Improve symbol name mangling of zlib and HDF5

[dzenanz]

While trying to compile a program which uses both ITK and NetCDF (which in turn depends on HDF5 and zlib), I ran into the following linking errors:

I am quite convinced this is due to incomplete symbol mangling in zlib-ng and itk_hdf5_mangle.h.
