RFC: Any reason not to do this?

[Martin Mathieson <martin.r.mathieson () googlemail com>]

In a profile, I was surprised to see that > 2.5% of time was spent calling
dissect_sip_tcp_heur().  There are no SIP PDUs in the log.  HTTP was very
similar.

Does the attached change look reasonable?  It does a quick check for the
first character being printable before trying to extract the first line and
check it for NULL characters.

Thanks,
Martin
