Good news!, now I don't need to use tainted module anymore.

Thanks Eddie.

> * Click's annotation system has been updated to allow named annotations and
> runtime-specified annotation offsets.  For example:
>
>     AnnotationInfo(PAINT2 17 1);   // define a 1-byte "PAINT2" annotation
>                                    // at annotation byte 17
>     AnnotationInfo(CHECK_OVERLAP PAINT PAINT2 DST_IP);
>                 // check that the named annotations don't overlap
>
>     ... -> Paint(2) -> ...                     // sets PAINT anno to 2
>     ... -> Paint(ANNO PAINT, COLOR 2) -> ...   // also sets PAINT anno to 2
>     ... -> Paint(ANNO PAINT2, COLOR 10) -> ... // sets PAINT2 anno to 10
>
> See the Paint family for some examples of how this is used.
>
> As part of this change, the Packet::user_anno() functions have been deprecated
> in favor of new Packet::anno() functions.  The new versions take byte offset
> arguments uniformly.
