[svn-r17713] Add the following patch

===
The following patch to h5copy.c on or near line 173 makes the
tool substantially more useful...
     *flag = (*flag) | fla;
Because the command-line option parsing permits multiple '-f' arguments,
this will have the effect of or'ing the flags together so one can do
someting like....

~/tmp/hdf5-1.8.1/tools/h5copy/h5copy -i multi_ucd3d.h5 -s block5 -o gorfo -d foo
 -f shallow -f soft

Also fixed to exit failure if no command option is given.
