feat(v4.0.0): the wire in the engine -- whole messages, put and taken in one step

Browse Source 
Queues of whole messages on the wires between nodes (v4/wire.h), the six
addresses and ten operations a node asks of the fabric (MESH.md 7d.3), and the
fabric's pool of queues. Engine only: the nucleus does not use any of it yet.
The ports in the host map move to BUF0_W - 140 so that the new addresses are
not among the nucleus variables, with a compile-time check.
