New Feature. Description: Added code and changes so that h5perf (pio) can be built by standalone mode (that is built by just "h5pcc" without all these internal files.) With the standalone mode, h5perf can be built against different versions of hdf5 library and to contrast the performance among them. (Note that pio_standalone.c and pio_standalone.h are used in standalone build only.) Platforms tested: Tested in copper and heping.
