Reimplementing much of the DefaultPromise methods

Optimizations:
1) Avoiding to call 'synchronized' in tryComplete and in tryAwait
2) Implementing blocking by using an optimized latch so no blocking ops for non-blockers
3) Reducing method size of isCompleted to be cheaper to inline
4) 'result' to use Try.get instead of patmat
