* Add starpu_bcsr_filter_vertical_block filtering function.
* Add starpu_interface_copy2d, 3d, and 4d to easily request data copies from data interfaces.
* Move optimized cuda 2d copy from interfaces to new starpu_cuda_copy2d_async_sync and starpu_cuda_copy3d_async_sync, and use them from starpu_interface_copy2d and 3d.
* New function starpu_task_watchdog_set_hook to specify a function to be called when the watchdog is raised

* MPI: new functions starpu_mpi_interface_datatype_register() and starpu_mpi_interface_datatype_unregister() which take a enum starpu_data_interface_id instead of a starpu_data_handle_t
* New script starpu_env to set up StarPU environment variables
