[SPARK-4608][Streaming] Reorganize StreamingContext implicit to improve API
convenience
There is only one implicit function `toPairDStreamFunctions` in
`StreamingContext`. This PR did similar reorganization like
[SPARK-4397](https://issues.apache.org/jira/browse/SPARK-4397).
Compiled the following codes with Spark Streaming 1.1.0 and ran it with
this PR. Everything is fine.
```Scala
import org.apache.spark._
import org.apache.spark.streaming._
import org.apache.spark.streaming.StreamingContext._
object StreamingApp {
def main(args: Array[String]) {
val conf = new
SparkConf().setMaster("local[2]").setAppName("FileWordCount")
val ssc = new StreamingContext(conf, Seconds(10))
val lines = ssc.textFileStream("/some/path")
val words = lines.flatMap(_.split(" "))
val pairs = words.map(word => (word, 1))
val wordCounts = pairs.reduceByKey(_ + _)
wordCounts.print()
ssc.start()
ssc.awaitTermination()
}
}
```
