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,

VMDK: bugfix, align offset to cluster in get_whole_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
