Guy Harris 6bdba27db5 Fix a typo, discovered whilst testing the tvbuffified ISIS dissector
(the tvbuffified version is correct here; I'll check this in for
reference purposes, even though I plan to check in the tvbuffified
version later).

Guy Harris 8412393197 From Joerg Mayer: explicitly fill in all members of a
"header_field_info" structure, including the ones that are later set by
the routines to register fields.

Guy Harris 0e7c1de08a Have "proto_register_protocol()" build a list of data structures for
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.

Laurent Deniel cc36f0b931 Add the "Edit:Protocols..." feature which currently only implements
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.

Guy Harris 1cca166630 Make the "isis_hello.source_id" an FT_BYTES field rather than an
FT_ETHER field; the ISIS spec doesn't say it's necessarily a 6-byte
Ethernet address (and, if it's FT_BYTES, you can test it in a filter
much the same way you test an Ethernet address).

Make "isis_hello.lan_id" an FT_BYTES field rather than an FT_STRING
field - it's an array of bytes, not a character string.

Don't require that "system ID" fields be 6 octets; use the size value
from the ISIS PDU header.  (This means that PDUs containing "system ID"
fields can't be described as C structures; dissect them by stepping the
offset instead.)

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.

duplicate abbreviations. All mods to packet-*.c files are fixes to remove
those cases.

Guy Harris f2246ebb65 Fix a bunch of dissectors to use "pi.captured_len" rather than
"fd->cap_len" for the frame length - or to use macros such as
"BYTES_ARE_IN_FRAME()", "IS_DATA_IN_FRAME()", and "END_OF_FRAME", which
use "pi.captured_len" - so that they correctly handle frames where the
actual data length of the packet is less than the size of the raw frame,
e.g. with encapsulations such as ISL.

Gilbert Ramirez 339d67b043 Merge in the final code to make Ethereal run on Win32, compiled
with MSVC 6.0 and 'nmake', the make tool that comes with MSVC.

It compiles, links, and runs. It doesn't run correctly. There's a problem
when reading files. I'm getting short reads.  I'm not linking in zlib or
libsnmp because it first needs to be debugged.

I changed the plugin code to use gmodule instead of libltdl, but the
Unix build still links ethereal against libltdl. I'll fix that tonight; sorry
about leaving it in such a sad state, but I wanted to check in this code
before I left work on a Friday night. Ethereal still works, but the
building is less than optimal.
