[svn-r10829] Purpose:

Bug fix

Description:
Various system or software (e.g. MPE) will print some diagnosis
messages to stderr that cannot be suppressed.  They messed up
the output matching. Installed the STDERR_FILTER() to remove
all these messages.

Platforms tested:
LANL flash.

Misc. update:

tools/h5diff/testh5diff.sh
