Working on another feature for the S3 storage engine

Brian has written a library that implements "XML Row Storage", and has added it to his HTTP Storage Engine.

I've got a couple of hours to add it to my S3 Storage Engine.

I've already stumbled over the fact that my engine as it was won't build against a very recent MySQL 5.1 source tree. Type byte is now uchar, and the call parameters of get_server_by_name have changed.
