VMDK: move 'static' cid_update flag to bs field

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....

VMDK: change get_cluster_offset return type

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...

Add create option 'format', with enums:
monolithicSparse
monolithicFlat
twoGbMaxExtentSparse

VMDK: bugfix, align offset to cluster in get_whole_cluster

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: probe for monolithicFlat images

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...

VMDK: add field BDRVVmdkState.desc_offset

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....
