Hack in console command "debug lludp toggle agentupdate" to allow AgentUpdate in packets to be discarded at a very early stage.

Enabling this will stop anybody from moving on a sim, though all other updates should be unaffected.
Appears to make some cpu difference on very basic testing with a static standing avatar (though not all that much).
Need to see the results with much higher av numbers.
