[SPARK-16101][SQL] Refactoring CSV read path to be consistent with JSON
data source
## What changes were proposed in this pull request?
This PR refactors CSV read path to be consistent with JSON data source. It
makes the methods in classes have consistent arguments with JSON ones.
`UnivocityParser` and `JacksonParser`
``` scala
private[csv] class UnivocityParser(
schema: StructType,
requiredSchema: StructType,
options: CSVOptions) extends Logging {
...
def parse(input: String): Seq[InternalRow] = {
...
```
``` scala
class JacksonParser(
schema: StructType,
columnNameOfCorruptRecord: String,
options: JSONOptions) extends Logging {
...
def parse(input: String): Option[InternalRow] = {
...
```
These allow parsing an iterator (`String` to `InternalRow`) as below for
both JSON and CSV:
```scala
iter.flatMap(parser.parse)
```
## How was this patch tested?
Existing tests should cover this.
