Changes from v1:
2/6: add vmdk_free_last_extent, fix qemu_realloc bugs, shorten vmdk_open,
remove unused comment
4/6: fix endianess bug
5/6: simplify qemu_free call, change qemu_mallocz to qemu_malloc, fix
endianess bug
Fam Zheng (6):
VMDK: enable twoGbMaxExtentFlat
VMDK: add
Factor out read/write extent code, since there will be more things to
take care of once reading/writing compressed clusters is introduced.

The vSphere 4 exported image is streamOptimized extent, which is not
quite correctly handled. Ignore rdgOffset when RGD flag bit not set.

Haiku provides a specially formed vmdk image, which let qemu abort. It a
combination of sparse header and flat data (i.e. with not l1/l2 table at
all). The fix is turn to descriptor when sparse header is zero in field
'capacity'.
