Add permission by identifying uuid (owner/creator/group) and function. Revoke
permission in the same manner. Permission adjustments immediately effect
running scripts ability to call os functions.

This is to achieve a clean separation of concerns - the watchdog is an inappropriate place for work management.
Also adds a WorkManager.RunInThreadPool() class which feeds through to Util.FireAndForget.
Also switches around the name and obj arguments to the new RunInThread() and RunJob() methods so that the callback obj comes after the callback as seen in the SDK and elsewhere
This is somewhat more in keeping with something like osForceAttachToOtherAvatarFromInventory()
and potentially allows a separate osForceSit() command with High threat rather than VeryHigh that only sits the owner and can be enabled without enabling sit of other avatars.
Allows a script IN the target prim to force an avatar to sit on it using normal methods as if called by the client.
Overload method of osForceSit() to allow a script NOT in the target prim to force an avatar to sit on the target prim using normal methods as if called by the client.
This patch is based on previous work from
http://opensimulator.org/mantis/view.php?id=4492
and also includes the suggestions from justincc including change of threat level
Thank you Christos Lightling.
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()
As per http://wiki.secondlife.com/wiki/LlSetStatus
Setting STATUS_BLOCK_GRAB_OBJECT prevents or allows move of a physical linkset by grab on any prim.
Setting STATUS_BLOCK_GRAB prevents or allows move of a physical linkset by grab on a particular prim.
Previously, setting STATUS_BLOCK_GRAB would prevent drag via all prims of the linkset.
As per http://msdn.microsoft.com/en-us/library/system.random%28v=vs.100%29.aspx, the .NET Random class is not thread-safe.
If called by multiple threads at once, methods may return 0.
Except for llRand(), other OpenSimulator code did not lock before calling a shared Random instance.
This commit adds a ThreadSafeRandom class that extends Random but does internal locking so that it is thread-safe.
This change is invisible to existing callers and the explicit locking in the llFrand() implementation is now redundant.
This means the presence info may be out of date by up to 20 seconds, but this avoids scripts potentially triggering constants requests to user accout and presence info services.
Relates to http://opensimulator.org/mantis/view.php?id=7088 though I fixed in a different way.
Adds regression test for this case.
These are identical to llCreateLink() and llBreakLink() except that they don't require script permissions.
However, osForceCreateLink() still requires that linked and linkee still have the same owner.
There's also an AutomaticLinkPermission setting in [XEngine] that could be set to true to prevent the LSL function checks.
But this doesn't allow the finer control over which users/scripts, etc. can do this that the OSSL functions provide.
