BulletSim: scale the force for external AddForce by the simulation
...
step time so it will be applied completely the next step. The internal
AddForce routine does not scale the force.

BulletSim: Rename some of the interface structures (BulletWorld, ...)
...
to get ready for...
Start creation of BulletAPITemplate. This defines the abstract interface
functions. Following commits will move over to the new interface.
This will enable switching between the managed and unmanaged version of
Bullet.

BulletSim: Default avatar density changed to 3.5 which is WAY closer
...
to the SL value.
Fixed frictin values for physical materials which were just wrong
which caused things that should have slipped to not.

BulletSim: Fix single physical prim reporting its mass as zero.
...
Properly return root mass as mass of just the root prim rather
than the mass of the linkset. SOG has the logic to add the masses
together to get the linkset mass.
Update TODO list.

* Initial commit of BulletSimN (BulletSNPlugin). Purely C# implementation of BulletSim. This is designed to be /as close as possible/ to the BulletSim plugin while still being entirely in the managed space to make keeping it up to date easy as possible (no thinking work). This implementation is /slower/ then the c++ version just because it's fully managed, so it's not appropriate for huge sims, but it will run small ones OK. At the moment, it supports all known features of BulletSim. Think of it like.. POS but everything works. To use this plugin, set the physics plugin to BulletSimN.

BulletSim: Fix llApplyImpulse so it works after the first impulse. The problem was Bullet deactivating the object between the pushes (when, as far as the physics engine is concerned, it isn't moving).

BulletSim: add BSPhysObject code to manage registrations of preStep events. Use same to implement setForce and setTorque so the values are restored at the beginning of each step (since Bullet zeros forces applied last step). Simplify implementation of AddForce and AddTorque by relying on the addition of forces in Bullet.

Disable UDPPacketBuffer pooling for now to resolve an issue on Windows of interference between incoming packets.
...
On Windows, concurrent multi-threaded processing of inbound UDP somehow allows different data input processing to interfere with each other.
Possibly the endpoint reference is being switched, though I don't yet know the mechanism. Not seen on Mono.
Also resolveable by setting RecyclePackets = false or RecycleBaseUDPPackets = false in [PacketPool]
Or async_packet_handling = false in [ClientStack.LindenUDP]
For now, will simply disable this particular pooling though will revisit this issue.

BulletSim: apply friction to linear and angular motion before returning advanced motor value. This seems to be the problem with BulletSim vehicles turning too quickly. Also removed the configuration parameter that controlled the timestep scaling kludge for angular velocity that was added to research the question of quick turning.

Extend default 1 second wait for event completion to other thread script reset (as called by llResetOtherScript()).
...
As with script stop (via llDie()) aborting other scripts event threads, llResetOtherScript() can also abort any current event thread on another script.
On mono 2.6, 2.10 and possibly later this may cause locking problems in certain code areas.
This commit reuses the recently introduced [XEngine] WaitForEventCompletionOnScriptStop to make this a 1 sec timeout, rather than 0 secs.

BulletSim: fix vehicles going underground when unsat. Problem was that, when doing unsit, the order of operations on the prims and the vehicle is very chaotic and not in a good order so the root prim was being left physical and thus it fell for a bit. Also changed default of velocity scaling to be closer to the movement standard.

BulletSim: add parameter to UpdateProperties call into the linkset so changes from the physics engine can be differentiated from changes made by the user. This eliminates a linkset rebuild loop. Also add logic to not rebuild or freak out when the object/linkset crosses a terrain boundry.

BulletSim: experimentally remove unit displacement from prim border crossing test. This seems to cause border crossing to be sensed either a little early or a little late depending on which directin the object is moving. If border crossings become totally borked or someone remembers why this was displacement was done, revert this change.
