Two external MPI libraries are now created: libmpi.la and libmpi_abi.la. Backend code that was originally in libmpi.la has been extracted into libopen-mpi.la to be linked into both libraries. Parts of the Open MPI C interface are now being generated by a python script (abi.py) from modified source files (named with *.in). This script generates files for both the ompi ABI and the standard ABI from the same source file, also including new bigcount interfaces. To compile standard ABI code, there's a new mpicc_abi compiler wrapper. The standard ABI does not yet include all functions or symbols, so more complicated source files will not compile. ROMIO must be disabled for the code to link, since it's relying on the external MPI interface. Signed-off-by: Jake Tronge <jtronge@lanl.gov>
Implement lots of missing functionality in the original api.py script. The functionality is now part of the bindings generation framework used for Big Count. Number of todos still to do, in particular provide support for wrapping user supplied callback functions. Also, the sendrecv_replace, etc. code needs to be refactored to work with the bindings framework. Signed-off-by: Howard Pritchard <howardp@lanl.gov>

Two external MPI libraries are now created: libmpi.so and libmpi_abi.so.
Backend code that was originally in libmpi.la has been extracted into
libopen-mpi.la to be linked into both libraries.
Parts of the Open MPI C interface are now being generated by a python
script (abi.py) from modified source files (named with *.in). This
script generates files for both the ompi ABI and the standard ABI from
the same source file, also including new bigcount interfaces.
To compile standard ABI code, there's a new mpicc_abi compiler wrapper.
The standard ABI does not yet include all functions or symbols, so more
complicated source files will not compile. ROMIO must be disabled for
