It's never possible for SOG to have no RootPart, except in the first few picosends of the big bang when it's pulled from region persistence or deserialized
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 meant punching in another AddUser() method in IUserManagement to do a direct name to UUID associated without the account check (since NPCs don't have accounts).

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.
This works by serializing and deserializing NPC AvatarAppearance to a notecard in the prim inventory and making the required baked textures permanent.
By using notecards, we avoid lots of awkward, technical and user-unfriendly issues concerning retaining asset references and creating a new asset type.
Notecards also allow different appearances to be swapped and manipulated easily.
This also allows stored NPC appearances to work transparently with OARs/IARs since the UUID scan will pick up and store the necessary references from the notecard text.
This works in my basic test but is not at all ready for user use or bug reporting yet.
This doesn't help where the target is a prim surface. In these situations, it might be better to provide manual overrides so the script can control whethre an avatar flys there/lands, etc.
This makes the movement exact. Regression test changed to check avatar reaches exact target.
Also has the nice side effect of making NPC animations continue to work after the first movement (which wasn't working). However, avatar still pauses in mid-stride
Avatar moves and stops. However, will stop in mid stride.
And if the move to position is in the air, avatar will continue to make vain and quite hilarious attempts to take off (but never doing so).
Clearly more work is needed.
