Changed to sourceforge tdb code. This includes spinlocks (so we now have a --with-spinlocks option to configure, this does mean the on-disk tdb format has changed, so 2.2alphaX sites will need to re-create their tdb's. The upside is no more tdb fragmentation and a +5% on netbench. Swings and roundabouts.... Jeremy. (This used to be commit 9dea7b7c257db487f8ced7dad3fce92fba03ea91)
