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
move it into a newly allocated C string. It is up
to the user to free this string.

SUCCEED / FAIL
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.
