*** Original change description ***

Add a new toolchain type for c++.  In order to do this, PlatformConfiguration is made a legal configuration fragment for every rule class.

Add a default "dummy" c++ toolchain to prevent resolution errors when legacy toolchain selection logic is used.  Add toolchain mocks to java and shell tests.
