Code cleanup (sorta)
Description:
When the first versions of the HDF5 library were designed, I remembered
vividly the difficulties of porting code from a 32-bit platform to a 16-bit
platform and asked that people use intn & uintn instead of int & unsigned
int, respectively. However, in hindsight, this was overkill and
unnecessary since we weren't going to be porting the HDF5 library to
16-bit architectures.
Currently, the extra uintn & intn typedefs are causing problems for users
who'd like to include both the HDF5 and HDF4 header files in one source
module (like Kent's h4toh5 library).
Solution:
Changed the uintn & intn's to unsigned and int's respectively.
Platforms tested:
FreeBSD 4.4 (hawkwind)

Purpose:
check-in the second time to update the handling of data transfer in h4toh5.
This will make up for the cvs conflict checking a couple hours ago.

Purpose:
1) fix the implementation of image according to image specfication
2) fix two bugs of SDS implemention. the first one is
to handle the unlimited SDS with the first dimensional size set to 0.
the second one is to change the way how HDF5 dataset is written.
Description:
1) mapping 24-bit image to 3D arrays instead of 2D compound datatype.
2) previously forgot considering unlimited SDS with the size set to 0.
3) H5P_set_buffer seems not working well for a extremely small size.
Solution:
1) see above.
2) add a special case to deal with this.
3) don't use H5Pset_buffer.
Platforms tested:
RedHat Zoot 6.2

New Features!
Description:
Start migrating the internal use of property lists in the library from the
older implementation to the new generic property lists.
Currently, only the dataset transfer property lists are migrated to the
new architecture, all the rest of the property list types are still using
the older architecture.
Also, the backward compatibility features are not implemented yet, so
applications which use dataset transfer properties may need to make the
following changes:
H5Pcreate(H5P_DATASET_XFER) -> H5Pcreate_list(H5P_DATASET_XFER_NEW)
and
H5Pclose(<a dataset transfer property list>) -> H5Pclose_list(id)
This still may have some bugs in it, especially with Fortran, but I should
be wrapping up those later today.

Fixing a boo-boo
Description:
There was a problem with the generated Dependencies file. It listed
the H5pubconf.h header file as being in the $(top_srcdir) directory
when it's in the $(top_builddir) directory.

Regenerated it.

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)

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.

Purpose:

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]

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.
