unistr.h: declare u{8,16}_uctomb_aux for u{8,16}-chr

[Ralf Wildenhues]

The Intel compiler 9.0 gives these warnings on GNU/Linux:

| ../../gllib/unistr/u16-chr.c(39): warning #266: function declared implicitly
|       switch (u16_uctomb_aux (c, uc, 2))
| 
| ../../gllib/unistr/u8-chr.c(39): warning #266: function declared implicitly
|       switch (u8_uctomb_aux (c, uc, 6))

Similar for u{8,16}-strchr.c.

The difference to GCC here is that the __NO_INLINE__ test (whether the
compiler generally respects inline) gives false.

The patch below gets rid of the warning.  OK to apply?

Cheers,
Ralf

        * lib/unistr.h [GNULIB_UNISTR_U8_UCTOMB] (u8_uctomb_aux):
        Declare also if !HAVE_INLINE.
        [GNULIB_UNISTR_U16_UCTOMB] (u16_uctomb_aux): Likewise.
