[PROPOSAL] Fix HDF4 library naming / organizational scheme

[derobins]

PROBLEM

The Autotools and CMake have very different ideas about how to name and organize their output.

From the Autotools (shared/Java/XDR - Fortran built separately as static)
bin

Note the differences:

• CMake adds -shared to tools linked against the shared library
• CMake creates libhdf vs Autotools libdf
• Autotools sonames differ
• CMake puts the Fortran wrappers in separate libraries

PROPOSED FIX

• Drop "-shared" from shared tools
• Uniform names (how do we handle libhdf vs libdf? - maybe use libhdf and symlink libdf)
• The Autotools should create separate Fortran libraries like CMake and support shared libraries

HOW WOULD USERS BE AFFECTED?

PRO
➕ CMake and Autotools products would have identical names
➕ Autotools Fortran output would be more modern, more like HDF5 (support shared, easier to bring improvements over)

CON
➖ Some users may be unhappy with the new names
