Purpose:
New features for adding attribute options and modifying testing files

Purpose:
new features
Description:
1. add an option to convert HDF4 file without HDF4 specified attributes such as
HDF4_OBJECT_TYPE, HDF4_REF_NUM etc.
it can be done by inputting "h4toh5 -na input.hdf"
The default converter will still keep HDF4 specfied attributes.
2. Add compression features (gzip) for image too. Now the compressed HDF4 image
can be supported by using HDF5 gzip. Not sure whether tools can read it. Need to be tested.
3. Change SPACEPAD to NULLTERM for HDF4 dimensional name list. We can use variable length HDF5 string to represent these names, however currently H5dump and H5view cannot support variable length HDF5 string. converter will wait for other tools' update.
Solution:
Platforms tested:
eirene(Red Hat 6.2) and arabica(solaris 2.7)

Solution:
Platforms tested:
eirene
[machines you have tested the changed version. This is absolute
important. Test it out on at least two or three different platforms
such as Big-endian-32bit (SUN/IRIX), little-endian-32(LINUX) and
64-bit (IRIX64/UNICOS/DEC-ALPHA) would be good.]

Purpose:
a bug fix
Description:
User can define "Real Vdata" as user-defined attribute. By using VSisattr, we can check this out. In order to keep this piece of information, We use "Vdata attribute" in the converted HDF5 file to distingush this kind of Vdata from independent Vdata.
Solution:
see above
Platforms tested:
eirene(Linux)

Purpose:
a bug fix
Description:
When Vsisattr is true, this Vdata still needs to be converted as an independent
real "Vdata", We will add object type of this vdata as "Vdata attribute".
Solution:
erease the evaluation of Vsisattr call.

Purpose:
bug fix Adding more features
Description:
Bugs: 1) hdf4 dimensional scale data can be none, but the dim name can still defined by users, so number of hdf4 dimensional names and number of object reference may be different
Previously, this problem is not considered.
2) SDcheckempty will return true when fill value is set to HDF4 SDS, and then fill value information is lost
3) check whether SDS have fill value set although SDcheckempty return true.
Use H5Psetfillvalue and H5Dcreate in HDF5 part, still needs to wait for the new development of HDF5 and also need to investigate whether this part of code has bugs.
New features: compressed SDS will get compressed with gzip when it is converted. That will save some space.
[describe the bug, or describe the new feature, etc]
Solution:
See above and design document

Purpose:
a bug fix
Description:
when creating sds dimensional scale dataset, I accidently created two sds dimensional scale dataset with the same name, (say using name "dim1" for both rank 2 and rank 3).
hdf4 library doesn't give me complaints, hdp dumpsds doesn't generate complaints. h4toh5 converter since assumed that dimensional scale name has to be unique, simply skip if finding the same dimensional name, so accidently the result from hdp dumpsds are the same as the result from h5dump until I implement library API and find this bug.
Solution:
make unique sds dimensional scale name for this test file. Will also need to modify testfiles later.
suggestions: somebody check hdf4 library to disallow the same dimensional scale nameOused for the same sds object.
Platforms tested:
eirene, and this check in will not affect daily test.
