h4h5tools

Due to recent changes of macro names in HDF4(MAX_NC_NAME to H4_MAX_NC_NAME etc),
h4h5tools failed in compiling. I have updated some h4toh5 tool macro names so that they don't directly rely on HDF4 library. To make h4h5tools back compatible with old HDF4 library, Macro names are changed to depend on MAX_???? if MAX_???? is defined.

Tested on Kagiso.
