New test player stub to load mock native players.
Added a new class TestPlayerStub that takes a magic url in the setDataSource call.
Based on the value of the url, the stub is going to load a DL and create the concrete
player used during the test.
After these initialization steps TestPlayerStub is just a wrapper.
Added a new functional test MediaPlayerInvokeTest to demonstrate how a new
mock player to test the invoke method can be loaded.
Added a new mock player for the invoke test: invoke_mock_media_player.cpp.

+// Wrapper around a test media player that gets dynamically loaded.
+//
+// The URL passed to setDataSource has this format:
+//
+// test:<name of the .so>?url=<url for the real setDataSource impl.>
+//
+// e.g:
+// test:invoke_test_media_player.so?url=http://youtube.com/
+// test:invoke_test_media_player.so?url=speedtest
+//
+// TestPlayerStub::setDataSource loads the library in the test url. 2

+// player and one to destroy it.
