Changed functionality of H5Pget_data_transform
Description:
H5Pget_data_transform no longer allocates memory for the transform string...it
is the user's responsbility to do so.
Solution:
Made H5Pget_data_transform be more in line with other functions that do
similiar things:
User now has to allocate memory for the string themselves and specify how much
of the string should be copied into the buffer. There is also support for
querying the length of the transform string.

Bug fix.
Description:
The previous H5_ULLONG_TO_FP_CAST_WORKS fix does not quite work
since the problem was an error during compiling while the fix
was trying to check for the error condition during runtime.
The MS-Compiler still complains about not supporting ULLONG
to Float.
Solution:
A temperary patch is to have two #define of H5Z_XFORM_TYPE_OP
according to if H5_ULLONG_TO_FP_CAST_WORKS is defined. This
works but a better solution is needed.
Platforms tested:
Windows (by Kent) and heping (Linux by me).

Description: "char" was considered as always "signed char" in data type conversion. However, ISO C leaves
the definition of "char" to individual implementation. i.e. for IBM AIX C compiler, it's treated as "unsigned
char".
Solution: Changed all "char" to "signed char". Don't even do "char" anymore because its definition is up
to each vendor.

Code refactor
Changed functionality of H5Pget_data_transform
Description:
Rewrote much of H5Ztrans.c to use macros, which cut down on the amount of code
significantly.
H5Pget_data_transform now allocates memory for the data transform string,
copies the string into this memory, and
returns this pointer to the user, instead of returning a pointer to the
internal transform string stored by hdf. It is the user's responsibility to free
this memory when they are done with it.

Bug fix
Description:
Fix typo in #ifdef for unsigned long long to double conversion.
Changed WIN32 check to H5_ULLONG_TO_FP_CAST_WORKS
This check-in (and the one before it) also includes a large code-refactoring
that is still in progress.
Solution:
the ifdef for the plus case was checking unsigned long instead of unsigned
long long. Moved the check to the right location.

Purpose:
Feature
Description:
Datatypes and groups now use H5FO "file object" code that was previously
only used by datasets. These objects will hold a file open if the file
is closed but they have not yet been closed. If these objects are unlinked
then relinked, they will not be destroyed. If they are opened twice (even
by two different names), both IDs will "see" changes made to the object
using the other ID.
When an object is opened using two different names (e.g., if a dataset was
opened under one name, then mounted and opened under its new name), calling
H5Iget_name() on a given hid_t will return the name used to open that hid_t,
not the current name of the object (this is a feature, and a change from the
previous behavior of datasets).
Solution:
Used H5FO code that was already in place for datasets. Broke H5D_t's, H5T_t's,
and H5G_t's into a "shared" struct and a private struct. The shared structs
(H5D_shared_t, etc.) hold the object's information and are used by all IDs
that point to a given object in the file. The private structs are pointed
to by the hid_t and contain the object's group entry information (including its
name) and a pointer to the shared struct for that object.
This changed the naming of structs throughout the library (e.g., datatype->size
is now datatype->shared->size). I added an updated H5Tinit.c to windows.zip.

Code optimization
Description:
Avoid performing a check on the number of objects in a group (which
currently involves iterating over all entries in the group's B-tree) before
calling H5G_get_obj<foo>_by_idx. Instead, just have H5G_get_obj<foo>_by_idx()
notice when you've walked off the end and return fail then.

Bug fix.
Description:
Code would attempt to Calloc with zero count when a simple expression
that has no x term. That resulted in NULL for some platform (like AIX).
That appeared as a failure treated as out of space.
Solution:
Checked if count is larger than 0 before making the calloc request.
Platforms tested:
Tested in copper (pp) where the failure appeared. Also in eirene
as double check. No h5committest as the change is trivial.

Port fix of parallel I/O mode confusion bug from the 1.6 tree to the 1.7 tree.
Description:
Collective I/O is not supported for point selections. Thus when some
processes attempted I/O with point selections, and others without, some
attempted collective I/O while others did independent I/O.
Solution:
Arranged for all processes to compare notes before starting I/O, and
for all to use independent I/O if any one of them can't do collective
I/O.

Added H5Pget_data_transform
Added support for polynomial data transforms
Description:
There is now support for polynomial data transforms (ie, (2+x)*(x-5)) instead
of just linear ones.
Note that, in order to compute a polynomial transform, one temporary copy of
the original data must be stored for each occurence of "x" in the transform
expression. This can result in very high memory usage for expressions of high
order.

Code cleanup
Description:
Tweak recent "forward compatibility" changes to the H5E* API (which allowed
for the old H5E API functions to remain unchanged) by allowing for the error
stack callback function (H5E_auto_t) to also remain unchanged from the 1.6
branch. This required changing the H5E{get|set}_auto routines to have the
old style H5E_auto_t type (which didn't have a stack ID parameter) and the new
H5E{get|set}_auto_stack routines to have a newer "H5E_auto_stack_t" type (which
has a stack ID parameter). This should make the H5E API changes as forwardly
compatible as possible.
One side-affect of this change was that it was impossible to determine if
the current auto error callback was the old style (H5E_auto_t) or the new style
(H5E_auto_stack_t) of callback, so a new API function (H5Eauto_is_stack) was
adde to query this.

the Crays and other machines (the heap ID is always encoded as an int32 anyway)
