Branch working on #359

I'll continue committing to this until all the varargs are replaced.

Observable.from: refactor varargs to overloads

ReactiveX#359 Varargs cause compiler warnings

Observable.concat: refactor varargs to overloads

ReactiveX#359 Varargs cause compiler warnings

As part of this I also changed this:

```java
public static <T> Observable<T> concat(Observable<Observable<? extends T>> observables)
```

to

```java
public static <T> Observable<T> concat(Observable<Observable<T>> observables)
```

I documented the reasoning of this at ReactiveX#360 (comment)

This seems to be working well so am merging it. This removes all vararg usage. It does increase surface area with multiple-arity overloads, but it's clean and displays well in an IDE.

I have chosen to use Observable<Observable<T>> on all of the overloads instead of Iterable<Observable<T>> since Observable is more generic and fits the Rx model. An Observable<Observable<T>> can easily be created from Iterable<Observable<T>> using Observable.from. If this is not liked we can add the Iterable overloads as well.
