[Fam Zheng]

Added support for zeroed-grain GTE to VMDK according to VMDK Spec 5.0[1].

[1] Virtual Disk Format 5.0 - VMware,
    http://www.vmware.com/support/developer/vddk/vmdk_50_technote.pdf?src=vmdk

Changes since v4:
 - 6/6: Correct endianess: *m_data->l2_cache_entry = offset;


Changes since v3:
 - 5/6: Remove tmp
 - 6/6: Update L2 Cache
        Remove redundant assignment to m_data
        Simplify l2_offset assignment to m_data
        Fix m_data.offset endian.

Changes since v2:
 - all: Added 5/6 (vmdk: store fields of VmdkMetaData in cpu endian)
 - 6/6: Avoid side-effect of vmdk_L2update.
        Change function comment to gtkdoc stype.

 - 1/5: squash one line of ret code macro change from 2/5
 - 2/5: change VMDK4_FLAG_ZG to VMDK4_FLAG_ZERO_GRAIN
 - 3/5: move BLOCK_OPT_ZEROED_GRAIN defination from block_int.h to vmdk.c
 - 5/5: fix metadata update issue, unit test with cases 033 034

Fam Zheng (6):
  vmdk: named return code.
  vmdk: add support for “zeroed‐grain” GTE
  vmdk: Add option to create zeroed-grain image
  vmdk: change magic number to macro
  vmdk: store fields of VmdkMetaData in cpu endian
  vmdk: add bdrv_co_write_zeroes
