Merge remote-tracking branch 'stefanha/block' into staging
# By Fam Zheng (8) and others
# Via Stefan Hajnoczi
* stefanha/block:
qemu-iotests: Filter out 'adapter_type'
nbd: support large NBD requests
nbd: use g_slice_new() instead of a freelist
qemu-iotests: Filter out vmdk creation options
vmdk: add bdrv_co_write_zeroes
vmdk: store fields of VmdkMetaData in cpu endian
vmdk: change magic number to macro
vmdk: Add option to create zeroed-grain image
vmdk: add support for “zeroed‐grain” GTE
vmdk: named return code.
blockdev: Replace "undefined error" in qmp_block_resize
block: add read-only support to VHDX image format.
block: initial VHDX driver support framework - supports open and probe
block: vhdx header for the QEMU support of VHDX images
qemu: add castagnoli crc32c checksum algorithm
