Code speedups, etc.
Description:
Bring in new algorithms and data structures for dealing with hyperslabs.
This speeds up the hyperslab I/O for non-regular hyperslabs by a huge
amount.
Currently, the new API functions are ifdef'ed out, pending discussion
and consensus approval.
Platforms tested:
FreeBSD 4.4 (hawkwind)

Bug fix
Description:
H5S_select_elements is not actually putting the new point on the list of
points selected when there are no points currently selected and the
'append' operation is chosen.
Solution:
Add new point to list correctly.

FreeBSD 4.4 (hawkwind)

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)

Update
Description:
Changed
#include <hdf_file.h>
construct to
#include "hdf_file.h"
so that the GNU compiler can more easily pick up the dependencies
which it places in the .depend and Dependencies files. Also
regenerated the Dependencies to go along with this.
Platforms tested:
Linux

Code cleanup.
Description:
Fixed _lots_ (I mean _tons_) of warnings spit out by the gcc with the
extra warnings. Including a few show-stoppers for compression on IRIX
machines.
Solution:
Changed lots of variables' types to more sensible and consistent types,
more range-checking, more variable typecasts, etc.
Platforms tested:
FreeBSD 4.2 (hawkwind), IRIX64-64 (modi4)

Purpose:
Parallel Bug Fixes
Description:
Was out of sync with header file re-arrangements I checked in last night.
Solution:
Fixed to use new header files, etc.
Platforms tested:
O2K (modi4)

Maintainance & performance enhancements
Description:
Re-arranged header files to protect private symbols better.
Changed optimized regular hyperslab I/O to compute the offsets more
efficiently from previous method of using matrix operations.
Added sequential I/O operations at a more abstract level (at the same level
as H5F_arr_read/write), to support the optimized hyperslab I/O.
Platforms tested:
Solaris 2.6 (baldric) & FreeBSD 4.1.1 (hawkwind)
