[svn-r15804] Purpose: Add option to h5ls to enable external link traversal.
Description: Added -E option to h5ls. When set, this alows h5ls to enter external files (currently only through an external link). The -r option by itself will no longer allow h5ls to traverse external links. Tested: kagiso, linew, smirom (h5committest)
