Commit metadata tagging framework.
Description:
This check-in contains a new framework whose goal is to apply
a tag value to each new entry in the metadata cache as it is created.
This tag value is such that it relates each piece of metadata to the
HDF5 object that it belongs to (dataset, group, et cetera).
This changeset includes the framework that applies the tags as
well as a suite of tests to verify correct tag application, though does
not yet make use of the tag values to flush/evict individual objects.
Please refer to the "flush/evict individual objects" RFC for further
discussion of these changes.

Correct Coverity issue #1 by removing dead code
r18077:
Fix coverity item 142. When an error occurred while copying a linked list in
H5S_point_copy, the library would not free the partially allocated list. Added
code to free the list in this case.

r18082:
Fixed coverity issues 321 and 316.
321: freed sm_buf in error handling to remove resource leak.
Also set sm_buf to NULL after other instances in which
it is freed to prevent double free.
316: initialized nmembs to 0.
r18083:
Correct Coverity issue #6 by removing debugging knob from error reporting code.
r18084:
Fix coverity item 269 + others. When a error occurred in a function using the
h5tools error framework, the "past_catch" variable would not be set to true
because that statement was before the label that goto jumped to. This could
cause a failure in the cleanup section to go back to the start of the section,
freeing variables twice, etc.
Moved the label infront of past_catch=TRUE.
r18085:
fixed coverity #27, check if (heap) before use heap->obj....

Description:
H5HG_load made improper assumptions about the ordering of object indices, namely
that they are in order. Not only is this not guaranteed by the file format
spec, but this condition can be violated if id's "wrap around" which can happen
when overwriting VL data. H5HG_load has been fixed to handle any order of
indices. Also fixed some other bugs involving allocation of global heaps in
memory.

Add 'notify' callback to metadata cache clients, so that they can be

from the cache.

Tested platform:
Kagiso only since it is only a comment block change. If it works in one
machine, it should work in all, I hope. Still need to check the parallel
build on copper.
This feature is still in progress; Shared Object Header Messages are not
complete as a feature and are not thoroughly tested. There are still
"TODO" comments in the code (comments with the word "JAMES" in them,
so as not to be confused with other TODO comments).
Hopefully this checkin will reduce the liklihood of conflicts as I finish
implementing this feature.
All current tests pass on juniper, copper (parallel), heping, kagiso, and mir.
handle flush callbacks which can dirty other entries, and
resize and/or rename the target entry.
This feature is needed by the fractal heap code.
Also added associated test code.
H5Commit tested. Test failed on heping, but the
error appears to be a syntax error in an un-related
file.
Tests on copper & sol passed, along with tests on
phoenix.

Interim checkin of code changes moving management of the is_dirty flag
into the cache code.
Description:
Prior to this checkin, management of the is_dirty flag was handled
above the level of the metadata cache. This can no longer be allowed,
as it introduces a race condition in the proposed fix for a cache
coherency bug in PHDF5.
Solution:
Move management fo the is_dirty flag to the cache code proper.
Entries are now marked as dirty via a flag on the unprotect call.

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
Misc. update:
1) Provide facilities in cache to allow us to avoid a potential cache
consistency bug in the parallel case.
2) Clean up a off by one sanity checking bug.
3) Turn off execution of long running tests in debug mode.
Description:
1) In the parallel case, all writes to metadata must be collective,
but reads may not be. In pricipal, this allows us to different
contents in different caches. This isn't a problem as long as the
correct data is always on disk, but unless we can force certain
writes immediately, that need not be the case.
2) & 3) should need no further explanation.
Solution:
1) Add code allowing us to mark cache entries, and then force
these entries to be flushed at a later time.
Note that to actually avoid the bug, we will have to modify
existing code to use these new features.
2) & 3) should need no further explanation.
Platforms tested:

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".

Code cleanup, sorta
Description:
Added ifdef sections for "H5_USING_PURIFY" in various places in the code,
which are designed to reduce the spurious "uninitialized memory read" warnings
from purify which are actually OK. Note that this macro will have to be
turned on by adding it to the CFLAGS for the build - I didn't think it was
important enough to add a configure flag for.
Also, the changes in H5HG.c optimize the walks through the objects in a
heap to only look at the 'used' entries instead of all the 'allocated' entries.

Bug Fix
Description:
If an HDF5 file grows larger than its address space, it dies and is unable to
write any data. This is more likely to happen since users are able to change
the number of bytes used to store addresses in the file.
Solution:
HDF5 now throws an error instead of dying. In addition, it "reserves" address
space for the local heap and for object headers (which do not allocate space
immediately). This ensures that after the error occurs, there is enough address
space left to flush the entire file to disk, so no data is lost.

Also clean up some warnings with gcc 3.4.x
Platforms tested:
FreeBSD 4.10 (sleipnir)
Too minor to require h5committest
Description:
Replaced the old metadata cache with a cache with a modified LRU
replacement policy. This should improve the hit rate.
Solution:
Since we want to flush cache entries in increasing address order, I
used the threaded binary B-tree code to store the cache entries.
There is a fair bit of overhead here, so we may want to consider
other options.
While the code is designed to allow the support of other replacement
algorithms, at present, only a modified version of LRU is supported.
The modified LRU algorithm requires that a user selectable portion
of the cache entries be clean. The clean entries are evicted first
when writes are not permitted. If the pool of clean entries is used
up, the cache grows beyond its user specified maximum size. The
cache can also exceed its maximum size if the combined size of the
protected (or locked) entries exceeds the maximum size of the cache.
Platforms tested:
eirene (serial, parallel, fp), h5committested
Misc. update:
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.
Platforms tested:
FreeBSD 4.10 (sleipnir) w/gcc34
h5committest
Code optimizations
Description:
Eliminate memset() call in H5S_set_extent_simple().
Use malloc() instead of calloc in H5B<mumble>.
Change global heap code to track heap objects that are in use in order to
allocate new objects more quickly and also to avoid memset() and calloc() calls.
Platforms tested:
Solaris 2.7 (arabica)
FreeBSD 4.10 (sleipnir) w/parallel
Too minor to require h5committest
Code optimization
Description:
Allow global heap collections to grow in size (up to a 64K limit) if they
are able to. This allows them to grow to a more reasonable size than the 4K
minimum size.
Platforms tested:
Solaris 2.7 (arabica)
FreeBSD 4.10 (sleipnir) w/parallel
Too minor to require h5committest
Code optimization
Description:
Call malloc() instead of calloc() for data structure that we completely
initialize.
Platforms tested:
Solaris 2.7 (arabica)
FreeBSD 4.10 (sleipnir) w/parallel
Code optimization
Description:
Move handling for free list arrays that have no maximum size to separate
set of routines and optimize computations for free list arrays with maximum
size to avoid re-computing sizes all the time.
Platforms tested:
h5committest
Solaris 2.7 (arabica)
Bug fixes & code cleanup
Description:
Back out some of the debugging that was inadvertently checked in recently.
Platforms tested:
FreeBSD 4.9 (sleipnir)
too minor to require h5committest
Code cleanup
Description:
Clean up compiler warnings, especially the 'FUNC' variable not used which
comes out in production mode.
Solution:
Had to add a new FUNC_ENTER_NOAPI_NOINIT_NOFUNC macro for those non-API
functions which don't need the 'FUNC' variable defined. (This will be _so_
much easier when C99 is standard on all our supposed platforms, since it has a
__FUNC__ macro... )
Platforms tested:
FreeBSD 4.9 (sleipnir)
too minor for h5committest (although there were lots of files changed, the
change was minor in each one)
