f4879ed96d Use jstream to serialize records to JSON format in S3Select (#7318)
- Also, switch to jstream to generate internal record representation
  from CSV/JSON readers

- This fixes a bug in which JSON output objects have their keys
  reversed from the order they are specified in the Select columns.

- Also includes a fix for tests.

2786055df4 Add new SQL parser to support S3 Select syntax (#7102)
- New parser written from scratch, allows easier and complete parsing
  of the full S3 Select SQL syntax. Parser definition is directly
  provided by the AST defined for the SQL grammar.

- Bring support to parse and interpret SQL involving JSON path
  expressions; evaluation of JSON path expressions will be
  subsequently added.

- Bring automatic type inference and conversion for untyped
  values (e.g. CSV data).
