refactor(v4.0.0): the capsule's inner words keep their state in memory

Browse Source 
WORD, the dictionary words and the code generator run underneath
whatever the user has on the stacks, which are ten and nine deep (D-2).
Measured, they used five to seven data cells of their own, leaving a
line about three.  Each now keeps what it works on in its file's
scratch cells and has at most three cells on the data stack; , calls
nothing; and the longest chains of calls are shorter.

The public words of core.v4, input.v4 and dict.v4 get dictionary
headers.  NUMBER is split so the interpreter can have a flag instead of
NODE-ERROR.  The host-node tests share one memory map, host_map.h.
