This does a couple opportunistic cleanups:

  • Adds some lint suppressions regarding the recent synthetic accessor changes
  • Create full disposable observers with documented no-op completions. This gives us two things:
    • A minor perf improvement by less objects by creating one single observer rather than two consumers + LambdaObserver and the inner bits of doOnEvent (three-ish allocs). This saves about 5 allocations per subscribe in total. Relates to Measuring runtime performance #105
    • Closes API Change Discussion: Switch to Single instead of Maybe #101. After thinking on it quite a bit, I think Maybe makes sense. There are some cases where the lifecycle is deferred and may resolve to be "unbound". I've also added an unbound() factory to TestScopeProvider to mimic this.

This changes the lifecycle subscriptions to use full observers to save some allocations, and also documents the noop on completions
