Add coroutine support to BehaviorDelegate

Per https://stackoverflow.com/a/56664610/132047

Since it's possible for certain dispatchers to completely avoid yielding, and currently the immediate dispatchers exhibit this behavior, we need an alternate mechanism of forcing suspension or UndeclaredThrowableExceptions will still be seen.

Retrofit does not have its own thread pool onto which we can defer resuming. Instead we rely to Dispatchers.Default and forcibly suspend the caller using low-level coroutine intrinsics.

The XML format changed again, so I decided to switch us to Checksytle's
curated 'Google Style Guide' format which seems like a reasonable
enough default for us.

Add synchronous exception workaround for Response requests

Because of a race condition caused by thread preemption, this can sometimes happen. Explicitly yield to ensure the exception is delivered asynchronously to the continuation.

Avoid synchronous checked exceptions in 'suspend fun's

Allow service interfaces to extend other interfaces

With a higher minSdkVersion, the bug which prevented this on Android no longer exists.

Use Objects.requireNonNull instead of custom helper
