RTP analysis' jitter values are thrown off by RTP events
http://bugs.wireshark.org/bugzilla/show_bug.cgi?id=1076
a) Ephemeral string (packet duration) was inserted into long-term hash of
dynamic payloads
b) There was no clock_rate mapping for MIME type "telephone-event".

- s/ntohl/g_ntohl
- s/free/g_free
- Change some tvb_get_string()+g_free()'s into tvb_get_ephemeral_string()
- Change some tvb_fake_unicode()+g_free()'s into tvb_get_ephemeral_faked_unicode()
- Change some tvb_get_string() calls that were clearly memory leaks (like
atoi(tvb_get_string(...))) into tvb_get_ephemeral_string()

This patch adds support for key-mgmt session attributes in SDP (defined in RFC 4567). The patch also contains a Multimedia Internet KEYing (MIKEY is defined in RFC 3830) dissector plugin for "mikey" key-mgmt data.
svn path=/trunk/; revision=20977
- allow SDP to parse the IP address + port for the MSRP session from the
path attribute
- setup an MSRP conversation using this address, whose data points back
to the SDP frame
- link to the SDP setup frame while dissecting MSRP (can be switched off
by a preference)
- I also changed sdp.media.port to be a numeric field
svn path=/trunk/; revision=18806
- while parsing fmtp lines, the dissector looks for the MPEG4 'profile-level-id' parameter. If there is no '=' present, it was throwing an exception and the frame marked as malformed (see e.g. the attached
capture)
- I've added a few comments where the code wasn't obvious to me...

I attached patch to add preferences in SDP for RTP stream detection. By default SDP decodes RTP stream but now I can disable it.

Save the media encoding name in the transport_info_t structure rather
than in a global variable. Allocate it with tvb_get_ephemeral_string()
so it's released after the packet is completely processed. Do *NOT*
assume it's necessarily non-null in decode_sdp_fmtp(), as the code flow
doesn't guarantee that to be true.
proto_tree_add_string() now suffices for adding a particular SDP item -
strings are now displayed "safely", with escaping of non-printable
characters done.
Update a comment (we no longer have the Big Transfer Vector to allow
plugins to call dissector functions in Windows, we have those functions
in a DLL).

This fixes bug 523, but exposes more of bug 658.
The TACACS and SDP dissectors don't call inet_aton(), so don't include it.

Find attached a couple of changes for t38:
- Use the dissector to reassemble t30 frames
- Dissect t30 protocol
- Move the "Fax t38 analysis" to the "VoIP Calls". Now when selecting
"Statistics"->"Fax t38 analysis" option, there is a message that
redirect the user to use the "Voip calls" instead. We may keep this
option for one release, and then remove it ?
- Added in the "Voip calls" the ability to detect a t38 call if there
are not signaling associated with it. For example, when using "Decode
as.." to dissect t38 packets, it is possible to use the "Voip calls" to analyze that call.
- Display "SDP (t38)" in the "Voip calls graph" for SDP t38 sessions.

directory to the epan directory. Some of them should perhaps ultimately
be moved to epan/dissectors, if they pertain only to stuff exported by a
particular dissector.
Fix Gerald's e-mail address in files we're moving.

improve dissection of Dynamic payload
types used in conversations and the
codec list summary in the "Voip Calls Graph".
svn path=/trunk/; revision=14180
- bump up SDP_MAX_PAYLOAD_TYPES to 20 (I have an mgcp capture where a media
gateway responded with 12 media types, resulting in a crash). Probably more
care needs to be taken while parsing the list of media types though...

From Alejandro Vaquero :
Find attached a patch for SDP sessions to:
- Dissect Dynamic payload types in RTP packets
- Add the dynamic payload type description in RTP packets
- Add RTP dynamic payload types description in the Voip Calls Graph, in the RTP and SDP.
svn path=/trunk/; revision=13940
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
packets.

h323 taps support up to 5 messages per packet now.
VoIP call analysis:
- Collect ISUP, SIP and H323 calls from a capture and show them in window with the following info:
- Start and Stop time of the call
- Init
svn path=/trunk/; revision=13225
Also move ncp222.py, x11-fields, process-x11-fields.pl,
make-reg-dotc, and make-reg-dotc.py.
Adjust #include lines in files that include packet-*.h
files.
