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.

c515720e23 Revert "Remove link.fs"
Let's revisit the relinking approach, with LITA this time.
This reverts commit 6652125d47.

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).

Memory mapping is a dead end too, solution has to be at a higher

Not quite functional yet, but works in toy situations. The goal is to
concatenate RC2014's bootstrapped dict to the boot binary.
