[svn-r9856] Purpose: New test and minor bug fix

Description:  Fixed a bug related to user-define functions for derived floating-point data type, like
H5Tset_fields, H5Tset_offset, H5Tset_precision, H5Tset_size.  Added test for these functions and test
for data type conversion between derived floating-point types.


Platforms tested: h5committest and fuss
