I'm restoring the info function pointers to the IO module but allowing the function pointers to be NULL (eg in ompio). And letting romio321 set its function pointers for those routines. This means the info system uses the new OMPI-level info system for most things, but skips it and uses the pre-existing romio info system just for the romio module. It's possible to convert romio, but I went a ways down that path and found it kind of convoluted. Having pointers from the lower level ADIO_File back to the higher level ompi_file_t wasn't too bad, but I got stuck trying to figure out where/how to register the infosubscribe_subscribe callbacks vs the way initial k/v values are scattered around the romio code currently.
