1023374492 [svn-r27768] Description:
Complete revamp of package initialization/shutdown mechanism in the library.
Each package now has a single init/term routine.

    This new way should avoid packages being re-initialized during library
shutdown and is also be _much_ more proactive about giving feedback for
resource leaks internal to the library.

    Introduces a new "module" header file for packages in the library
(e.g src/H5Fmodule.h) which sets up some necessary package configuration macros
for the FUNC_ENTER/LEAVE macros.  (The VFL drivers have their own slightly
modified version of this header, src/H5FDdrvr_module.h)

    Also cleaned up a bunch of resources leaks all across the library and tests,
along with addressing many warnings, as I encountered them.

Tested on:
    MacOSX/64 10.10.5 (amazon) w/serial & parallel
    Linux/64 3.10.x (kituo) w/serial & parallel
    Linux/64 2.6.x (ostrich) w/serial

1e36b5a348 [svn-r24726] Description:
Revert some earlier usage of strncpy, which was incorrect.

    Bring Coverity changes from branch back to trunk:

r20821:
    Use HDstrncpy. --gh
    (Fixed already, with strdup)

r20822:
    (Not merged, incorrect use of HDstrncpy())

r20823:
    (Not merged, incorrect use of HDstrncpy())

r20824:
    Maintenance: Bug fix: addressed CID 666.
    Value stored at *expression_len should be used in the call to
        HD5packFstring to avoid overflow (and unnecessary arithmetic
        calculation and casting) 

r20825:
    Issue 642: Added check for error and handler with print to stderr and exit.

r20826:
    Undo revision 20818, as that issue has already been fixed in the 1.8 branch
        and trunk (but not coverity branch)

r20827:
    (Not merged, incorrect use of HDstrncpy())
    
r20828:
    Use HDstrncpy. --gh
    (Corrected use of strncpy())

r20829:
    Check return of H5Lget_val(print_udata->fid, path, targbuf,
        linfo->u.val_size + 1, H5P_DEFAULT) and if error set trgbuf[0] to 0.
        Check if  H5Lunpack_elink_val(targbuf, linfo->u.val_size, NULL,
        &filename, &objname) was successful and allow print. Otherwise filename
        and objname are not created. (init those to NULL)

r20830:
    resolved coverity issues 939, 940, 941, 944, and 947.

    all were complaints about use of sprintf, and in all cases, the
    buffers used were large enough for all eventualities.

    Resolved issue by replacing calls to sprintf with calls
    to snprintf.

r20831:
    Maintenance: Addressed CID 852
    Replaced sprintf with snprintf

r20832:
    Purpose: Fix valgrind issues with hl/examples/ex_image2

    Description:
    Modified hl/examples/ex_image2 to free global "gbuf" before exit.

cad9846d77 [svn-r13926] Description:
Add small interface to "wrap" a static buffer (usually on the stack), but
still allow for buffers larger than the static buffer to be allocated.  This
can eliminate _many_ short-lived buffer allocations in situations where the
buffer is a predictable size (or at least a "very likely" size).

    Also, some minor code cleanups, particularly in the SOHM caching code.

49d1901fdd [svn-r12592] Description:
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.

Solution:
    There's too many changes to really describe them all, but some of them
include:
    - Stop abusing the H5G_entry_t structure and split it into two separate
        structures for non-symbol table node use within the library: H5O_loc_t
        for object locations in a file and H5G_name_t to store the path to
        an opened object.  H5G_entry_t is now only used for storing symbol
        table entries on disk.

    - Retire H5G_namei() in favor of a more general mechanism for traversing
        group paths and issuing callbacks on objects located.  This gets us out
        of the business of hacking H5G_namei() for new features, generally.

    - Revised H5O* routines to take a H5O_loc_t instead of H5G_entry_t

    - Lots more...
