Truly enable virtual memory.
...
Map is still identity-mapped. I think we need to sort and/or clean up
the map before using a higher half address. In-kernel vga output not
working yet, but do_the_set_registers() is getting called.

Added memory.c
...
Includes routine replacing efilib's LibMemoryMap, and a debug function for
dumping the map to the console. Currently get_memory_map() is only used
for the debug function dump_memory_map.
Thanks to Finnbar Murphy for the blog post that helped me figure out why
my memory map iteration was wrong.
