suffices; have the heuristic dissector call the message dissector and
return FALSE if the message dissector returns 0 (meaning it's not a
STUN2 packet) and TRUE otherwise.
New-style dissectors don't return a Boolean, they return 0 if the packet
isn't a packet for that protocol and the number of bytes dissected
otherwise. (Yes, that's a problem if the length of the tvbuff handed to
the dissector is 0; that's why new-style dissectors aren't yet the
default.)

epan/dissectors/packet-ncp2222.inc is a bit hard to fix, so we're not
ready to enable that warning by default yet.
Throw in some casts to handle GLib routines that take arbitrary
non-const pointers (they can later return the pointers, and some
callers might want to modify or free up those pointers in cases where
they're known to be writable or allocated).
Use ep_tvb_memdup() rather than a combination of ep_alloc() and
tvb_memcpy().
Clean up some indentation.

this is an update to the STUN2 dissector using the last draft,
draft-ietf-behave-rfc3489bis-15
- add TURN extension support (probably incomplete) from
draft-ietf-behave-turn-07
- add some descriptive text for attributes upper in tree (it avoids developing
the tree completely to see essential attributes values)
svn path=/trunk/; revision=25138
When offset parameter is 0 replace tvb_bytes_exist() with the faster tvb_length().
On the other hand
if (tvb_bytes_exist(tvb, 0, 20)
is more readable than
if (tvb_length(tvb) >= 20
so only do it in heuristic function

last draft, draft-ietf-behave-rfc3489bis-07. Changelog:
* My employer is now sponsoring this work, so added a copyright line.
* Added a comment for each method/attribute with the RFC/I-D where is
it defined, so it will be easier to add new STUN usages.
* Removed the SHARED-SECRET method.
* Removed the PASSWORD and REFRESH-INTERVAL attributes.
* Changed "Response" to "Success Response".
* Changed "Error Reason Phase" to "Error Reason Phrase".
* Added reassembly for TCP segments on STUN2.
* Updated STUN acronym expansion.
* Renamed STUN2_ERROR to ERROR_RESPONSE.
* Changed the value of attribute FINGERPRINT from 0x8025 to 0x8028.
* Display if an unknown attribute is comprehension-optional or
comprehension-required.
* Reorganized order of attributes in the dissector code.
* The message length is now displayed in decimal.

This is a new dissector for STUN v2, that is currently in WGLC at the IETF.
- Keep packet-stun.c for the RFC 3498 protocol, plus the STUN and TURN
drafts up to draft-ietf-behave-rfc3489bis-02 and
draft-rosenberg-midcom-turn-08, as there is some huge deployments using
this. There will be no modification to this dissectors in the future,
excepted perhaps to add support for retransmission or things like this.
- Add a new dissector packet-stun2.c for the new STUN (currently in
WGLC), the STUN relay-usage (formerly known as TURN) and the other
usages that will be added in the future (IPv6, NAT Behavior, etc...).
