### master
- Remove `Combinator` class in favor of combinator functions
- Remove `Resolver` class
- Remove superfluous Reactor function analogs
- Add `Reactor::onError()` exception handling hook
- Correctly exit `UvReactor` and `LibeventReactor` run loop when no outstanding watchers
remain active
- All `Promisor` implementations now require a `Reactor` constructor parameter.
Previously these implementations would lazy-inject the global singleton event
reactor instance if no reactor parameter was specified in the constructor.
- Add optional boolean `Reactor::tick($noWait)` parameter
**Additions**
- Added `Reactor::onError()` exception handling hook
- Added optional boolean `$noWait` parameter to `Reactor::tick($noWait)`
- Added `Amp\getReactor()` and `Amp\chooseReactor()` functions
**Bugfixes:**
- Correctly break out of the `NativeReactor` run loop immediately when
`Reactor::stop()` invoked inside immediately watchers.
`Reactor::stop()` invoked inside immediately watchers
- Correctly exit `UvReactor` and `LibeventReactor` run loop when no outstanding
watchers remain active
**Removals:**
- Removed `Combinator` class in favor of combinator functions
- Removed `Resolver` class, use `GeneratorResolver` trait internally
- `Promisor` implementations no longer have any knowledge of the event reactor.
**Deprecations:**
- Deprecated `Promise::wait()`. New code should use `Amp\wait()` to synchronously
wait for promise completion
- Deprecated `Amp\reactor()` function. New code should use `Amp\getReactor()`
instead
- The `ReactorFactory` class is deprecated and scheduled for removal. Please use
the `Amp\getReactor()` function instead of `ReactorFactory::select()`
> **BC BREAKS:**
- All the changes listed above are BC breaks -- please update code accordingly :)
- None
