Bug fixes and code cleanup
Description:
Lots of changes here:
- Fixed bug #691 - when shared datatypes are used in attributes they
are incorrectly copied into the attribute instead of referring
the the named datatype in the file. This required bumping the
version of the attribute message. The new version of the attribute
message is only written out when a shared datatype is used in
the attribute. [Also, this format change made the size of the
attribute smaller.]
- Added information to attribute debugging routine so that shared
datatypes are displayed correctly with the h5debug tool.
- Refactored the H5O* routines to extract code that was common to
several routines into subroutines to call.
- Added 'link' method for H5O message sub-classes, which increments
the link count on shared objects when a message is created which
shares them.
- Corrected [unreported] bug where the link count was not being
decremented on the shared object when a object header message
with a reference to that object was deleted from the file.
- Reduced size of shared message from 49 bytes (which was incorrect
anyway and should have been 48 bytes) to 10 bytes, which required
bumping the version of "shared" messages.
- Refactored some of the shared datatype routines to allow for easier
queries of "committedness" internally to the library and also
added routine to easily increment/decrement the reference count of
a shared datatype.

Bug fix
Description:
The MPI_File_set_size() routine on ASCI Red is not able to extend files
so that they are larger than 2GB.
Solution:
Add an extra macro which controls whether MPI_File_set_size() can handle
>2GB offsets or if our "older" way of reading a byte, then writing a byte at
the appropriate offset should be used.

Code cleanup, etc.
Description:
Generalize Ray's datatype fixes to handle packing compound datatypes which
are the base type of an array or variable-length type, etc.
Also track "packedness" of a compound datatype from it's creation, instead
of only setting the 'packed' flag after the datatype was explicitly packed.
Updated docs to reflect that a compound datatype is allowed to grow (but
not shrink).

Bug fix.
Description:
Correct bug where a file opened twice, once with read-write permission
and once with read-only permission would cause closing the file with the
read-only file ID to fail because it was trying to flush information out
of the file.
Solution:
Check the permissions on file IDs that are being closed and only flush
when the particular file ID was opened with write permission.

Misc. update:
Bug fix
Description:
The VFL driver ID in a file's access proprty list wasn't being reference
counted correctly, causing the VFL driver to get prematurely closed after
several calls to "H5Pget_access_plist->H5Pclose".
Solution:
Increment VFL driver ID reference count when copy of file's access property
list is made in H5Pget_access_plist()

Bug Fix and code cleanup
Description:
Correct error in H5T_detect_class that was causing nested compound datatypes
with to not detect the datatype class of fields correctly, which caused errors
with fill-values, variable-length datatypes and chunks later on.
Return the rank of the array datatype from H5Tget_array_dims(), like
H5Sget_dims().
Lots of cleanups to datatype code, to make the handling of arrays, compound
types, variable-length strings and sequences and enumerated types more
consistent and robust.

Bug fix
Description:
When datasets are deleted from a file, they are removed from the sieve
buffer, but instead of invalidating only the part of the sieve buffer affected,
the sieve buffer code would throw away the entire sieve buffer, potentially
including other raw data in the buffer that hadn't been written to disk yet.
Solution:
Improve the sieve buffer clearing code to handle partial invalidations.

Bug fix
Description:
H5Gget_objname_by_idx should allow NULL for the 'name' parameter, to allow
for querying for the name's length.
Solution:
Allow NULL for the 'name' parameter, the internal functions were already
ready to handle that case.
Clean up RM information about H5Gget_objname_by_idx and
H5Gget_objtype_by_idx also.

Bug fix
Description:
H5Gget_num_objs, H5Gget_objname_by_idx and H5Gget_objtype_by_idx were
only accepting a group ID, instead of a location ID, as our documentation for
them stated.
Solution:
Allow them to accept a location ID.

Bug fix
Description:
I/O on chunked datasets with a scalar dataspace for the memory dataspace
was not working correctly.
Solution:

of dimensions of the file's dataspace) dataspace of dimensions 1x1x1...

Bug fix
Description:
Linking and unlinking objects with multiple internal and/or trailing '/'s
was not handled well in the library.
Solution:
"Normalize" strings by removing trailing '/'s and collapsing multiple
internal '/'s down into just one '/' before operating on the name.

I/O on chunked datasets with point selections was not working correctly.
Solution:

Bug fix
Description:
When a non-default indexed storage B-tree internal 'K' value is set by the
user, the chunked datasets created in that file (until it is closed) use the
user's 'K' value and the data can be accessed correctly, but the 'K' value is
not stored in the file.
However, once the file is closed and re-opened, the non-default 'K' value
is lost and the data in the chunked datasets will not be able to be accessed
correctly.
Solution:
Store the indexed storage B-tree internal 'K' value in the superblock.
