[svn-r11237] Purpose:

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.
