Added H5Pget_data_transform
Added support for polynomial data transforms
Description:
There is now support for polynomial data transforms (ie, (2+x)*(x-5)) instead
of just linear ones.
Note that, in order to compute a polynomial transform, one temporary copy of
the original data must be stored for each occurence of "x" in the transform
expression. This can result in very high memory usage for expressions of high
order.
Platforms tested:
sol + eirene

Bug fix.
Description:
Fixed handling of trivial data transform expressions (like 5/3 + 3) and some
data coversion fixes. Also added more tests to dtransform.c
Solution:
Added some more checks in the H5Z_xform_reduce_tree function to see if perhaps
the transform expression is complicated and is a non-trivial reduction.
Added tests for data conversion to dtransform as well as tests for a trivial
data transform expression.
Platforms tested:
h5committest'ed, except used arabica instead of sol and didn't do on copper
b/c no logon there. Problem noted with mtime test...doesn't appear to be
related to anything having to do with data transforms.

Code cleanup/new features
Description:
Switch over to a new style for registering filters with the library -
instead passing in an ID, a string and a callback function to H5Zregister,
the client should pass in a single pointer to a H5Z_claass_t struct which
contains the ID, the description string and all the function callbacks as
fields.
Added support for a new "can apply" callback for each filter, which is
called when a dataset is created to check whether the parameters for that
filter apply correctly to the combination of the datatype and the chunk size
(i.e. dataspace) for the dataset.
Added support for a new "set local" callback for each filter, which
is called when a dataset is created (after the "can apply" filter callback)
and sets filter parameters that are specific to that particular dataset.
Switched the filters we ship over to use the new H5Z_class_t struct for
their internal registrations and also added "set local" callbacks to the
szip and shuffle filters and a "can apply" callback to the szip filter.
Lots of other code cleanups, etc. also

To support szip compression in HDF5
Description:
szip compression support is required by NASA ESDIS. The compression algorithm
is good for scientific data. In HDF5, we add another filter
function to make szip as a default compression package as we did for gzip(or zlib).
In this check-in, a new function called H5Pset_szip was added into H5Pdcpl.c, this
function is very similar to H5Pset_deflate. The only difference is SZIP needs
four parameters from the user to get the compression done while gzip needs only one.
So we pass a pointer to this function instead of an integer number.
The description of the four parameters of szip should be in different
documents.
H5Z.c and other header files were simply modified to have HDF5 know szip.
Solution:
See the decription
Platforms tested:
Since there are changes of configure.in and configure,I didn't use h5committest.
I tested with four platforms.
1) Linux 2.4 (eirene)
2) Solaris 2.7(arabica)
3) windows 2000(VS 6.0)
4) SGI IRIX6.5-64(modi4)
For test 1)-3), only basic C tests were done
For modi4 test, I tested 64-bit C,parallel and fortran.
All tests passed, except a warning message from szip library when checksum is used in some order, which doesn't cause any real problems.

Code cleanup
Description:
Changed hard-coded magic number (32) for the maximum number of filters
in a filter pipeline to use a symbolic constant (H5Z_MAX_NFILTERS)
instead. This limit could (and probably should) be removed to allow an
unlimited number of filters in a pipeline.

Purpose:
__DLL__ is a keyword in some platforms and __DLL__ is also defined as a macro for windows DLL applications.

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)

Changed
#include <hdf_file.h>
construct to
#include "hdf_file.h"

which it places in the .depend and Dependencies files. Also
regenerated the Dependencies to go along with this.

./src/H5.c
Fixed more dependency problems in H5_term_library(). There was
a bug in the previous version that could cause the wrong EOF
marker to be written to the boot block under certain
circumstances. Hopefully this fixes it although I don't ready
access to a test case (Mark Miller will test it).
./src/H5F.c
./src/H5Fprivate.h
Added an H5F_close_all() that is similar to
H5F_term_interface() but which doesn't close the
interface. Files that don't have open object headers are
closed, others are delayed until all object headers close. All
files are flushed.

Added two extra arguments to H5Pget_filter() in order to
retrieve the filter name. The name is the name registered for
the filter with H5Zregister(), but if the dataset creation
property originally came from an existing file then the name
is that which is stored in the file.
./tools/h5ls.c
The `-v' option now prints the names of the filters.

H5MM_malloc(0) and H5MM_calloc(0) actually allocate a single

./src/H5S.c
./src/H5Sselect.c
Fixed pointer->integer conversions in error return values in
three places.

Added timing support. When compiled with H5T_DEBUG defined
the library will print conversion bandwidths when the library
closes. The H5Tregister functions take a string as the first
argument so the statistics output is meaningful.
./MANIFEST
Added new files.
./configure.in
./src/H5config.h.in
Check for getrusage(). Check for compress2() in libz.a and

./src/H5B.c
./src/H5Bprivate.h
./src/H5Gnode.c
./src/debug.c
Cleaned up some indentation and added support to print istore
B-trees. From the debugger, give the B-tree address and the
dimensionality from the layout message of the object header.
./src/h5ls.c
The oid is printed as w:x:y:z where w and x are the file ID
and y and z are the OID within the file. You can give z or
y*2^32+z as an argument to the debugger to print the object
header for the object.
./src/H5AC.c
Cleaned up statistics and made them match those reported by
H5T and H5Z.
./src/H5MM.c
./src/H5MMprivate.h
./src/H5Fistore.c
Finally got rid of a couple of long-standing const cast
warnings.
