When booting Chrome OS images the command line is stored separately
from the kernel. Add a way to specify this address so that images boot
correctly.

Also add comments to the zimage.h header.

There is a lot of information in the setup block and it is quite hard to
decode manually. Add a 'zboot dump' command to decode it into a
human-readable format.

At present the setup block is always obtained from the image
automatically. In some cases it can be useful to use a setup block
obtained elsewhere, e.g. if the image has already been unpacked. Add an
argument to support this and update the logic to use it if provided.

At present the 'zboot' command does everything in one go. It would be
better if it supported sub-commands like bootm, so it is possible to
examine what will be booted before actually booting it.

In preparation for this, move the 'state' of the command into a struct.
This will allow it to be shared among multiple functions in this file.
