Move uninitialised .data16 variables to .bss16; saves around 2000
bytes of useless zeroes in the final image.

Make the getmemsize() prototype available in memsizes.h, for code that
doesn't want to go to the hassle of processing a full memory map.

Move memmap.h out of arch/i386; it no longer contains anything
architecture-dependent and is needed by the ELF code.

We don't actually have a stdio.h header file. Our printf() functions are
defined in vsprintf.h. (This may change, since vsprintf.h is a
non-standard name, but for now it's the one to use.)
There should be no need to include vsprintf.h just for DBG() statements,
since include/compiler.h forces it in for a debug build anyway.

Define a struct memory_map with a fixed number of entries, rather than
requiring each caller to decide how many entries it wants to permit.

Set carry flag before calling INT 15,e801 and INT 15,e820.
Ignore carry flag for INT 15,88; the Ralf Brown interrupt list says
that CF is unreliable for this call.

Replaced memsizes.c with smaller memmap.c, taking advantage of __data16,
and creating a memory map that's easier to work with than the E820 map.
