take a dissector handle as an argument, rather than a pointer to a
dissector function and a protocol ID. Associate dissector handles with
dissector table entries.

former depends on having "guint64" and the latter depends on
"%ll[douxX]" being what's used to print 64-bit integers, and there are
platforms on which Etheeal runs that don't have "guint64" or that don't
use "%ll[douxX]" to print 64-bit integers.
Get rid of the routines to extract 64-bit integers into "gint64"s and
"guint64"s, as per Ronnie Sahlberg's suggestion, to discourage people
from writing code that won't work on all platforms; they should be using
FT_UINT64, or the routines in "int-64bit.c", instead.

"proto_item_set_text()" except that it appends the result of the
formatting to the item's current text, rather than replacing the item's
current text. Use it in the DNS dissector.
svn path=/trunk/; revision=3880
but, before you set the text, you throw an exception while putting stuff
under the subtree, you end up with an absolutely blank protocol tree
item, which is really gross. Instead of calling
"proto_tree_add_notext()", call "proto_tree_add_text()" with at least a
minimal label - yes, it does mean you do some work that will probably be
unnecessary, but, absent a scheme to arrange to do that work if it *is*
necessary (e.g., catching exceptions), the alternative is an ugly
protocol tree display.

be loaded and their initialization routines called in right after we
call the initialization routines for built-in dissectors, but don't call
their handoff registration routines yet, and then call the handoff
registration routines right after calling the handoff registration
routines for built-in dissectors.
Do all that in "proto_init()", rather than "epan_init()".
That way, we call all dissector registration routines together, and then
call all dissector handoff registration routines together; all the
registration routines are called before any handoff registration
routines, as is required, and, as "proto_init()" is called by
"epan_init()" before "dfilter_init()" is called, all filterable fields
have been registered before "dfilter_init()" is called, and no plugins
have to call "dfilter_init()" themselves to get their fields registered.
Remove pointers to "dfilter_init()" and "dfilter_cleanup()" from the
plugin address table, as plugins shouldn't be calling them any more, and
remove calls to them from plugins.

returned by "proto_register_protocol()" as its first argument, rather
than taking two character strings as arguments as its first two

preferences in the preferences file and the "-o" flag and uses the
protocol's short name as the name to use in the tabs in the
"Edit->Preferences" window.

dissector can get a "handle" for that dissector by name and then call
that dissector through the handle.
This allows dissectors that can't be called through a port table or a
heuristic table to be called from other dissectors without directly
referring to the dissector function - dynamically-loaded modules, under
Windows, cannot directly call functions in the main program, and
non-plugin dissectors are in the main program and thus cannot be called
from plugin dissectors unless either
1) a pointer to the dissector is put in the Big Transfer Vector
or
2) some other mechanism for getting a pointer to the dissector
is provided.
This mechanism could also support registering old-style dissectors and
calling them from new-style dissectors without the new-style dissector
having to do the argument translation itself (I didn't add support for
registering old-style dissectors because I'd prefer to have people
tvbuffify their code if they have to register a dissector...).
It could also, in the future, perhaps support
disabling of protocols;
setting "pinfo->current_proto";
inside "call_dissector()" - and inside "{old_}dissector_try_port()" and
"{old_"dissector_try_heuristic()" - allowing a pile of stuff that
currently has to be done in every dissector be done by common code.
(I have some ideas about how to do this, by
having "proto_register_protocol()" take an abbreviation - of the
sort that would be put in, for example, "pinfo->current_proto" -
as an argument;
having the calls to register dissectors take an index returned
by "proto_register_protocol()" as an argument.
The abbreviation could be used elsewhere as well, e.g. in the "Decoding"
tab of the "Edit->Protocols" dialog box, and in a GUI for constructing
protocol filters. Watch this space.)
Make "dissect_sdp()" the first client of this mechanism; it's now static
to "packet-sdp.c", and all dissectors that call it - including the MGCP
plugin - now call it through a dissector handle fetched by
"find_dissector()". (Next step - see if Ethereal can now compile on
Windows as a result of this.)

Fix plugin-table lines for "dissector_delete()", "dissect_data()",

The MGCP dissector uses routines from GLib, so when building it as a DLL

"plugins/Makefile.nmake" to build that plugin.
Add to the table of routines callable from plugins
"old_dissector_add()", "old_dissect_data()", and
"proto_is_protocol_enabled()", so that the Gryphon dissector can build
on Windows.
Move the includes of "plugins/plugin_api.h" and "moduleinfo.h" before
all the other includes, except for "config.h", in "plugin-mgcp.c", to
match what the Gryphon dissector does; "plugins_api.h" must be included
before any of the routines whose names it #defines in order for the
plugin to build on Windows. (It still doesn't build on Windows, as
still more routines need to be added to the table of routines callable
from plugins, but tomorrow is another day. Making libethereal a DLL may
obviate the need for that table, *if* all the routines called from a
plugin are in libethereal, as I think routines in a DLL, even a
run-time-loaded DLL, can call routines from another DLL as long as those
routines are exported from the other DLL.)

- 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).

register lists of "heuristic" dissectors, which are handed a
frame that may or may contain a payload for the protocol they
dissect, and that return FALSE if it's not or dissect the packet
and return TRUE if it is;
add a dissector to such a list;
go through such a list, calling each dissector until either a
dissector returns TRUE, in which case the routine returns TRUE,
or it runs out of entries in the list, in which case the routine
returns FALSE.
Have lists of heuristic dissectors for TCP and for COTP when used with
the Inactive Subset of CLNP, and add the GIOP and Yahoo Messenger
dissectors to the first list and the Sinec H1 dissector to the second
list.
Make the dissector name argument to "dissector_add()" and
"dissector_delete()" a "const char *" rarther than just a "char *".
Add "heur_dissector_add()", the routine to add a heuristic dissector to
a list of heuristic dissectors, to the set of routines we can export to
plugins through a table on platforms where dynamically-loaded code can't
call stuff in the main program, and initialize the element in the table
in question for "dissector_add()" (which we'd forgotten to do).
