Summary

Part 5 of 8 of the split of #34. It moves the shell/fragment broadcast protocol into the core, and the Angular sinks, host and log provider become @Injectable subclasses of the core's.

Changes

• The broadcast sink, host, log provider and wire messages move to the core.
• The sink and the log provider can share one connection. enabled: false wins over a shared connection, and so does dispose(): they send nothing, a disposed provider answers queries with [] at once, and the connection stays open for its other users.
• In 'broadcast' mode the Angular sink and log provider share one channel per injector.

How to review

The wire fixture from part 1 is unchanged and still passes: every pairing of an Angular or core shell with an Angular or core fragment sends the same messages, so separately deployed shells and fragments need not upgrade together.
