Added new gmock-based MockFilterHost and deprecated the old one.

Updated FileDataSource tests to use the new MockFilterHost as a proof of concept, also because my pipeline refactoring completely broke the test.

BUG=16008
TEST=FileDataSourceTest.* should pass

-// The corresponding FilterHost implementation for MockPipeline.  Maintains a
-// reference to the parent MockPipeline and a reference to the Filter its
-// hosting.  Common usage is to check if the hosted filter has initialized by
-// calling IsInitialized().
+//
+// A FilterHost implementation based on gmock.  Combined with setting a message
+// loop on a filter, permits single-threaded testing of filters without
+// requiring a pipeline.
+//
+// TODO(scherkus): Remove old_mocks::MockFilterHost as soon as other tests have
+// transitioned over to the new gmock-based MockFilterHost.
