Refactored free space manager to use metadata cache for serialized free
space sections. This speeds up the fractal heap test considerably...

Fix the last scattered bunch of problems with the object deletion code,
which appears to be completely working now (for objects that are stored
within heap blocks - standalone objects aren't implemented yet).
Also, re-work the regression test to speed up some of the existing tests
and add in 100-200 more combinations of tests - overall, its probably even
slower than it was... :-/

Checkpoint further work on object deletion code for fractal heaps. I
believe everything is finally working for this sub-task. More regression tests
soon, but I don't foresee any problems.

Code checkpoint
Description:
Add in more new features for the fractal heap code, mostly bringing in
more ability for deleting objects (which isn't completely working yet).
Also, checkpoint free space manager code, which is essentially complete
(although it needs some more work after the metadata cache has some additional
features)

Purpose:
Rename feature
Description:
Rename the "function stack" debugging feature to "call stack", so the H5FS*

Code cleanup
Description:
Added some comments about the thread-specific memory for the error and
function stacks.
Changed H5close() to not use the function stack (since it causes it to
be re-enabled after shutting it down)
Changed thread-safe semaphore code to not use dynamicly allocated memory.

Description: Compiler complained about const type * variables that were
used in the functions that require "non const" parameters.
Compilation failed.

New debugging feature
Description:
Add some code to track where memory from the internal free list allocator
is allocated within the library. It's not quite ready for "prime time" yet,
but it's close enough to be useful.
This is disabled by default and requires the H5FL_TRACK macro in
src/H5FLprivate.h to be uncommented to activate during debugging.

Code cleanup
Description:
Trim trailing whitespace, which is making 'diff'ing the two branches
difficult.
Solution:

sed 's/[[:blank:]]*$//' $f > sed.out && mv sed.out $f
end

Description: Removed PABLO from the source
Solution:
Platforms tested: arabica with 64-bit, copper with parallel,
heping with GNU C and C++ and PGI fortran (but
I disabled hl, there is some weird problem only
on heping: F9XMODFLAG is not
propagated to the Makefile files

Bug fix.
Description:
threadsafe test (ttsafe) would seg-fault if --disable-production --enable-debug
mode is used. Reason was that the fstack.nused field was not initialized
when created.
Solution:
Init new fstack.nused with 0.
Platforms tested:
Tested in mir, using development/debug mode.
Did not "h5committested" as change is trivial and limited to threadsafe mode.

Bug Fix/Code Cleanup/Doc Cleanup/Optimization/Branch Sync :-)
Description:
Generally speaking, this is the "signed->unsigned" change to selections.
However, in the process of merging code back, things got stickier and stickier
until I ended up doing a big "sync the two branches up" operation. So... I
brought back all the "infrastructure" fixes from the development branch to the
release branch (which I think were actually making some improvement in
performance) as well as fixed several bugs which had been fixed in one branch,
but not the other.
I've also tagged the repository before making this checkin with the label
"before_signed_unsigned_changes".
Platforms tested:
FreeBSD 4.10 (sleipnir) w/parallel & fphdf5
FreeBSD 4.10 (sleipnir) w/threadsafe
FreeBSD 4.10 (sleipnir) w/backward compatibility
Solaris 2.7 (arabica) w/"purify options"
Solaris 2.8 (sol) w/FORTRAN & C++

Code cleanup & minor optimization
Description:
Re-work the way interface initialization routines are specified in the
library to avoid the overhead of checking for them in routines where there is
no interface initialization routine. This cleans up warnings with gcc 3.4,
reduces the library binary size a bit (about 2-3%) and should speedup the
library's execution slightly.

Bug fix.
Description:
The new routines added for H5MM_[m|c]alloc were causing the function
stack code to infinitely recurse while allocating room for the thread-specific
information (when thread-safety was turned on).
Solution:
Call HDmalloc directly instead of H5MM_malloc

FreeBSD 4.9 (sleipnir)

New feature for developers.
Description:
Added "function stack" tracing to library. This allows developers (there
is no public API) to call H5FS_print within the library and get a listing
of the functions traversed to reach that point in the library. Eventually,
I may add support for reporting the parameters to each function also...
Mainly for debugging parallel I/O programs, but I think it will come in
handy in other cases also.
The function stack tracking is controlled with a configure switch:
--enable-funcstack, which defaults to enabled currently. When we branch
for 1.6, we should change the default setting on the branch to be disabled.
Also, added a destructor to the thread-specific keys when thread-safety is
turned on in the library. Otherwise, they were leaking memory and causing
difficult to debug errors in threaded programs (like the test/ttsafe test).
Platforms tested:
Tested h5committest {arabica (fortran), eirene (fortran, C++)
modi4 (parallel, fortran)}
FreeBSD 4.7 (sleipnir) w/thread-safety enabled.
Misc. update:
Updated MANIFEST with new files added (src/H5FS.c & src/H5FDprivate.h)
Update release_docs/RELEASE with thread-safety bug fix.
