action.

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

"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.

Cleanup and centralize the Makefile system even more.
Fix a gcc 4.3 incompatibility in memdisk (definition of strlen).

Compile with -std=gnu99, this allows us to define initializers inside
for() loops, which makes certain kinds of ugly macros easier to write.

Begin the process of centralizing configurables.

Improve "make install" and "make netinstall"; add "make
extbootinstall".

Move source files out of the root directory; the root is a mess and
has become virtually unmaintainable.  The Syslinux core now lives in
core/; the Linux and generic utilities has moved into utils/, and
copybs.com has moved into dos/; it had to go somewhere, and it seemed
as good a place as any.
