Add small interface to "wrap" a static buffer (usually on the stack), but
still allow for buffers larger than the static buffer to be allocated. This
can eliminate _many_ short-lived buffer allocations in situations where the
buffer is a predictable size (or at least a "very likely" size).
Also, some minor code cleanups, particularly in the SOHM caching code.

company. The I/O is optimized when the source and destination
members are a subset of each other one way or another, and
the order is the same, and no conversion is needed. For example:
struct source { struct destination {
TYPE1 A; --> TYPE1 A;
TYPE2 B; --> TYPE2 B;
TYPE3 C; --> TYPE3 C;
}; TYPE4 D;
TYPE5 E;
};
or
struct destination { struct source {
TYPE1 A; --> TYPE1 A;
TYPE2 B; --> TYPE2 B;
TYPE3 C; --> TYPE3 C;
}; TYPE4 D;
TYPE5 E;
};
The optimization is simply moving data from the source to the
appropriate places in the buffer and bypass the reading of
the background data and data conversion.
Tested on smirom, liberty, sol, and copper.

Optimize a special case when the source members are a subset of
destination, and the order is the same, and no conversion is needed.
For example:
struct source { struct destination {

}; TYPE4 D;
TYPE5 E;

The optimization is simply moving data to the appropriate

Finish new version of the I/O pipeline message, which is much smaller than

Add "use the latest format" support for dataspace object header encode/
decode routines and clean up format a bit for the latest format (new to 1.8.x
releases)
Remove storing 'perm' parameter for array datatypes in memory and the file,
and add test to make certain that if any user applications are attempting to
store them, we get some reports back. (Should be unlikely, since the RefMan
says that the parameter is not implemented and is unsupported).
Carry those changes into the tests, etc.
Clean up a bunch more compiler warnings.

Description: Mac OS 10.4 on PowerPC chip has some errors to convert (unsigned)
long long to long double. When the bit sequences are 0x003ff..., 0x007fff...,
0x00ffff..., 0x01ffff..., 0x7fffff..., the converted values are twice as big
as they should be.
Solution: Detect the error in configure and disable the compiler conversion
and test case.

New feature
Description:
Check in baseline for compact group revisions, which radically revises the
source code for managing groups and object headers.
WARNING!!!! WARNING!!!! WARNING!!!! WARNING!!!! WARNING!!!! WARNING!!!!
WARNING!!!! WARNING!!!! WARNING!!!! WARNING!!!! WARNING!!!! WARNING!!!!
This initiates the "unstable" phase of the 1.7.x branch, leading up
to the 1.8.0 release. Please test this code, but do _NOT_ keep files created
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...
Platforms tested:
h5committested and maybe another dozen configurations.... :-)

Code cleanup/bug fix
Description:
Hoist function call out of inner loop of type conversion by retrieving
source & destination precisions once, outside the loop.
There's still some overhead because this information is stored in
variables set at run-time, when it's really constant for the particular
machine. Further work to set compiler macros would allow this code to be
optimized better by the compiler with dead code removal. We'll continue
to work on this area...
Also, made new internal H5T_compiler_conv routine static instead of of
private, until we need to reference it from another source code module.

Description: H5T_register() replaces any existing data conversion path
with a new path.
Solution: Added a parameter to H5T_register() and H5T_path_find() to
signal the library whether the new conversion path is from API function
H5Tregister() or from private function like H5T_init_interface(). If it
is from H5Tregister(), replace existing path. If it's from H5T_init_interface()
and the library is trying to register default hard conversion functions,
don't replace existing path because the path is registered by the library.
For example, the library registered H5T_conv_int_float() and is trying to
register H5T_conv_long_float(). The size of long is equal to int. There's
no need to replace the path H5T_conv_int_float().

Description: Quincey added the condition branch (else if (*((ST*)S) != (ST)((DT)(*((ST*)S)))))
in the definition of the macro H5T_CONV_Fx_CORE. It handles a special situation
when the source is "float" and assigned the value of "INT_MAX". Compilers do roundup
making this value "INT_MAX+1". This branch is to check that situation and return
exception for some compilers, mainly GCC.
The branch if (*((ST*)S) > (DT)(D_MAX) || (S_PREC < D_PREC && *((ST*)S) ==
(DT)(D_MAX))) is for some compilers like Sun, HP, IBM, and SGI where under
the same situation the "int" doesn't overflow.
A test was added to dt_arith.c to check 2 conversions, from float to int where the
float is INT_MAX, and from double to signed char where the double is SCHAR_MAX.
Platforms tested: h5committest and fuss.

Bug fix & code cleanup
Description:
Fix problem with detecting precision overflows in a more portable way.
(I was depending on the compiler not removing some temporary variables, which
was a bad bet... :-)
Also, hoist the checking for the exception handling routine out of the
inner conversion loop, which should speed up conversions which don't have an
exception handling routine defined.

LDOUBLE_LLONG) to the H5T_CONV_INTERIM_SOURCE_DESTINATION style (like
H5T_CONV_INTERIM_FP_FP OR H5T_CONV_INTERIM_LDOUBLE_LLONG), to be more

Description: Added 2 new configure options, --enable-exception and --enable-accuracy.
--enable-exception lets the library check whether user's exception handling
functions are present during compiler data conversions and use them if they are.
When it's disabled, this step is skipped to improve conversion speed. This
step isn't implemented yet for soft conversions because there would be little
gain in speed.
--enable-accuracy guarantees data accuracy during data conversions. It means
the library will choose compiler conversions only if the accurate data is
secured. Otherwise, the library will go for the library's own conversions. If
this option is disabled, the library uses compiler conversions in favor of
their speed as long as they work even if data can be incorrect.
Platforms tested: h5committest and fuss. Some systems may fail after this
checkin.

Description:

It handles a special situation when the source is "float" and assigned the value
of "INT_MAX". A compiler may do roundup making this value "INT_MAX+1". However,
when do comparison "if (*((ST*)S) > (DT)(D_MAX))", the compiler may consider them
equal.

of floating-point type is filled up with 8 special values, +/-0, +/-infinity,
+/-QNaN, +/-SNaN.
Also added 3 new conversion exception values H5T_CONV_EXCEPT_PINF, H5T_CONV_EXCEPT_NINF,
H5T_CONV_EXCEPT_NAN, for floating-point special values positive infinity, negative
infinity, and NaN. These values are for conversion exception callback function defined
