Subject: Add object count stats for new IncomingPacket and UDPPacketBuffer
 pools if they are enabled.  Add count stats for existing LLUDP pool.

This introduces a pull stat type in addition to the push stat type.
A pull stat takes a method on construction which knows how to update the stat on request.
In this way, special interfaces for pull stat collection are not necessary.
