Gilbert Ramirez eb633dffce For packets with GIOP versions that are not supported by the dissector,
identify the packet as GIOP, but let the user know that the version is
not supported.

Guy Harris 283ce59938 Add routines for adding items to a protocol tree that take arguments of
a particular type, rather than taking a varargs list, along the lines of
the "proto_tree_add_XXX_format()" routines.

Replace most calls to "proto_tree_add_item()" and
"proto_tree_add_item_hidden()" with calls to those routines.

Rename "proto_tree_add_item()" and "proto_tree_add_item_hidden()" to
"proto_tree_add_item_old()" and "proto_tree_add_item_hidden_old()", and
add new "proto_tree_add_item()" and "proto_tree_add_item_hidden()"
routines that don't take the item to be added as an argument - instead,
they fetch the argument from the packet whose tvbuff was handed to them,
from the offset handed to them.

Gilbert Ramirez 292e38e2c6 Add tvbuff class.
Add exceptions routines.
Convert proto_tree_add_*() routines to require tvbuff_t* argument.
Convert all dissectors to pass NULL argument ("NullTVB" macro == NULL) as
the tvbuff_t* argument to proto_tree_add_*() routines.

dissect_packet() creates a tvbuff_t, wraps the next dissect call in
a TRY block, will print "Short Frame" on the proto_tree if a BoundsError
exception is caught.

The FDDI dissector is converted to use tvbuff's.

Guy Harris 6bbfd97bde Add routines to:
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).

Gilbert Ramirez f6e92a9e93 Break proto_tree_add_item_format() into multiple functions:
proto_tree_add_protocol_format()
	proto_tree_add_uint_format()
	proto_tree_add_ipxnet_format()
	proto_tree_add_ipv4_format()
	proto_tree_add_ipv6_format()
	proto_tree_add_bytes_format()
	proto_tree_add_string_format()
	proto_tree_add_ether_format()
	proto_tree_add_time_format()
	proto_tree_add_double_format()
	proto_tree_add_boolean_format()
If using GCC 2.x, we can check the print-format against the variable args
passed in. Regardless of compiler, we can now check at run-time that the
field type passed into the function corresponds to what that function
expects (FT_UINT, FT_BOOLEAN, etc.)

Note that proto_tree_add_protocol_format() does not require a value field,
since the value of a protocol is always NULL. It's more intuitive w/o the
vestigial argument.

Fixed a proto_tree_add_item_format-related bug in packet-isis-hello.c
Fixed a variable usage bug in packet-v120.c. (ett_* was used instead of hf_*)

Checked in Guy's fix for the function declearation for proto_tree_add_text()
and proto_tree_add_notext().

Guy Harris a7aba0a288 Replace the ETT_ "enum" members, declared in "packet.h", with
dynamically-assigned "ett_" integer values, assigned by
"proto_register_subtree_array()"; this:

	obviates the need to update "packet.h" whenever you add a new
	subtree type - you only have to add a call to
	"proto_register_subtree_array()" to a "register" routine and an
	array of pointers to "ett_", if they're not already there, and
	add a pointer to the new "ett_" variable to the array, if they
	are there;

	would allow run-time-loaded dissectors to allocate subtree types
	when they're loaded.

Gilbert Ramirez bacb9d5bae New proto_tree header_field_info stuff. Header_field_infos now contain
the base for numbers to be displayed in, bitmasks for bitfields, and blurbs
(which are one or two sentences describing the field).

proto_tree_add*() routines now automatically handle bitfields. You tell
it which header field you are adding, and just pass it the value of the
entire field, and the proto_tree routines will do the masking and shifting
for you.

This means that bitfields are more naturally filtered via dfilter now.

Added Phil Techau's support for signed integers in dfilters/proto_tree.

Added the beginning of the SNA dissector. It's not complete, but I'm
committing it now because it has example after example of how to use
bitfields with the new header_field_info struct and proto_tree routines.
It was the impetus to change how header_field_info works.

Guy Harris 96e79ab6f8 Add a "BYTES_ARE_IN_FRAME()" macro, to test whether there are a
specified number of bytes of captured data in the frame at the specified
offset, and a "IS_DATA_IN_FRAME()" macro, to test whether there are any
bytes of captured data in the frame at the specified offset, and convert
some bounds checks to use them.

Add a dissector for the Internet Printing Protocol.

Guy Harris f93c76fd10 Convert a bunch of uses of "fd->cap_len" to use "pi.captured_len" (or to
use END_OF_FRAME), so that they don't look at stuff in an IP datagram
past the end of the IP datagram (i.e., frame padding).

Gilbert Ramirez 7bd6c15378 Made the protocol (but not the fields) use the new proto_tree routine,
allowing users to filter on the existence of these protocols. I also
added packet-clip.c to the Nmake makefile.

Gilbert Ramirez 07f42b5b31 Created a new protocol tree implementation and a new display filter
mechanism that is built into ethereal. Wiretap is now used to read all
file formats. Libpcap is used only for capturing.

Gilbert Ramirez ef3dfe2077 Removed all references to gtk objects from packet*.[ch] files. They now
reference the protocol tree with struct proto_tree and struct proto_item
objects. That way, the packet decoding source code file can be used with
non-gtk packet decoders, like a curses-based ethereal, e.g. I also re-arranged
some of the information in packet.h to more appropriate places (like other
packet-*.[ch] files).
