Detailed Description

Send FetchInventoryReply information to clients asynchronously on a single thread rather than asynchronously via multiple threads.

If the main root inventory is right-clicked on a version 1 viewer for a user with a large inventory, a very very large number of FetchInventory requests are sent to the simulator. Each is handled on a separate thread by the IClientAPI, but the sheer number of requests overwhelms the number of threads available and ends up freezing the inbound packet handling.

This class makes the first FetchInventory packet thread process the queue. If new requests come in while it is processing, then the subsequent threads just add the requests and leave it to the original thread to process them.

This might slow down outbound packets but these are limited by the IClientAPI outbound queues anyway.

It might be possible to ignore FetchInventory requests altogether, particularly as they are redundant wrt to FetchInventoryDescendents requests, but this would require more investigation.
