Calcite’s first major release.

Since the previous release we have re-organized the into the org.apache.calcite namespace. To make migration of your code easier, we have described the mapping from old to new class names as an attachment to [CALCITE-296].

The release adds SQL support for GROUPING SETS, EXTEND, UPSERT and sequences; a remote JDBC driver; improvements to the planner engine and built-in planner rules; improvements to the algorithms that implement the relational algebra, including an interpreter that can evaluate queries without compilation; and fixes about 30 bugs.
