Remove disk image support from ISOLINUX.  Very few BIOSes support this
call correctly, and it is likely to have been broken for a very long
time anyway.

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

Move sector 1 to 0x8000, so that it will be sector-aligned no matter
what the sector size is (well, as long as it is <= 32K).  This avoids
potential conflicts between the 64K "seams" and the sector size.
