d08a9711c5 boot: make HERE point to RAMEND instead of CURRENT 
The former was only used in the peculiar context of "/emul". The
regular case is actually HERE pointing to RAMEND on boot.

d996dd8c9e Add one layer of indirection in subsystem memory management 
This allows optional subsystems to not needlessly reserve too much
system memory and it also reduces offsets bookkeeping.

c515720e23 Revert "Remove link.fs" 
Let's revisit the relinking approach, with LITA this time.

3822182226 xcomp: shrink scope 
It seems that xcomp can't manage to reliably compile core+ units.
Let's limit the role of xcomp to z80c+icore.

I'm getting a little desperate here. I'll revisit the link.fs approach
with a new idea I had...

6368cc3bac Remove (sysv) 
Replace its usages with direct RAM+ offsets. The (sysv) mechanism was
incompatible with cross-compilation of a full interpreter.

7aa1be070b 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.

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.

48078d9c9c forth: Replace "SKIP?" with "(?br)" 
There is an alternate git history where I continued the Forth-ification of
words, including "SKIP?", but that was a bad idea: because that word was
written by flow control immediates, I stepped into quicksands where stability
became necessary in z80c.fs and I couldn't gracefully get out of it.

I'm stepping back and take this opportunity to replace the shoddy SKIP? algo
with a more straightforward (?br) implementation.

(br) and (?br) will always stay in boot code where it's easier manage a stable
ABI.

549cf74e9d forth: inline code from "apps/lib" 
Forth-ification of Collapse OS goes forward. What will happen is that assembly
code in apps/ will become Forth code. The concept of an assembler code library
will become obsolete.

However, Forth's core use some of that code. To facilitate the transition, I'm
inlining that code directly in Forth's code.

c3838714d5 forth: improve execution model 
My approach with RS was slightly wrong: RS' TOP was always containing current
IP. It worked, but it was problematic when came the time to introduce
RS-modifying words: it's impossible to modify RS in a word without immediately
messing your flow.

Therefore, what used to be RS' TOS has to be a variable that isn't changed
midway by RS-modifying words. I guess that's why RS is called *return* stack...

a8e573c84a forth: add bin dict compilation stage! 
Big one.

This allows us to write higher order words directly in Forth, which is much
more convenient than writing post-immediate (see "NOT" structure in diff if
you want to see what I mean) structures in ASM.

These structures can then be written to ROM (rather than loaded in RAM for
definitions loaded at run-time).

That's quite a bit of tooling that was added, 2 compilations stages, but I
think it's well worth it.
