emul/hw/rc2014: implement blk write in sdc
All of that should help me implement sdc support much faster in
Forth.

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.

forth: remove dummy.fs
All "stop pings" are now explicitly made at appropriate places. This
fixes a problem I've introduced in the last commit where RAM+ was
unexpectedly part of a stable ABI because of "HERE" usage in dummy.fs.
This system will, anyways, soon change because boot.bin and z80c.bin
will be built during the same process (but there's a bit of retooling
to do before I get there).

forth: Remove RAM offsets from stable ABI
Doing this was a bit stupid. These offsets are constants. Moreover,
having them in stable ABI had us construct the boot binary from the
stable ABI of the host, making it very difficult to change RAMSTART
for a new system.

Forth self-bootstraps!!!
This commit cuts Forth's dependency on zasm. It now self-assembles
its own boot-binary! Things are a bit messy now, I'll clean up
later.

forth: simplify build process
Make LATEST configurable through a value in the binary instead of through
a ZASM constant. This enables the simple concatenation of compiled dicts and
simplifies the build process.
