Start a new tile request list.

In order to support the asynchronous receipt of terrain tile data over a network, we use a model whereby we build a request list of tile data, send that list, and then use the new tile data as it is received from the server. This model can of course be easily applied to local disk access also.

We build the request list by making a call to tsmTileReqBegin, then making multiple calls to tsmTileReqAdd to specify all of the tiles that we want to receive, then we call tsmTileReqEnd.

Once we have called tsmTileReqEnd then we can start reading in the tiles as they are received (trivial from local disk!) by calling a function such as tsmReadNextTile.

If you start a new request list before you have read in all of the tiles from a previous request list, then the previous request list will be thrown away in favour of the new list.
