Dmitry Bogatov 36b5f4da53 Check if input to dc_send_text_msg is valid utf8 ...

With this change, passing invalid utf8 string to `dc_send_text_msg' does not
crash application, it prints warning and returns error code.

It should be admitted that this fix is sub-optimal: if input C string is valid
utf8 (which is likely), result of successful conversion to `&str' is discarded
in `dc_send_text_msg', and the same input C string is converted again with
`as_str' in `prepare_msg_raw'.

It is not clear how to fix it in non-disruptive way, since input C string is
passed down to call stack as part of `dc_msg_t' struct, which is part of C ABI.
