Fix off-by-one error in computing the size of metadata prefixes for v2
B-tree internal & leaf nodes.
General code cleanup and reformating.

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)

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.

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.

Switch to somewhat less high performance checksum implementation that
doesn't run into problems for mis-aligned buffers in memory.

Break out a bunch of the misc. routines that were in src/H5.c into more
specific modules.
Add optimized fletcher32 checksum routine, for checksumming metadata as
well as raw data.

Change call from H5O_loc_free() to H5G_name_free() when certain dataset
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.

Correct bug in doubling table algorithm which was generating incorrect
row & column for offset larger than could be represented in 32 bits.
Also, beef up the error checking in direct block code a bit

Fix bug in deserializing sections from disk which would recompute the
sections' serialized size while the sections were being deserialized,
thoroughly baffling the algorithm.

- 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
entries into the metadata cache directly, instead of insterting them,
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)

Clean up some of the parallel chunk I/O compiler warnings and other minor
code rearrangement.
Tested on:

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.

Revert passing the v2 B-tree class to callbacks, it turns out to be
unnecessary. Also revert have a "class private" pointer for each v2 B-tree
class.
Add in support for the different flavors of fractal heap 'huge' objects
also.

upgrade.
Description:
Changed the error report of read and write to HSYS_GOTO_ERROR to report
system error messages.
Platforms tested:
heping, osage, copper.
-O3 flag causes compilation problems on most of the platforms with Intel compiler.
The problem exists in all vesrions of icc compiler up to the newest 9.1
Solution:
Use less agressive default setting O2 to avoid headache
Platforms tested: Linux 2.6 ia64 at UCAR (hal), cobalt (NCSA)
Maintenance for alpha5 release; brought command files up-to-date.
Platforms tested:
VMS server. Compilation, C++, F90 and tools tests passed;
C tests are still running.
Allow the heap ID length to be chosen at heap creation time, to allow
for making heap IDs long enough to directly embed the file offset & length
of 'huge' objects in the heap ID (which allows them to be retrieved directly
from disk, instead of requiring them to be looked up in the B-tree that tracks
'huge' objects)
Tested on:
FreeBSD/32 4.11 (sleipnir)
Linux/64 2.4 (mir)
Solaris/64 9 (shanti)
Clean up a couple of compiler warnings in the 'huge' object code in the

module.

Fix failure in "remove bogus ID" test which turned up randomly (due to
random "bogus" IDs being used in test :-) by adding some more defensive
checks on object IDs to the object removal code.
