opal layer. Add a check against a maximum (actually get rid of ifs internally to opal_bitmap.c) -- the functionality to set the current maximum size opal_bitmap_set_max_size() is currently only used in attribute.c to set the maximum OMPI_FORTRAN_HANDLE_MAX... Tested on linux/x86-64 with intel-tests with all_tests_no_perf_f run with 6 procs. Let's look into MTT as well... This commit was SVN r20708.
