Subject[patch 1 of 4] Rename e820_map to e820_any_map to reflect its behavior better
From
Date
Rename e820_mapped to e820_any_mapped since it tests if any part
of the range is mapped according to the type. Later steps will introduce
e820_all_mapped which will check if the entire range is mapped with the type.
Both have their merit.
