Remove some references to "twig" and "branch" internal B-tree nodes, which
were eliminated in the previous checkin.
Tested on:

Enable the checksums on the free space tracker's metadata.
Clean up a few compiler warnings from 64-bit machines.

Improve density of the B-tree further. For greater depths of B-trees,
the gains are over 100%...
Also, don't split internal nodes with 3->4 splits, use a 1->2 split
instead, so that the density of the nodes around a split is maximized.

Description:
Update copyright notice, after assignment of the HDF products to THG.
Adds "Copyright 2006 by The HDF Group (THG)."
Provides separate credits to the U of I for 'NCSA HF5' and
to THG for 'HDF5'.
Testing:
Visual inspection.
Split edge nodes in the tree with a 1->2 node split, instead of a 2->3 node
split, which creates a more dense tree when a pattern of record insertions
occurs (because it leaves behind full nodes instead of 2/3 full nodes).
Tested:
FreeBSD/32 4.11 (sleipnir)
Linux/64 2.4 (mir)
Linux/32 2.4 (heping)
Solaris/64 2.9 (shanti)
Improve default settings.
Use mpicc, mpif90, mpirun as the default $CC, $FC, and $RUNPARALLEL if
enable-parallel.
Tested:
in TG-NCSA both serial and parallel.
Code cleanup.
Description:
Removed argc and argv from the function arguments of h5tools_get_fapl() and
h5tools_fopen(). They were used to call MPI_Init() which was no longer
needed.
Tested:
heping (serial and parallel).
Thread safe error test fails due to the changes in the error stack.
Solution:
Updated the expected error stack.
Platforms tested:
heping (too minor, probably will fail on Tuesday anyway)
Refactor the file storage of "twig" nodes in the B-tree to allow them to
store more records, increasing the average density of the B-tree 30-40%.
Increase # of records in "insert lots" regression test to still create
B-tree of depth 4
Update h5debug to interpret difference of 'branch' and 'twig' internal
nodes in B-tree correctly.

Re-order the fheap & btree2 tests so that the btree2 test runs first,
because the fractal heaps use v2 B-trees for tracking huge objects.

These errors should be investigated more thoroughly later. The underlying
problem in links.c seems to be that files opened multiple times don't share
the same H5F_shared_t struct. Perhaps identifying when this is the case
would be helpful?
Tested on mir.
Fix off-by-one error in computing the size of metadata prefixes for v2
B-tree internal & leaf nodes.
General code cleanup and reformating.
Tested On:
Mac OS X.4/PPC (amazon)
Too minor to require h5committest
Provide more abstract internal routine for computing checksums on metadata
in a file. This will allow a unified policy on which algorithm to choose and
under what criteria (length probably) to be more easily maintained.
Tested On:
Linux/32 2.6 (chicago)
Linux/64 2.6 (chicago2)
Add support for checksumming fractal heaps. This is always enabled for
the heap header and indirect blocks (as they are "pure" metadata) and is
optional for direct blocks, since they may be used for "raw" data.
Also, rearrange direct block routines in H5HFcache.c to be in a more
sensible location in the file. (probably should have been a separate checkin,
since the diffs are mostly useless for this checkin... *sigh*)
Tested on:
Linux/32 2.6 (chicago)
Linux/64 2.6 (chicago2)
Comment out the use of the "-Wpadded" flag, it's generating far too many
warnings that are impossible to correct and probably making it harder to see
other warnings that are more important.
Tested on:
Linux/32 2.6 (chicago)
Linux/64 2.6 (chicago2)
Since these examples need to follow filesystem paths, the Makefiles need
to create directories in the examples directory; added this to the
Makefile.am.
Tested on Windows, mir, juniper
Tweak the library's new faster fletcher32 algorithm to always produce the
same checksum as the previous fletcher32 code in the fletcher32 I/O pipeline
filter and switch the filter to use the library's version of the algorithm.

well as raw data.

open failures are generated.

Add a bunch more regression tests:
- Verify opening a fractal heap more than once works correctly
- Check that 0 & 1-sized object insertions are handled correctly
- Check that bad heap IDs are detected when attempting to read an
object
- Check that doubling tables with different parameter values are
working correctly
Add some more checks to the code to detect 0-sized object insertions and
bad heap IDs for reading.

- Migrate "direct block location" routine from H5HFman.c to H5HFdblock.c,
which is a more appropriate location
- Optimize performance of heap code by taking advantage of pinned
indirect blocks and use them without putting a metadata cache
protect/unprotect pair around them.
- Other minor compiler warning cleanups and optimizations...

Take advantage of the new feature in the metadata cache to insert pinned

protecting them, pinning them and unprotecting them.

Object header locations (H5O_loc_t's) can now "hold open" a file and
decrement its open object count when they close. This means that
locations (H5O_loc_t's and H5G_loc_t's) should always be freed.
Added more thorough tests to ensure that external files are closed.
flag, and pin an entry as it is inserted.
The objective is to avoid some function call overhead in fheap.
Also added matching test code in test/cache.c & test/cache_common.c
(also testpar/t_cache.c checked in separately by accident)
h5commit tested
Clean up some of the parallel chunk I/O compiler warnings and other minor
code rearrangement.
Tested on:
FreeBSD 4.11 (sleipnir) w/paralllel
h5committest
Several changes, all mooshed together:
- Add support for "tiny" objects - which can be stored in the heap
ID itself, instead of in the heap data blocks.
- Flesh out support for compressed direct blocks, but comment it
out until John's got some metadata cache changes in place to
support it.
- Add support for applying I/O pipeline filters to 'huge' objects
- Refactor 'huge' object code to store information for 'huge' objects
directly in the heap ID, when there are I/O pipeline filters
applied to the heap (and the heap ID is large enough to hold the
information)
- Update h5debug tool to correctly handle 'huge' & 'tiny' objects.
- Misc. other code cleanups, etc.
