HDF5 datasource - header file collision between KST and libhdf5-dev

[gsmecher]

There is a preprocessor macro collision between KST and libhdf5:

#ifndef HDF5_H
#define HDF5_H

[...]

#endif

This collision occurs in the following files:

• /usr/include/hdf5/serial/hdf5.h (Debian libhdf5-dev 1.10.8+repack1)
• kst/datasources/hdf5/hdf5.h (KST master)

I recommend changing datasource/hdf5/* to datasource/hdf5/datasource_* and altering the preprocessor macros to match.
