ConvertToI420 and ConvertToARGB support the use of a negative height parameter to flip the image vertically. When converting from NV12 or NV21 this parameter was misinterpreted, resulting in invalid output. This CL introduces the use of abs_src_height to correctly calculate the location of the source UV plane. The sign of crop_height is not used, to reduce confusion ConvertToI420 and ConvertToARGB no longer accept negative crop height. Unit tests for Android420ToI420 are updated to fix miscalculation of src_stride_uv, fix incorrect pixel strides, and to test inversion. New unit tests are included to test inversion for ConvertToARGB, ConvertToI420, Android420ToARGB, and Android420ToABGR. For consistency the test NV12Crop is renamed ConvertToI420_NV12_Crop.
