Patch to add error expert info if HTTP payload is more than content-length
header value

Build Information:
I have downloaded wireshark-1.8.2 sources, since that is the version on my
Ubuntu (13.04).

--
If HTTP response contains "Content-Length: x" but the payload is actually more
than x bytes, then we use the lower (header) value.

At this time, we can add a "malformed-packet" error expert info.

This is useful because ADCs (application load balancers) stop tracking such
connections because the server is sending more than what it advertised.  A
trace loaded on Wireshark with this change will show any such malformed
responses.
