Propagate attribute overrides up to the HBRT code

Attribute overrides are stored in a separate tank of memory from
the regular attribute values.  This tank will be added as an
additional reserved memory section for HBRT to consume (only if
overrides exist).

Also fixed a couple bugs encountered while testing:
- No longer crashes if an error is created inside the targeting
  initialization code.
- Added reserved bytes to RHB definition.
