DESCRIPTION
Chop off trailing blanks off of a Fortran string and
move it into a newly allocated C string. It is up
to the user to free this string.

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.
