Cockroach Community License (ccl) Functionality

This tree is intended to house our non-Apache2 licensed Go packages. By convention, all packages under this tree have the suffix ccl.

Grouping CCL packages into one tree and clearly labeling all CCL packages with a recognizable suffix will hopefully make it easier to identify and prevent introducing any accidental dependencies on ccl from Apache2 packages.

C++ CCL code lives in c-deps/libroach/ccl.
