Move the MCONFIG files into a mk/ directory and give them more
descriptive names.

This is purely a cosmetic change to make the 'include' directives a
bit more coherent by making it obvious exactly which MCONFIG file
we're including. For example, in com32/lua/src/Makefile we exchange
the line,

	include ../../MCONFIG

for the much more comprehensible,

	include $(MAKEDIR)/com32.mk

At least until we can get a better handle on return vs INT 18h,
provide a module so we can at least tell people how to test.

This module is able to power off a system via APM.
It was tested on QEMU, Bochs and VMware.

Possible usage:

TIMEOUT 3000
TOTALTIMEOUT 9000
ONTIMEOUT poweroff.com

Align I/O buffers to a multiple of 512 bytes, as required by the
Syslinux ABI.  Furthermore, move them from data to bss, so that they
don't occupy space in the image file.

Fix missing -M from NASM dependency generation calls; adopt the
uniform stanza "-M -DDEPEND" even for sites that were already correct.

Also, use ">" not ">>" for obvious reasons...

Unify dependency generation and move common rules into
MCONFIG.embedded.

A COMBOOT module to interface to Steffen Winterfeldt's Gfxboot
graphical front end (http://gfxboot.sourceforge.net/).

"make clean" must NOT remove stuff that "make installer" should not
rebuild.  This is a somewhat unfortunate choice of naming, but that's
the way it is.
