calcite git commit: [CALCITE-1527] Support DML in the JDBC adapter (Christian Tzolov)

Repository: calcite
Updated Branches:
  refs/heads/master 106dcc0fa -> 02752fe78


[CALCITE-1527] Support DML in the JDBC adapter (Christian Tzolov)

Extend CalcisteAssert to verify DML statements;
Resolve the RowType for SqlNode UPDATE consistently with the INSERT and DELETE;
Add field sourceExpressionList field to TableModify;
Implement DML for JDBC Adapter (i.e. DmlRel-To-Sql);
Make sure the ResultSetEnumerable keeps the statment/connection open.

Use same code path for INSERT ... VALUES and INSERT ... SELECT;
fix pretty-printing of INSERT ... VALUES (Julian Hyde).
