Introduced a build convention of projects prefixed with “internal-” being regarded as not for public consumption. Right now, this means not including them in the Gradle distribution and not requiring Javadocs like public projects.
The “testing” project has been renamed to “testingInternal” under this new convention.
Moved core/src/test and core/src/integTest into new “testing” module which contains all fixtures/utilities for testing support. This module is not part of the Gradle distribution. See the build script for this module for more info.
