GRADLE-2839 Map Ivy wildcard configuration mapping to all public configurations of target module, rather than all (public + private) configurations.
GRADLE-2842 Don't schedule tasks that are in the `unknown` state when building the task graph.

These are tasks that have been referenced via a soft dependency but not added to the graph or referenced via a hard dependency.
Fixed int test for changes to the IvyFileModule fixture.
GRADLE-2825 - remove logging for duplicate files.
Merge remote-tracking branch 'remotes/origin/release'
