h4h5tools

Purpose:
    Bug fix
Description:
    h5toh4 tests failed on SV1 and OSF1. It turned out that
    ttable.h5 contained "some weird" data with exponents -44 for float data
    and -315 for double data. On OSF1 the data caused floating exception for hdp,
    on SV1 data was completely screwed up during H5 read and H4 write operations.
Solution:
    Replaced the file with the new one that has reasonable data. Also
    used short for one of the fields datatypes instead of int, since the old
    file had two int fields and didn't have a short field.
Platforms tested:
    SV1, OSF1, arabica
