A TreeList.T is the thread that traverses the client's directory
tree, and sends its list of files to the server's Tree Differ.
proto is the descriptor describing the version of the protocol
that is being used.
wr is the output stream to the Tree Differ.
collections is a sequence of supfile records specifying which
collections and releases to transfer.
compLevel specifies the compression level to use.
If a reaper is given, it will be notified just before the thread
terminates.
If stats is specified, the tree lister will maintain various
statistics in the given object. It will call the start method
initially, then the update method after each update of the
statistics, and finally, the finish method just before terminating.
Debugging information is written to the trace stream, if specified.
END TreeList.
