Trimm out now unused option LK_EXCLUPGRADE from the lockmgr namespace.
This option just adds complexity and the new implementation no longer will support it, so axing it now that it is unused is probabilly the better idea. FreeBSD version is bumped in order to reflect the KPI breakage introduced by this patch. In the ports tree, kris found that only old OSKit code uses it, but as it is thought to work only on 2.x kernels serie, version bumping will solve any problem.
