b73e1a5f7a z80a: invert the meaning of IFZ, IFNZ, IFC, IFNC, 
It is much less confusing when "IFZ," means "If Z is set, continue
into IF, else, jump to THEN,".

add3b6629b Make DO .. LOOP binary code more compact 
Only a few bytes saved in forth1.bin, but the DO .. LOOP construct
isn't used much yet. It's still significant savings per LOOP call.

It makes the tool much more versatile. I'll have adev being included
in all recipes, so it can be assumed.

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.

420836276d readln: rename (c<) to (rdln<) 
so that it isn't picked up automatically at boot. Only when (c<$) is
called do we override (c<). This fixes tricky boot problems.

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).
