[SPARK-7943] [SPARK-8105] [SPARK-8435] [SPARK-8714] [SPARK-8561] Fixes multi-database support
This PR fixes a set of issues related to multi-database. A new data structure `TableIdentifier` is introduced to identify a table among multiple databases. We should stop using a single `String` (table name without database name), or `Seq[String]` (optional database name plus table name) to identify tables internally.
