[svn-r20385] Purpose:

Bug 2182 - h5ls and h5dump: update to use --enable-error-stack among tools, also update related descriptions

Description:
    Merged from HDF5 trunk r20378 and r20379
    Decided to use --enable-error-stack long option name only to 
    display error stack messages from HDF5 lib among tools.
    Updated to unify option name to '--enable-error-stack' for printing 
    HDF5 error stack messages for HDF5 tools. h5ls and h5dump for now.
    For h5ls, this replaces "-e/--errors" option, which is deprecated.
    For h5dump, remove -E from help page and RM , which was added by mistake
    before release1.8.7.
    Help page and RM got updated.
    Updated test case.
     
Tested:
 jam (linux32-LE), amani (linux64-LE), heiwa (linuxppc64-BE), tejeda (mac32-LE), linew (solaris-BE)
