Takeshi Yamamuro f2b3525c17 [SPARK-22771][SQL] Concatenate binary inputs into a binary output ... ## What changes were proposed in this pull request? This pr modified `concat` to concat binary inputs into a single binary output. `concat` in the current master always output data as a string. But, in some databases (e.g., PostgreSQL), if all inputs are binary, `concat` also outputs binary. ## How was this patch tested? Added tests in `SQLQueryTestSuite` and `TypeCoercionSuite`.
