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

following for the rationale:

Note that mpi.h only receives AC_DEFINE's (not AC_SUBST's), so we
still have to AC_DEFINE to get the value in there -- so we AC_DEFINE
something that we give to a typedef.

restoring the PMPI version. A variety of reasons for this:
- mpi.h was blinding using inline in a C header without the configrue mojo
properly set it, as mpi.h doesn't include ompi_config.h. This eventually
would have caused a borked build.
- mpi.h and mpif.h were never updated to not include PMPI_W{tick,time} as
a proper prototype
- The C++ and F90 bindings didn't do the right things when there was no
PMPI version of the C call, but profiling was enabled
- Since we only use gettimeofday, the function call overhead really doesn't
matter
This should probably go to the 1.0 branch

friendly #defines to be included in mpi.h (even for users), such as
_GNU_SOURCE, which can have some really big consequences on Linux.
Instead, add mpi.h to AC_CONFIG_HEADERS and just include the #defines
we have to have for mpi.h and the C++ bindings.
