Optimized the vsite threading
On many threads a significant part of the vsites would end up in
the separate serial task, thereby limiting scaling. Now two weakly
dependent tasks are generated for each thread and one of them uses
a thread-local force buffer, parts of which are reduced by different
threads that are responsible for those parts.
Also the vsite setup now runs multi-threaded.
