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.

Give kernel image a header.
...
Kernel image now has a header with version, magic number, and a
pointer to its actual entrypoint. Entry point is now _start in
boot.s, and we now generate versions.s in the build tree for the
version macros.

Now the bootloader should be responsible for all initial setup,
loading the kernel, and then handing off to the kernel with
proper data in place.

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.
