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.

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

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...

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).
