[svn-r9959] Purpose: Bug fix

Description: For variable-length string, H5Tget_class returned H5T_STRING as
its class.  But H5Tdetect_class and H5Tget_member_class considered it as
H5T_VLEN.  This is fixed to let all these 3 functions treat it as H5T_STRING.
Some test cases have been added to dtypes.c


Platforms tested:  heping - already tested for v1.6 with h5committest

Misc. update:  RELEASE.txt

- For variable-length string, H5Tget_class returned H5T_STRING as its
class. But H5Tdetect_class and H5Tget_member_class considered it
as H5T_VLEN. This is fixed to let all these 3 functions treat it
as H5T_STRING. SLU - 2005/02/08
- The byte order of 1-byte integer types was fixed as little endian
even on a big-endian machine. This has been corrected. SLU -
