* ptvcursor_push_subtree(), ptvcursor_pop_subtree() for pushing/popping
subtrees. Multiple levels of subtrees (256 max.), allocation per 8 levels.
* Two new functions creating an item in the tree and pushing a subtree at the
same time. These two functions accept an undefined length
(SUBTREE_UNDEFINED_LENGTH). The length of the item is set at the next pop.
1) ptvcursor_add_with_subtree
2) ptvcursor_add_text_with_subtree
- get rid of potential memory leaks with g_new in ptvcursor_new().
- Documentation of the new ptvcursor functions in README.developer

by enforcing that header fields have names of length > 0. This should fix
the display of those fields and also make them filterable (which was the
subject of the bug). Abbreviations are (still) optional: if they are empty
then the field is not filterable.
Update README.developer with this information.
Add header field names in several dissectors where they were missing.
In packet-arp.c give "packet-storm-detected" a name (as above) but also set it
as _GENERATED.
Also remove trailing white space from all the files checked in.

I've had a good look at the code in packet-tcp.c, and whilst it's
somewhat impenetrable, I've come to the conclusion that it just doesn't
support multiple pdus as described.
That's not entirely unreasonable in itself; my objection is solely to
the fact that README.developer is completely misleading. In fact, even
the example dissect_cstr won't work on the tcp dissector, because if you
set desegment_len=1 the tcp dissector believes that you know what you
are doing and doesn't let you change your mind later.
Furthermore, 2.7.2 says that you can set desegment_len=-1; that doesn't
work either, because the tcp dissector expects
DESEGMENT_ONE_MORE_SEGMENT, which is 0x0fffffff, which is nowhere near -1.
In short, I think the relevant section of README.developer needs a
rewrite. I attach a patch - comments welcome.

Here is an updated patch for proto_tree_add_item and the
range_string structure. The new macro RVALS() can be used as the macro
VALS() in the declaration of your hf_register_info with another
structure (range_string). Be aware that you *have to* ORed the value of
the field display with BASE_RANGE_STRING constant and it can 'only' be
used with FT_(U)INT* types in a header_field_info.

Create two new files (ws_strsplit.[ch]) that use GTK2 code to override
the buggy g_strsplit() function when compiling for GTK1. Include this
work-around function (ws_strsplit) in libwireshark.def. Add notes on usage
to README.developer. Include epan/ws_strsplit.h in all files that use
g_strsplit().

In the Developers Guide, Section 9.3, Example 9.17. Decompressing data
packets for dissection
The code calls tvb_set_free_cb() for the newly created next_tvb. This
is unnecessary as the call to tvb_set_child_real_data() adds next_tvb to
the chained list of tvb, thus ensuring that next_tvb is correctly
deleted. In fact when I had the call in, Visual Studio kept breaking
deep down in ntdll.dll, probably because of a double free every time the
main tvb was deleted.
In README.developer, para 2..2.7 The example conversation code doesn't
assign the result of conversation_new() back into the conversation variable.

I defined a range_string struct. It's like value_string
but stores range <-> string pairs.
Moreover I wrote rval_to_str(), match_strrval_idx()
match_strrval() which are behaving exactly as
val_to_str(), match_strval_idx() and match_strval().

tcp_dissect_pdus(), pinfo->desegment_len indicates whether your
dissector needs more data from TCP or not - the return value doesn't
indicate that.
Fix typo.
It appears that the Id keyword is one of the case-insensitive ones in
the svn:keywords property, so if you set it to "ID" it still expands
"$Id$"; it also appears not to expand "$ID$". We use Revision, Date,
and Author in the document to indicate the revision, and don't expand
Id, so that references to "$Id$" get left alone.
Rewrap paragraphs.

IPv6 addresses. Use "tvb_get_ipv4()" in the WINS Replication dissector,
so that it gets the right answer on little-endian *AND* big-endian
machines.

This is very naughty and will cause problems when we have assigned a dissector to a dynamic port using conversation_set_dissector().
To make ethereal handle this case I have changed the try_conversation_dissector() to allow it to fail and return 0, meaning yes there is indeed a protocol registered for this conversation but that protocol rejected this packet.
(which only happens for "new" style dissectors, "old" style dissectors will never reject a packet that way)
When this happens the decode_udp_port() helper will still allow other dissectors to be tried, in the hope that the conversation is now used for some other protocol and thus someone else might be able to decode the packet.
Update SNMP and TFTP dissectors to check that even if there already is a conversation but that conversation does NOT have snmp/tftp registered as the dissector for it, then create a new conversation anyway and attach the proper dissector.
Since ethereal keeps track of which frame number a conversation started in, this actually works really well.
