Revert "Corrected all Java interfaces declarations"

[zsxwing]

Reverts #2807

Revert because they are breaking changes. RxScala needs the public modifier so that it can wrap them into Scala classes.

All interface methods are public and abstract regardless of whether you declare them.
All interfaces are static when nested regardless of whether you declare it.

Is this some kind of Scala compiler bug?

No. I thought they were different. But since the byte codes are same, it won't break RxScala.

LOL, it just can't be true, many Scala apps depend on Java code without public abstract modifiers in interfaces, I think it's a problem of mixing concepts "Interface" in Java and "Trait" in Scala, everything should work without these modifiers

Right. Thank you.
