lib: add memrange infrastructure
The memrange infrastructure allows for keeping track of the machine's physical address space. Each memory_range entry in a memory_ranges structure can be tagged with an arbitrary value. It supports merging and deleting ranges as well as filling in holes in the address space with a particular tag. The memrange infrastructure will serve as a shared implementation for address tracking by the MTRR and coreboot mem table code.
