Override Read methods in PeekableStreamReader to avoid unpredicted behaviour (#183)
* Watcher: Add onClosed event and callback
* Update the code generators to accept the onClose callback
* Re-generate API

* Fix unit test
* Watcher fixes/improvements:
- Run Task.Yield at the beginning to make sure we're running async
- Set Watching = false before invoking OnClosed, to make sure the callers see a consistent state.
* Fix flakey tests by converting them to async and synchronizing code blocks
* Use the same timeout for all tests
* Use signals to gracefully shut down the mock server
