1) Added a setup_frame parameter to conversation_t
2) Used the conversation_t next to maintain a list of conversations with the
same src/dest tuple but different setup_frame number.
3) Changed the signature of find_conversation() and conversation_new() to pass
in the frame number.
4) Adjusted packet-sdp to select RTP conversation if both m=audio and m=image
are present, and T.38 conversation if only m=image is present. I expect that
RTP/T.38 dissecting to be better, but I don't have a way to generate T.38

We used to reserve the protocol name NETLOGON for the old obsolete protocol

the current protocol RPC_NETLOGON instead.
that does not exactly make sense.
This renames the old obsolete protocol to SMB_NETLOGON to make way and allow

Don't check, in the dissectors for particular Gnutella packets, whether
the packet goes past the end of the tvbuff - let that throw an exception
so unreassembled packets are shown as such.
Clean up indentation.
Boost GNUTELLA_MAX_SNAP_SIZE to 4096 (one Gnutella spec suggests that
packets should be < 4K), and use it to
1) clamp the length of packets (so we don't do huge reassembly
or have problems when the total packet length, including the
header, overflows 32 bits)
and
2) check the length of packets before using tcp_dissect_pdus(),
to distinguish between packets to be reassembled and a
transfer stream.
Pass the correct value to tcp_dissect_pdus() as the header length.

Do more, and more careful, AVP length checks.
Use tvb_format_text() to display strings.
Just use "col_add_fstr()" to set the Info column - there's no need to
format into a buffer and then set the column to that buffer.
Make the L2TP dissector a "new-style" dissector and have it reject
packets with an unknown version number - the dissection effect is the
same if no other dissector claims the packet (it just gets displayed as
data), but this allows other dissectors to claim it.
Don't use the length field if the length bit isn't set.

If the information that we used to guess the payload type is part of the

layer byte in the reassembled data - including it means we have to pass
to "tvb_new_real_data()" a pointer to the *second* byte of a mallocated
chunk of data, but that would require us to have the free routine for
the new tvbuff back that pointer up before freeing it (we aren't doing
that currently, which means that "free()" either complains bitterly or,
potentially, corrupts the arena, causing crashes later).
Put in some XXX comments about some issues seen when looking at the

that doesn't mean it's padding at the end of a previous item - it might,
for example, be the *first* item in the chunk. Don't treat it as
padding.
Do, however, treat an item that begins with a zero byte as an item, but
break out of the loop processing items as soon as the item type is put
into the protocol tree, as there's no length field or data in an
RTCP_SDES_END item. Fix the comment for that loop to indicate that the
loop checks both for end-of-frame and for an RTCP_SDES_END item.

Fetch string lengths into a variable and use the variable rather than
repeatedly fetching the length from a tvbuff.
Use -1 rather than tvb_length_remaining() when putting a "to the end of

Use "proto_tree_add_item()" to put items into the tree, rather than
"proto_tree_add_xxx" calls with a "tvb_get_yyy" call as the argument.
If we've fetched a value into a variable, don't re-fetch it in

const pointer (so that we don't get complaints when we make the
tap-specific data argument to "tap_queue_packet()" a const pointer,
allowing dissectors to hand const data to a tap without a complaint), we
should make the tap per-packet function take a const pointer as an
argument as well. Do so.
In some taps, use _U_, or actually use the argument, rather than
sticking in dummy "X = X" assignments to fake use of parameters. (This
means that the tap functions in question no longer have the notion that
they act on a particular static structure wired in.)

Don't assign the const pointers passed to hash routines to non-const
