Tried to standardize sizes and added #defines to H5Fpkg.h so that hopefully
the code is a little easier to read.
Of course this is a file format change.

When using the latest version of the file format, move the "modification
time" information into the object header prefix, which is more efficient.
Also add "access time" and "change time" (for metadata) fields, all of which
take about the same space as the previous modification time header message.

This feature is still in progress; Shared Object Header Messages are not
complete as a feature and are not thoroughly tested. There are still
"TODO" comments in the code (comments with the word "JAMES" in them,
so as not to be confused with other TODO comments).
Hopefully this checkin will reduce the liklihood of conflicts as I finish
implementing this feature.
All current tests pass on juniper, copper (parallel), heping, kagiso, and mir.

int64_t is only

Moved definition of int64_t from H5private.h to H5public.h as a temporary

Add 'loookup3' checksum routine and switch to using it for metadata
checksums - it's just as "strong" as the CRC32 and about 40% faster in general
(with some compiler optimizations, it's nearly as fast as the fletcher-32
algorithm).

Users can create external links using H5L_create_external(). These links
point to an object in another HDF5 file. Users can alter the behavior of
external links or create new kinds of links by registering callbacks
using the H5L interface.
Added tests, tools support, etc.
Also a number of other, minor changes have been made (some restructuring of
the H5L interface, for instance).
Additional documentation and examples are forthcoming.

Bug fix.
Description:
Some machines (e.g., HPUX) will have off64_t defined but no support
for stat64 unless certain LargeFile macro is turned on. This caused
the last fix on H5private not quite right which caused compiling failures.
Solution:
Added stat64 and fstat64 tests and then will use them only if they
are supported.
Platforms tested:
Tested on kelgia, copper and heping (pll).
(Compiling alright but tests for kelgia and heping are not done.
expect no problems.)

bug fix.
Description:
Previous H5private.h would attempt to use the off64_t/stat64/etc
by checking just sizeof __INT64 being 8. This caused errors in
some machines like alpha cluster which is a 64bit machine. Its
compiler supports the type __int64 but it does not support
off64_t since its off_t is already 64bits big. The above code
casued the compiler to complain about the unknown off64_t and
such.
Solution:
H5private.h:
Changed the code to use the pseudo standard of off64_t/stat64/etc
only if sizeof(off_t) is not 64 bits AND sizeof(off64_t) exists
and is 64 bits. This assumes if off64_t is defined, all those
stat64, fstat64, etc are supported too.
configure.in:
configure:
Added the testing of sizeof(off64_t) to support the above solution.
Platforms tested:
h5committested. Also tested at LANL QSC.

Description:
The file size test in C++ library failed on Copper because the
value returned by h5_get_file_size was intepreted incorrectly
due to different interger sizes.
Solution:
H5private.h: Added check to use stat64 and off64_t where appropriate.
h5test.c and h5test.h: used h5_stat_size_t in place of off_t.
tattr.cpp: used h5_stat_size_t in place of off_t.

portibility issue to windows
Description:
setvbuf on visual studio 2005 needs the size to be greater or equal to 2.
<description of setvbuf from msdn library>
Buffer size in bytes. Allowable range: 2 <= size <=
INT_MAX (2147483647). Internally, the value supplied
for size is rounded down to the nearest multiple of 2.
h5import used linebuffer option of setvbuf for stderr and stdout and the size is
0 by default. This causes core dump with visual 2005 on windows 64-bit.
Solution:
1. Use HDsetvbuf inside h5import.c,
2. Define HDsetvbuf inside windows H5pubconf.h for windows to work around
the core dump of h5import test. This is probably a bug inside visual studio 2005.

Description: Unix remove function removes only the latest version of a file
on VMS. Some of our tests create multiple versions of the testfiles
and as a result, test programs may be confused, give false negative result,
etc.
Solution: Created HDremove_all function for VMS that removes all versions of the files.
HDremove on VMS is an alias to HDremove_all.
Platforms tested: VMS server and heping (to check that nothing is borken on UNIX side)

Description:

Bug fix/Feature
Description:
Modify the library to use rand_r, when available, instead of srand. If
rand_r is not available, it will try to use srandom/random, and then finally
fall back to srand/rand.
Solution:
A couple places in the library use the srand() function to seed the random
number generator. This can cause problems on certain platforms and could theoretically
cause problems for users who expect a certain sequence of random numbers following their
own call to srand().
Most platforms have an implementation of rand_r, which is identical to rand, except that
it allows for explicit storage of the seed value. The configure script will now check
for the existence of rand_r to facilitate its use in the library.
Two new functions are added, to replace the macros HDsrand/HDrand. These functions are HDrand and
HDsrand. HDrand will call rand_r, if available, or random(), if available, and fall back to rand() if neither
of those is available. HDsrand will store the seed value locally, if rand_r is available. Otherwise, it will call
srandom if available, and fall back to srand otherwise.
Platforms tested:
heping, mir. Really need to test on Red Storm, since that platform motivated this fix, but the machine
is currently not available.

Cleanup.
Description:
Removed the home-made version of snprintf and vsnprintf since they
do not actually enforce the size parameter correctly and could corrupt
memory or as a security hole.
This block of code has been turned off since Aug 11, 2005 for all platforms
except Tflops. No one has reported any problem since--sort of empirical
evidence that all platforms except Tflops support both functions.
Tflops has retired in September. So, no need to keep this block of code.
Also, fixed the HDxxx macro to call the corresponding xxx function.
Platforms tested:
Tested in heping, both serial and parallel.

This initiates the "unstable" phase of the 1.7.x branch, leading up

with it - the format will change again before the release and you will not
be able to read your old files!!!
WARNING!!!! WARNING!!!! WARNING!!!! WARNING!!!! WARNING!!!! WARNING!!!!
WARNING!!!! WARNING!!!! WARNING!!!! WARNING!!!! WARNING!!!! WARNING!!!!
Solution:
There's too many changes to really describe them all, but some of them
include:
- Stop abusing the H5G_entry_t structure and split it into two separate
structures for non-symbol table node use within the library: H5O_loc_t
for object locations in a file and H5G_name_t to store the path to
an opened object. H5G_entry_t is now only used for storing symbol
table entries on disk.
- Retire H5G_namei() in favor of a more general mechanism for traversing
group paths and issuing callbacks on objects located. This gets us out
of the business of hacking H5G_namei() for new features, generally.
- Revised H5O* routines to take a H5O_loc_t instead of H5G_entry_t
- Lots more...
