[svn-r603] Changes since 19980818
----------------------

./src/H5.c
        Fixed an argument promotion bug in HDfprintf()

./src/H5Fistore.c
        Fixed a array bounds read error.

./src/H5HG.c
        Fixed uninitialized (but unused) data appearing in the hdf5
        file, a potential security problem.

./src/H5T.c
./src/H5Tpublic.h
        Added new data types for hdf5 types: H5T_NATIVE_HSIZE,
        H5T_NATIVE_HSSIZE, H5T_NATIVE_HERR, and H5T_NATIVE_HBOOL. I
        did not add H5T_NATIVE_HID since I couldn't think of a reason
        that it would be stored in a file anyway.
