emul+cvm: link to curses instead of ncurses
NetBSD doesn't have ncurses. Linking to curses doesn't seem to change
anything. Tried on OpenBSD and Ubuntu.

emul: copy libz80 directly into tree, pre-generated
libz80 doesn't move much anymore, there not much advantage to the

Replace "-ansi" with "-std=c89" in emul/Makefile
"-ansi" is not supported by tcc, but according to gcc
documentation, "-std=c89" produces identical behavior.
See: https://gcc.gnu.org/onlinedocs/gcc-3.4.2/gcc/Standards.html

z80/8086: extract 2>R code from stable ABI zone
Only its jump at 0x33 remains.
I've also fixed a strange offset oddity in 8086's (n) placement.
It was off by 2, but strangely, it ran properly. Anyway, now it's
fixed.

Keep stage1 bootstrap bin instead of stage 0
XPACKed source needing to be kept in bootstrap bin didn't make
much sense. With the removal of stripfc, it makes more sense to keep
the compiled form of stage 1 in repository as a bootstrap binary.
Also, rename it to forth.bin.

emul: build boot binary in one pass
... instead of building boot.fs, and then z80c.fs/icore.fs in separate
passes. This strengten xcomp by making it support 2 completely separate
dicts (that is, the X dict is *not* connected to the system dict. The chain
now stops at EXIT def in boot.fs).

Replace bin2c.sh with a more portable implementation.
`xxd' is not available on all systems, and on others does not support
the `-i' flag. Since bin2c.sh relied on a tool that I can't seem to find
a compatible version of, I have included a simple, portable replacement in C.
Usage remains the same:
bin2c ARRAYNAME < inputfile > outputfile.
This change is also reflected in emul/Makefile.
