complete, but stable enough that it will have no impact on general development, so into the trunk it goes. Changes in this commit include: - Remove the --with option for disabling MPI-2 onesided support. It complicated code, and has no real reason for existing - add a framework osc (OneSided Communication) for encapsulating all the MPI-2 onesided functionality - Modify the MPI interface functions for the MPI-2 onesided chapter to properly call the underlying framework and do the required error checking - Created an osc component pt2pt, which is layered over the BML/BTL for communication (although it also uses the PML for long message transfers). Currently, all support functions, all communication functions (Put, Get, Accumulate), and the Fence synchronization function are implemented. The PWSC active synchronization functions and Lock/Unlock passive synchronization functions are still not implemented This commit was SVN r8836.
