It appears that at least Singularity 1.8.5 (but probably others) rely on attachment FromItemIDs being different to display more than one.
This commit resolves this by generating random IDs instead of always using UUID.Zero for NPCs.

The part reverted is from commit 2ebb421.
Unfortunately, IAvatarFactoryModule.SetAppearance() does not transfer attachments.
I'm not sure how to do this separately, unfortunately I'll need to leave it to Dan :)
Regression test added for this case.

This is required to stop a race where the SensorRepeat module can detect an NPC avatar before m_avatars is populated.
Extending the lock is the easiest to understand solution rather than getting complicated with null checks.
Hopefully resolves http://opensimulator.org/mantis/view.php?id=5872
This allows NPCs to be sensed as agents by LSL sensors rather than as a specific NPC type (which is currently an OpenSimulator-only extension).
Wiki doc on this and other recent NPC functions will follow soon
This is to partially address http://opensimulator.org/mantis/view.php?id=5769
We don't need to call SP.HandleAgentSit() again if we are within 10m since the autopilot won't trigger.
By calling it twice, the position of the sitting NPC was wrongly adjusted, ending up near <0,0,0>.
However, this change does mean that NPCs further than 10m away will not attempt to autopilot to the prim, though this code was broken anyway (is actually a different mechanism to normal NPC movmeent).
Hopefully this can be addressed soon.
Format is osNpcSit(<npc-uuid>, <target-uuid>, OS_NPC_SIT_IMMEDIATE)
e.g. osNpcSit(npc, llGetKey(), OS_NPC_SIT_IMMEDIATE);
At the moment, sit only succeeds if the part has a sit target set.
NPC immediately sits on the target even if miles away - they do not walk up to it.
This method is in development - it may change so please don't trust it yet.
Standing will follow shortly since that's kind of important once you're sitting :)
I thought that I had implemented this but must have accidentally removed it.
Adds a regression test to detect if this happens again.
Temporarily disables automatic landing of NPC at a target. Will be fixed presently.
The approach here, as in other parts of OpenSim, is to return a copy of the list rather than the attachments list itself
This prevents callers from forgetting to lock the list when they read it, as was happening in various parts of the codebase.
It also improves liveness.
This might improve attachment anomolies when performing region crossings.
This is done by introducing a PresenceType enum into ScenePresence which currently has two values, User and Npc.
This seems better than a SaveAttachments flag in terms of code comprehension, though I'm still slightly uneasy about introducing these semantics to core objects
Default for this function is now not to automatically land.
This allows better control by scripts when an avatar is going to be landing on a prim rather than the ground.
Stopping the avatar involves faking a collision, to avoid the pid controller making it overshoot.
A better approach would be to gradually slow the avatar as we near the target
this is to allow walking on prims. it will be up to the script writer to be sure that there is a continuous path.
currently implemented in osNpcMoveToTarget(), but none of this is final.
