Add scratch data field in constraint matrix to avoid frequent re-allocation that can affect parallel performance (memory allocation is not scalable). It is made thread-local and we need to make sure that no function used inside distribute_local_to_global spawns tasks by itself. There is a bool state variable to provide some security against race conditions, even though it is subject to race conditions, too.

In the beginning the Universe was created. This has made a lot of people very angry and has been widely regarded as a bad move.
