[Opensim-dev] Changes in inventory interface and Simian backend

[Diva Canto]

Hi,

Over this past week I made an overhaul of how inventory is initially 
downloaded. The code was extremely inefficient, and often led to 
inventory stalling (http://opensimulator.org/mantis/view.php?id=7054). 
In order to make things more efficient I added two additional methods to 
the inventory service interface that allow fetching multiple things at 
once. This made download times for large inventories be slashed to a 
small percentage of what they have been -- depending on size and how 
many links there are in the inventory, the download times now may be as 
small as 1%-30% of what they were before. (The more links, the more 
drastic the improvements will be)

I'm not entirely sure how the Simian backend deals with inventory -- if 
it proxies it through the simulator or if it uses a capability URL 
directed at the inventory service. If the former, things will be 
functional but will continue to be inefficient until someone brings the 
Simian connector up to date with the new functions. Doing this requires 
changes in the backend itself, which I'm not in a position to do.

Please look at the changes introduced in 
SimianInventoryServiceConnector, and it will be clear what needs to be 
done on both sides of the network.
