Update the sandbox implementation to use UCLASS_HOST and adjust all the pieces to continue to work: - Update the 'host' command to use the new API - Replace various uses of UCLASS_ROOT with UCLASS_HOST - Disable test_eficonfig since it doesn't work (this should have a unit test to allow this to be debugged) - Update the blk test to use the new API - Drop the old header file Unfortunately it does not seem to be possible to split this change up further.
