Probe as the same behavior as VMware does.
Recognize image as monolithicFlat descriptor file when the file is text
and the first effective line (not '#' leaded comment or space line) is
either 'version=1' or 'version=2'. No space or upper case charactors
accepted.

There are several occurrence of magic number 0x200 as the descriptor
offset within mono sparse image file. This is not the case for images
with separate descriptor file. So a field is added to BDRVVmdkState to
hold the correct value.

Add create option 'format', with enums:
monolithicSparse
monolithicFlat
twoGbMaxExtentSparse
twoGbMaxExtentFlat
Each creates a subformat image file. The default is monolithiSparse.

qemu-img.c wants to count allocated file size of image. Previously it
counts a single bs->file by 'stat' or Window API. As VMDK introduces
multiple file support, the operation becomes format specific with
platform specific meanwhile.
The functions are moved to block/raw-{posix,wi

Cid_update is the flag for updating CID on first write after opening the
image. This should be per image open rather than per program life cycle,
so change it from static var of vmdk_write to a field in BDRVVmdkState.

The return type of get_cluster_offset was an offset that use 0 to denote
'not allocated', this will be no longer true for flat extents, as we see
flat extent file as a single huge cluster whose offset is 0 and length
is the whole file length.
So now we use int return value, 0 mean

In get_whole_cluster, the offset is not aligned to cluster when reading
from backing_hd. When the first write to child is not at the cluster
boundary, wrong address data from parent is copied to child.

VMDK multiple file images can not be recognized for now. This patch series is
adding monolithic flat support to it, that is the image type with two
files, one text descriptor file and a plain data file. This type of
image can be created in VMWare, with the options "allocate all di
