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.

2af959a13d Don't use IMMEDIATE in icore 
Since the fix of its RAM addr, we use the wrong CURRENT in every
usage of IMMEDIATE in icore. We therefore have to manually set the
flag for all 3 immediate words in that unit.

80891d7ec1 Add in-memory bootstrapping system 
This should help with the bootstrapping of non-emulated environment.
For example, I have a problem with the RC2014: I can't send it
bootstrap info until the ACIA is up. I need to find a way...

2481ed4b66 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).

68a7be3707 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.

d0c5d3a741 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.

e846d07238 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.
