Hello.

I read packet header and try to read string length and string data. But
string length field has illegal value. I add expert info. But how to
stop dissection after adding expert info? I can not dissect rest of
packet at this point. I can return error code from this function, but
calling tree may be too big. May be exists more graceful solution?
Something like exceptions in C++.

PS. I found DISSECTOR_VERIFY_DATA in mailing lists, but it is not
implemented in source code.
