Add a new filter bitmap for UMP groups for reducing the unnecessary read/write when the client is connected to UMP EP seq port. The new group_filter field contains the bitmap for the groups, i.e. when the bit is set, the corresponding group is filtered out and the messages to that group won't be delivered. The filter bitmap consists of each bit of 1-based UMP Group number. The bit 0 is reserved for the future use.
