- Use the headers from ACPI-CA to define various constants and structures

Browse Source 
for table layouts, etc. rather than homerolling our own structures and
  constants in acpidump.h.
- Verify the extended checksum on the RSDP.
- Handle new ACPI 3.0 fields in MADT including X2APIC entries and
  UIDs for local SAPICs.
- Add handling for new ACPI 3.0 flags in the FADT.
