6219349311 Create a redundant grain directory and table. Previously we were
cheating by assigning the same sector offset to both directories,
but it seems that VirtualBox doesn't like that. Neither does
qemu from the looks of it.  We now actually write the directory
and table twice.

a0f136e1c5 Add image_data() for checking whether a sequence of blocks has data.
Use this for VHD and VMDK to avoid allocating space in the image
for empty sectors.

Note that this negatively affects performance because mkimg uses a
temporary file for the intermediate storage. When mkimg has better
internal book keeping, performance can be significantly improved.

f3582a728d Add VHD support to mkimg(1). VHD is used by Xen and Microsoft's Hyper-V
among others.

Add an undocumented option for unit testing (-y). When given, the image
will have UUIDs and timestamps synthesized in a way that gives identical
results across runs. As such, UUIDs stop being unique, globally or
otherwise.

VHD support requested by: gjb@

f0e9dced5c MFuser/marcel/mkimg:
Add support for different output formats:
1.  The output file that was previously written is now called the raw format.
2.  Add the vmdk output format to create VMDK images.

When the format is not given, the raw output format is assumed.
