Purpose:
H5Pset_szip -- major rewrite
H5Dcreate -- added a note regarding SZIP
Description:
H5Pset_szip -- Rrestructured and rewrote H5Pset_szip Description and
Notes to explain SZIP usage more completely, to capture limitations
and potential pitfalls, to offer a tunign suggestion, and to
segregate discussion of SZIP parameters that may be of interest to
users familiar with SZIP in other environments.
Updated parameter discussion in Description and Parameter sections.
Described ways in which erroneous SZIP setup can cause H5Dcreate
to fail.
H5Dcreate -- Added note to see the H5Pset_szip RM entry if H5Dcreate
fails and SZIP compression is to be used with the dataset.

Purpose:
Bug Fix
Description:
If an HDF5 file grows larger than its address space, it dies and is unable to
write any data. This is more likely to happen since users are able to change
the number of bytes used to store addresses in the file.
Solution:
HDF5 now throws an error instead of dying. In addition, it "reserves" address
space for the local heap and for object headers (which do not allocate space
immediately). This ensures that after the error occurs, there is enough address
space left to flush the entire file to disk, so no data is lost.
A more complete explanation is at /doc/html/TechNotes/ReservedFileSpace.html

Purpose:
To more carefully describe the behavior of H5Pset_external.
Description:
Add notes that first H5Pset_external call sets the dataset as EXTERNAL
and identifies the first file in the series of external files that
will hold the dataset; subsequent calls identify additional files;
all external files must be declared before the dataset is created;
and the library will create files that don't yet exist on the system
at the time that H5Dwrite is called to write data to that file.
Also a few copy edits.

Code optimization & bug fix
Description:
When dimension information is being stored in the storage layout message
on disk, it is stored as 32-bit quantities, possibly truncating the dimension
information, if a dimension is greater than 32-bits in size.
Solution:
Fix the storage layout message problem by revising file format to not store
dimension information, since it is already available in the dataspace.
Also revise the storage layout data structures to be more compartmentalized
for the information for contiguous, chunked and compact storage.

Purpose:
Bugfixes in H5Gset_comment, h5gget_comment_f, and h5gset_comment_f.
(Follow-on to the H5Gget_comment bugfix of last week.)
Description:
Changed C parameter descriptions to indicate the following:
'loc_id' can be file, group, dataset, or named datatype.
'name' can be '.' if 'loc_id' fully describes the object.
'name' is ignored if 'loc_id' is a dataset or named datatype.
Modified h5gget_comment_f and h5gset_comment_f notes accordingly.
Copy edits in H5Gget/set_comment and h5gget/set_comment_f.

'loc_id' can be file, group, dataset, or named datatype.
'name' can be '.' if 'loc_id' fully describes the object.
'name' is ignored if 'loc_id' is a dataset or nemed datatype.
Also corrected the fact that the 'name' parameter description
referred to setting the comment rather than retriving it.

Purpose:
Update documentation index (hdf5/doc/html/index.html) to say
that it describes Release 1.6.2.
The index file included with the R1.6.2 source tarfile mistakenly
refers to Release 1.6.1; this has been noted on the "Known Problems"
page on the HDF5 website. The corrected file will be included in the
hdf.ncsa.uiuc.edu:/HDF5/doc/ document set and in the
Release 1.6.2 documentation-only tarfile.

Bug fix/optimization
Description:
Address slowdown in MPI-I/O file metadata operations that was introduced
mid-stream. We now _require_ a POSIX compliant parallel file system for the
MPI-I/O file driver (as well as for the MPI-POSIX file driver).
Also optimized file open operation when the file is being created by
reducing the number of collective & syncronizing calls.
