Some Linux distributions have complained about Perl as a prerequisite
for isohybrid, so create a C version.

[ hpa: modified the array generator to put it all in one script ]

Replace -W -Wall hardcoded into a bunch of Makefiles with $(GCCWARN),
a centralized variable defined in the root MCONFIG.  Add
-Wstrict-prototypes to the list of global warnings: we should never
have non-prototyped declarations.

Fix CBIOS in isohybrid mode.  Also allow an isohybrid image to be
booted from a partition.  Unfortunately this breaks compatibility
between differing versions of isohybrid and isolinux.bin.

Allow selecting the _f or _c versions of the prefix in addition to the
default one.  This is specified with the -forcehd0 or -ctrlhd0
options.

Make the dependency generation more common; have a general pattern in
MCONFIG, and use it in rules (not in CFLAGS).

For NASM source, in order to stay compatible with old versions of
NASM, run NASM twice; newer versions of NASM is capable of generating
dependencies simultaneously like gcc can, but that would break
compatibility with older distros.

Begin the process of centralizing configurables.

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