The purpose of this release is primarily to update the copyright years
in each module, thus causing a huge number of diffs.  There are a few
small functional changes, however.

Improved error messages when there is a problem finding one or more of
the required base ACPI tables

Reintroduced the definition of APIC_HEADER in actbl.h

Changed definition of MADT_ADDRESS_OVERRIDE to 64 bits (actbl.h)

Removed extraneous reference to NewObj in dsmthdat.c
