### What problem does this PR solve?
Issue Number: None
Related PR: None
Problem Summary: Hive CSV external tables that use TextInputFormat should
keep one record per physical line. The current CSV reader can continue scanning
across line delimiters when an enclosure remains open, which produces wrong
query results for quoted values containing newlines.
### Release note
Fix wrong results when querying Hive CSV external tables with quoted
newlines.
### Check List (For Author)
- Test: No need to test (will be run separately by the user)
- Behavior changed: Yes (Hive CSV external table queries now stop at
physical line boundaries instead of merging lines through an open quote)
- Does this need documentation: No
