1. Iterate over all partitions counted in the label, which can be more
than the number of partitions given to mkimg(1).
2. Start the checksum from the beginning of the label; not the beginning
of the bootarea.
Tested with bsdlabel(8).

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.

a raw image with a VHD footer appended. There's little value that I
can see to use the fixed image type, but in order to make VHD images
for use by Microsoft's Azure platform, they must be fixed VHD images.
Support has been added by refactoring the code to re-use common code
and by adding a second output format structure. To created fixed VHD
images, specify "vhdf" as the output format.
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.
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.

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.
sector granularity for both offset and length. Have all schemes
use mkimg_write() instead of mkimg_seek() followed by write(2).
Now that schemes don't use lseek(2) nor write(2) directly, it's
easier to support output formats other than raw disks.
