[SPARK-23598][SQL] Make methods in BufferedRowIterator public to avoid
compilation for a large query
## What changes were proposed in this pull request?
This PR fixes compilation error regarding a large query when a generated
code has split classes. The issue is `append()`, `stopEarly()`, and other
methods are not accessible from split classes that are not subclasses of
`BufferedRowIterator`.
This PR fixes this issue by making them `public`.
Before applying the PR, we see the following exception by running the
attached program with `CodeGenerator.GENERATED_CLASS_SIZE_THRESHOLD=-1`.
```
test("SPARK-23598") {
// When set -1 to CodeGenerator.GENERATED_CLASS_SIZE_THRESHOLD, an
exception is thrown
val df_pet_age = Seq((8, "bat"), (15, "mouse"), (5,
"horse")).toDF("age", "name")
df_pet_age.groupBy("name").avg("age").show()
}
```
Exception:
```
