including the merge of `hdffv/hdf5/develop`, back to the branch that Vailin and
I share.
Now I need to put this branch on a fork with a less confusing name than
vchoi_fork!
Added windows name suffix for debug to CMake cmd_arg for examples and test.
Fix issues discovered under debug testing;
Create a version of H5Iget_name that correctly returns the name.
Rework PIN_JAVA_STRING macro and usage to eliminate possible memory leaks by using if-else instead of mid-routine return.
Update example to use new H5Iget_name API.
Tested: windows under debug
