Fixes mergeN-drain
nip-spec done, fixed due the other fixes in lib

Fix all but the last of the compress tests

The problem here was that emitAll(collect(..., FULL_FLUSH)) was called even

Fix "inflate.uncompressed input" test
removed interrupt None case which was I think oversight there
removed Process.state
added piped process1 onComplete and fixed process1.liftY
toList doesn't throw Kill
