[RFCv2 00/38] Hyperlaunch domain builder

["Daniel P. Smith" <dpsmith@xxxxxxxxxxxxxxxxxxxx>]

NOTE: Sending this series as an RFC as it is a follow-on to the hyperlaunch
dom0 device tree series going through rounds of review right now. This
iteration of the RFC series is based off of v6 of the dom0 device tree series.

The Hyperlaunch domain builder series is the third split out for the
introduction of the Hyperlaunch domain builder logic. These changes focus on
introducing the ability to create multiple PVH domains at boot. The definition
for those domains will come from the Device Tree capability introduced in the
dom0 device tree series.

Significant Changes in v2:
- bzimage renetrant was dropped for a proper refactoring of kernel headroom and
  expansion
- While there is concern on the affect for pv construction, event channel
  allocation has been delayed to a newly introduced builder_finalize function
  called after all construction has completed
