This has two aims
1) Reduce initial teleport failures when a foreign Hypergrid user enters a region by not holding up the teleport for attachment rez (this can be particularly costly when HG gets all assets in the object graph.
2) Reduce server load that may impact other simulator activities.
This complements existing JobEngine options that perform initial login attachment rez and appearance send in consecutive tasks.
Job engine is controlled via "debug jobengine start|stop|status".
Can only currently be enabled and disabled dynamically at runtime.
Currently only applies to code sending initial region data (objects, other avatar data) to a client.
The functionality is the same but this allow us to monitor such tasks via "show threads" and abort them for test purposes, etc.
Also extends thread names to provide more info (e.g. SendInitialDataToClient says what client the task is for).
Other parts of OpenSimulator are relying on SP.Velocity == 0 for vehicles.
So add and use SP.GetWorldVelocity() instead when we need vehicle velocity, along the same lines as existing SP.GetWorldRotation()
Rapid polls are more expensive than triggered events (several polls vs one trigger) and may be problematic on heavily loaded simulators where many threads are vying for processor time.
A triggered event is also slightly quicker as there is no maximum 200ms wait between polls.
This is already going to be correctly set by WaitForUpdateAgent() earlier on in that method, which is always called where a callback to the originating region is required.
Allows experiments in manually reducing updates under heavy load.
Activated by "debug scene set client-upd-per" console command.
In a simple test, can send as few as every 4th update before observed movement starts becoming disturbingly rubber-banded.
Another manifestation of this bug is that after a Hypergrid teleport, when you click on one of the avatar's attachments the object doesn't show its name. This means that the viewer knows the attachment is there, but the simulator does not.
The problem was caused by treating Hypergrid teleports as if they're Logins (because the teleport flag ViaLogin is enabled).

This caused the client to stop responding, and even the simulators to have problems. The solution is to disallow crossing before the previous cross has completed.
For non-root prim, eye offsets now need to be made relative to root prim if either camera-at or camera-eye are set.
Probably a regression since November 2013 when all sits were made relative to root prim to match viewer expections (and fix other bugs).

This was due to a silent uint overflow in ScenePresence.UpdateChildAgent() corrupting child agent positions
when the child agent was in a region with a greater x or y map co-ord than the root agent region
Probably introduced in beeec1c.
This still will not function properly with very high region map co-ords (in the millions) but other parts of the code don't handle this properly anyway.
Looks to address http://opensimulator.org/mantis/view.php?id=7163
This uses an offset of 0.05 on the up vector of the sit orientation, after extensive analysis on
http://opensimulator.org/mantis/view.php?id=7096 and https://wiki.secondlife.com/wiki/Talk:LlSitTarget
This supersedes the previous adjustment in 5b73b9c4 which had been wrongly applied.
The maximum change is about 0.1 with a maximum height avatar.
This patch is all Aleric's work - I am applying manually in order to add these additional notes
When an avatar is in their home grid, their name appears as "First Last". In other grids the name appears as "First.Last @grid.example.com". However, viewers have a bug and they don't always show the new name. We use a trick (changing the Group Title briefly) in order to make the viewers show the new name. This is only done after a Hypergrid teleport.
to the physics engine.
This operation was accidentally removed while in the middle of improving
the computation of the avatar height. This is a temp fix until the real
solution is added.
Also fixes an issue where sitting avatar counts became inaccurate after any cross.
Part of the problem was due to cloning code using MemberwiseClone() but not resetting certain collection structures.
Adds regression test for this case.
In relation to http://opensimulator.org/mantis/view.php?id=7050
Recent versions of Firestorm and Singularity have started sending the viewer name in the 'Channel' field, leaving only their version number in the 'Viewer' field. So we need to search both of these fields for the viewer name.
This resolves http://opensimulator.org/mantis/view.php?id=6952
