Move tests in the same directory as the corresponding code, so it's easier to see what is/isn't tested. Fix naming of libcutils_tests (plural) to match the singular that's more common (even though the plural makes more sense to me). Add these two to system/core/'s TEST_MAPPING. Remove obsolete AndroidTest.xml. Fix a flaky (timing-dependent) libcutils test. Test: ran tests Change-Id: I7e0a31ff45c8a152562bf66fc97161594249366e
