdx header for the QEMU support of VHDX images
block: initial VHDX driver support framework - supports open and probe
block: add read-only support to VHDX image format.
