USAGE
   int HD5c2fstr(str, len)

RETURNS
   SUCCEED
DESCRIPTION
   Change a C string (NULL terminated) into a Fortran string.
   Basically, all that is done is that the NULL is ripped out
   and the string is padded with spaces

   Chop off trailing blanks off of a Fortran string and

DESCRIPTION
   given a NULL terminated C string 'src' convert it to
   a space padded Fortran string 'dest' of length 'len'

   This is very similar to HDc2fstr except that function does
   it in place and this one copies.  We should probably only
   support one of these.
