A struct boot_domain now encapsulates the domain reference, kernel, ramdisk,
and command line for the domain being constructed. As a result of this
encapsulation, construct_dom0 can now take a single struct boot_domain instead
of these four parameters.

Changes since v5:
- moved back to using variable *d to hold domain reference locally
