CBMEM high table memory manager.

Browse Source 
This code adds a very simple toc based memory manager for the high tables area.
The purpose of this code is to make it simpler and more reliable to find
certain data structures in memory. This will also make it possible to have ACPI
S3 Resume working without an ugly hole at 31MB.
