This was because attributes were not being included in the transformation, hence losing the script state identity.
Symptoms are messages like "[SCENE OBJECT GROUP]: SavedScriptState element had no UUID in object test box"
Regression since the conference code merge. Regression test extended for this case.

The document here has no <?xml declaration. Though ideally it may be present, in practice it has not been added as the data here is embedded within an asset
On Mono 3.2.8 and probably other versions, calling WriteEndDocument() without a declaration does nothing.
On Windows .NET, the same operation throws a "Document does not have a root element" exception which may be contributing to Mantis 7397 and possibly 7439
This matches Linden Lab behaviour and what was already possible via shift-copy.
Transfer would not apply here as the owner and copier are the same.
This is the only functional change, all other current take copy logic remains the same.
Adds regression tests around relevant take copy cases.
This UUID gatherer provides a superset of the previous gatherer's functionality
as it also allows the caller to control gathering iterations for load purposes.
This is because objects with lots of parts can have a lot of xml to load into memory, and this has been seen to have a noticeable performance impact.
Whereas streaming has been seen to reduce the impact in normal serialization.
Implmentation is messy but I couldn't see a better way of doing it when you can't assume that you know the exact structure of the input XML.
Attachment persistence is not handled in this way and this just results in a load of busy work until a check in each SOG terminates a backup check for attachments anyway.
Reading large XML documents (e.g. complex attachments) is CPU expensive - this must be done as few times as possible (preferably just once).
Reading these documents into XmlDocument is also more resource intensive than using XmlTextReader, as per Microsoft's own publication "Improve .NET Application Performance and Scalability"
Optimization of other cases will follow if this change is successful.
are kept on another. When users rez items from inventory or take objects from world, an HG-like asset copy takes place between the 2 servers, the world asset server and the user's asset server. This makes the simulators independent of the central asset server.
Note that this an advanced configuration and requires some security strengthening coming up.
Changed UuidGatherer to use 'sbyte' to identify assets instead of 'AssetType'. This lets UuidGatherer handle Materials, which are defined in a different enum from 'AssetType'.
Also, fixed a bug: when rezzing a coalesced object from a prim's inventory, apply the coalesced object's name and description only to the first sub-object; not to all the objects in the coalescence. (This was already done correctly when rezzing from a user's inventory.)
Fix issue where objects rezzed from Trash or Lost And Found then be placed back in the respective folder when taking the object or a copy back into inventory.
This fixes the combined bounding box location for regions bigger than 256x256.
It also fixes the position on taking coalesced objects in the non-root regions, where position checks are properly done on rez instead.
It also fixes the megaregion land channel to return null if the land does not exist, which should probably also be done for the ordinary land channels rather than returning a dummy region.
Inspiration from Garmin's commit in http://opensimulator.org/mantis/view.php?id=6595. Thanks!
