people don't blindly insert the old address into new dissectors, which
is probably how it got into the dissectors being fixed here.

statements.
Move the setting of the Protocol column in various dissectors before
anything is fetched from the packet, and also clear the Info column at
that point in those and some other dissectors, so that if an exception
is thrown, the columns don't reflect the previous protocol.
"Tvbuffify" the Mobile IP dissector (it took old-style arguments, and
then converted them into tvbuff arguments, so there wasn't much to do,
other than to fix references to "fd" to refer to "pinfo->fd").
In the SCTP dissector, refer to the port type and source and destination
ports through "pinfo" rather than through the global "pi", as it's a
tvbuffified dissector.
In the SMTP and Time Protocol dissectors, use "pinfo->match_port" rather
than "TCP_PORT_SMTP" when checking whether the packet is a request or
reply, just in case somebody makes a non-standard port be dissected as
SMTP or Time. (Also, remove a bogus comment from the Time dissector; it
was probably cut-and-pasted from the TFTP dissector.)

"{old_}heur_dissector_add()", "{old_}conv_dissector_add()", and
"register_dissector()", so that an entry in those tables has associated
with it the protocol index of the protocol the dissector handles (or -1,
if there is no protocol index for it).
This is for future use in a number of places.
(Arguably, "proto_register_protocol()" should take a dissector pointer
as an argument, but
1) it'd have to handle both regular and heuristic dissectors;
2) making it take either a "dissector_t" or a union of that and
a "heur_dissector_t" introduces some painful header-file
interdependencies
so I'm punting on that for now. As with other Ethereal internal APIs,
these APIs are subject to change in the future, at least until Ethereal
1.0 comes out....)

protocols, in addition to adding structures to the list of filterable
fields. Give it an extra argument that specifies a "short name" for the
protocol, for use in such places as
pinfo->current_proto;
the dialog box for constructing filters;
the preferences tab for the protocol;
and so on (although we're not yet using it in all those places).
Make the preference name that appears in the preferences file and the
command line for the DIAMETER protocol "diameter", not "Diameter"; the
convention is that the name in question be all-lower-case.
Make some routines and variables that aren't exported static.
Update a comment in the ICP dissector to make it clear that the
dissector won't see fragments other than the first fragment of a
fragmented datagram.

can be put, and a pointer to the string for the column, which might or
might not point to that buffer.
Add a routine "col_set_str()", which sets the string for the column to
the string passed to it as an argument; it should only be handed a
static string (a string constant would be ideal). It doesn't do any
copying, so it's faster than "col_add_str()".
Make the routines that append to columns check whether the pointer to
the string for the column points to the buffer for the column and, if
not, copy the string for the column to the buffer for the column so that
you can append to it (so you can use "col_set_str()" and then use
"col_append_str()" or "col_append_fstr()").
Convert a bunch of "col_add_str()" calls that take a string constant as
an argument to "col_set_str()" calls.
Convert some "col_add_fstr()" calls that take a string constant as the
only argument - i.e., the format string doesn't have any "%" slots into
which to put strings for subsequent arguments to "col_set_str()" calls
(those calls are just like "col_add_str()" calls).
Replace an END_OF_FRAME reference in a tvbuffified dissector with a
"tvb_length(tvb)" call.

protocols running atop SCTP can register themselves with a particular
SCTP port number.
Also, clean up the credits for him - there were two entries, one for
some initial SCTP support in "ipprotostr()" and in the capture dialog,
and one for the SCTP dissector itself - the latter subsumes the former,
so just keep the latter.

the following:
It is now possible to enable/disable a particular protocol decoding
(i.e. the protocol dissector is void or not). When a protocol
is disabled, it is displayed as Data and of course, all linked
sub-protocols are disabled as well.
Disabling a protocol could be interesting:
- in case of buggy dissectors
- in case of wrong heuristics
- for performance reasons
- to decode the data as another protocol (TODO)
Currently (if I am not wrong), all dissectors but NFS can be disabled
(and dissectors that do not register protocols :-)
I do not like the way the RPC sub-dissectors are disabled (in the
sub-dissectors) since this could be done in the RPC dissector itself,
knowing the sub-protocol hfinfo entry (this is why, I've not modified
the NFS one yet).
Two functions are added in proto.c :
gboolean proto_is_protocol_enabled(int n);
void proto_set_decoding(int n, gboolean enabled);
and two MACROs which can be used in dissectors:
OLD_CHECK_DISPLAY_AS_DATA(index, pd, offset, fd, tree)
CHECK_DISPLAY_AS_DATA(index, tvb, pinfo, tree)
See also the XXX in proto_dlg.c and proto.c around the new functions.

- add <stdarg.h> or <varargs.h> in snprintf.h
and remove those inclusions in the other #ifdef NEED_SNPRINTF_H codes
- remove the check of multiple inclusions in source (.c) code
(there is a bit loss of _cpp_ performance, but I prefer the gain of
code reading and maintenance; and nowadays, disk caches and VM are
correctly optimized ;-).
- protect all (well almost) header files against multiple inclusions
- add header (i.e. GPL license) in some include files
- reorganize a bit the way header files are included:
First:
#include <system_include_files>
#include <external_package_include_files (e.g. gtk, glib etc.)>
Then
#include "ethereal_include_files"
with the correct HAVE_XXX or NEED_XXX protections.
- add some HAVE_XXX checks before including some system header files
- add the same HAVE_XXX in wiretap as in ethereal
Please forgive me, if I break something (I've only compiled and regression
tested on Linux).

dissectors to be registered as dissectors for particular ports,
registered as heuristic dissectors, and registered as dissectors for
conversations, and have routines to be used both by old-style and
new-style dissectors to call registered dissectors.
Have the code that calls those dissectors translate the arguments as
necessary. (For conversation dissectors, replace
"find_conversation_dissector()", which just returns a pointer to the
dissector, with "old_try_conversation_dissector()" and
"try_conversation_dissector()", which actually call the dissector, so
that there's a single place at which we can do that translation. Also
make "dissector_lookup()" static and, instead of calling it and, if it
returns a non-null pointer, calling that dissector, just use
"old_dissector_try_port()" or "dissector_try_port()", for the same
reason.)
This allows some dissectors that took old-style arguments and
immediately translated them to new-style arguments to just take
new-style arguments; make them do so. It also allows some new-style
dissectors not to have to translate arguments before calling routines to
look up and call dissectors; make them not do so.
Get rid of checks for too-short frames in new-style dissectors - the
tvbuff code does those checks for you.
Give the routines to register old-style dissectors, and to call
dissectors from old-style dissectors, names beginning with "old_", with
the routines for new-style dissectors not having the "old_". Update the
dissectors that use those routines appropriately.
Rename "dissect_data()" to "old_dissect_data()", and
"dissect_data_tvb()" to "dissect_data()".

causes a system <packet.h> header to be includes, which causes the
