[svn-r20885] Description:

    Bring Coverity changes back to trunk:

r20340:
Address coverity issue 248.  Set freed pointer to NULL if realloc fails, then check for NULL before attempting to close array of handles stored in memory addressed by pointer.

r20341:
Added initialization udata.path = NULL; udata.visited = NULL; to prevent unintialized use after done: label.

Do C-style initialization AFTER all variable definitions.

r20342:
Fix valgrind error in H5DUMP-XML-tall.h5

r20343:
Addressed Coverity issue 591 - check the return value of H5S_SELECT_ITER_RELEASE.

r20344:
Added initialization udata.path = NULL; to prevent uninitialized used after done: label

r20347:
Purpose: Fix memory leak in overhead.c

Description: Fixed leak in test() in overhead.c where array "had" was never
freed.


r20348:
Addressed Coverity issue 705 - added prototype for resize_configs_are_equal to cache_common.h.

r20392:
Purpose: Fix coverity issues 1677 and 1678

Description: Added return value checking for 4 funciton calls in
H5tools_get_symlink_info().

r20394:
Purpose: Fix coverity issues 1674 and 1675

Description: Modified H5Epush2() and H5E_printf_stack() to keep track of whether
va_start() has been called, and to call va_end() at the end if so.

r20395:
Should be H5MM_calloc(count * sizeof(void*)). Fixed --gh 

r20396:
Should be H5MM_calloc(count * sizeof(void*)). Fixed. --gh

Tested on:
    Mac OSX/32 10.6.7 (amazon) w/debug & production
