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)

"temporary buffer"
code, since the functionality was superceded. See the followup document for
details on the free-list code.

to accept a
location ID (i.e. a file or group ID) as well as the dataset ID. This should
allow Dave to get the palettes stored in the file correctly and also enable
Bob and/or Bruce's indexing stuff. This change should be folded into the
documentation for these three functions for the release.
Also, I fixed a number of bugs in the hyperslab and point selection
iterators for H5Diterate and they are working correctly now.

to add tests
for now. Also, I revised some of the code for hyperslab I/O, which should
provide a modest speedup in situations with lots of hyperslabs.

Removed __unused__ from forward function declarations.
./src/H5P.c
Removed a comment about restrictions for the type conversion
temporary buffers. Thanks to Quincey, the comment no longer
applied.
./src/H5T.c
Relaxed the H5Tpack() a little so it would pack compound data
structures that had non-transient atomic members.
./tools/h5ls.c
Added a `-g' (or `--group') flag that causes information to be
printed about the specified group instead of the group's
contents. (sort of like Unix's `ls -d'). The `-g' can be used
in combination with `-r' to print information about the group
and its contents.

Most of these changes are because the `interface_initialize_g'
variable change from hbool_t to int. It's a one line change.
Changed the way the library is closed so we have more control
over the order the interfaces are shut down. Instead of
registering an atexit() function for every interface in some
haphazard order we just register one: H5_term_library() which
then calls the H5*_term_interface() functions in a
well-defined order.
If the library is closed and then reopened repeatedly by
calling H5close() and H5open() in a loop we only add one copy
of the library termination functions with atexit().
Termination is a two-step process in order to help detect
programming errors that would cause an infinite loop caused by
the termination of one interface waking up some other
previously terminated interface. The first step terminates
the interface and *marks it as unusable*. After all
interfaces are terminated then we mark them all as usable
again. The FUNC_ENTER() macro has been modified to return
failure or to dump core (depending on whether NDEBUG is
defined) if we try to call an interface while it's shutting
down.
./src/H5.c
The H5dont_atexit() function returns failure if it's called
more than once or if it's called too late. However, the error
stack is not automatically printed on failure because the
library might not be initialized yet
./test/chunk.c
./test/flush1.c
./test/flush2.c
./test/iopipe.c
./test/overhead.c
./test/ragged.c
Changed the extra cast for Win32 so we do floating point
division again -- it was just confusion about precedence and
associativity of casting and the C coercion rules. Removed
extra carriage returns inserted by broken operating system.
./src/H5Ffamily.c
Fixed an bug where H5F_fam_write() lowered the EOF marker for
one of the family members causing H5F_fam_read() to read
zeros.

./test/external.c
Support library for test files. This isn't done yet but
Katie's contractions are ~10 minutes apart so I figured I
better back this stuff up just in case I'm not here next
week...
Eventually all test files will understand HDF5_DRIVER to name
the low level file driver and parameters so we can easily test
various drivers. They will also understand HDF5_PREFIX to
prepend to the beginning of file names which is necessary for
testing ROMIO with various drivers. Also, the cleanup function
will know how to use the file name prefix and will understand
different file driver naming schemes like file families. I'm
not sure they'll understand the `gsf:' type prefixes yet.
Note, the external test is completely commented out because
I'm in the middle of modifying it. It will still compile and
run but it doesn't test anything at the moment.

./INSTALL.parallel [NEW]
We're beginning to unify some of the parallel installation
steps. This file will contain general information for
installing the parallel library. It's not complete yet.
./configure.in
./configure [REGENERATED]
./src/H5config.h.in [REGENERATED]
Check for xdr_int() in libnsl required on Solaris when linking
with hdf4. It's found on the Irix system I tested which
complains that `-lnsl' didn't resolve any symbols. Oh well.
Fixed the order of searching for libdf and libmfhdf for hdf4
linking.
./configure.in
./configure [REGENERATED]
./src/H5config.h.in [REGENERATED]
./src/H5Z.c
Check for compress() in libz in order to find older versions
of the library that will still work for hdf4. Added a
separate check for compress2() that hdf5 will use.

Added checks for Posix.1g types like `int8_t'. If not defined
then H5private.h defines them. Changed all `int8' etc. to
`int8_t'.

Calling H5*_term_interface() resets interface_initialize_g to
FALSE so a subsequent call to H5open() (implied or explicit)
reinitializes global variables properly.
./src/H5private.h
./src/H5Oefl.c
./src/H5S.c
Changed MAX_SIZET, MAX_SSIZET, MAX_HSIZET, and MAX_HSSIZET to
SIZET_MAX, SSIZET_MAX, HSIZET_MAX, and HSSIZE_MAX to they
match the Posix.1 constants in <limits.h>.
./src/H5T.c
./src/H5Tconv.c
./src/H5Tpkg.h
./src/H5Tprivate.h
./src/H5detect.c
Added 36 more integer hardware conversion functions to the
type conversion table for conversions to/from `long long' and
`unsigned long long'. The `long long' names will be changed
shortly to make them portable to Win32.
Changed H5T_init() to H5T_native_open() and added an
H5T_native_close() to open and close the predefined native
data types.
Increased the initial size of the type conversion table from
64 to 128 entries.
Reordered the 90 new integer conversion functions so the names
that are printed favor `int' over `short' or `long' when two
of them are the same.
./test/dtypes.c
Added hardware and software integer conversion tests for the
56 functions I added recently but not the additional 36
checked in this time. That will come next.
Call H5close() after each test so type conversion statistics
are easier to follow. Try this: $ HDF5_DEBUG=t ./dtypes
Added more debugging output for when things go wrong.
./src/H5private.h
Removed trailing carriage-returns inserted by broken operating
system ;-)

Plugged a memory leak in the union of hyperslabs code.
Checkpointing dataset region references, which are working, but not stored in
file yet.
