The filesystem object was available through ModuleContext.Fs(), but gives too much access to the filesystem without enforicing correct dependencies. In order to support sandboxing the soong_build process move the filesystem into the Config. The next change will make it private. Bug: 146437378 Test: all Soong tests Change-Id: I5d3ae9108f120fd335b21efd612aefa078378813
