Add optional pool for the UDPPacketBuffer objects that handle all incoming UDP data.
Even when an avatar is standing still, it's sending in a constant stream of AgentUpdate packets that the client creates new UDPPacketBuffer objects to handle. This option pools those objects. This reduces memory churn. Currently off by default. Works but the scope can be expanded.
