Jörg Mayer 173fe5aef4 Replace the types from sys/types.h and netinet/in.h by their glib.h
equivalents for the toplevel directory. The removal of winsock2.h will
hopefully not cause any problems under MSVC++, as those files using
struct timeval still include wtap.h, which still includes winsock2.h.

Guy Harris ee5ca25d31 Include files from the "epan" directory and subdirectories thereof with
"epan/..." pathnames, so as to avoid collisions with header files in any
of the directories in which we look (e.g., "proto.h", as some other
package has its own "proto.h" file which it installs in the top-level
include directory).

Don't add "-I" flags to search "epan", as that's no longer necessary
(and we want includes of "epan" headers to fail if the "epan/" is left
out, so that we don't re-introduce includes lacking "epan/").

Guy Harris 92915713d3 Allow a length of -1 to be specified when adding FT_NONE and FT_PROTOCOL
items to the protocol tree; it's interpreted as "the rest of the data in
the tvbuff".  This can be used if

	1) the item covers the entire packet or the remaining payload in
	   the packet

or

	2) the item's length won't be known until it's dissected, and
	   will be then set with "proto_item_set_len()" - if an
	   exception is thrown in the dissection, it means the item ran
	   *past* the end of the tvbuff, so saying it runs to the end of
	   the tvbuff is reasonable.

Convert a number of "proto_tree_add_XXX()" calls using
"tvb_length_remaining()", values derived from the result of
"tvb_length()", or 0 (in the case of items whose length is unknown) to
use -1 instead (using 0 means that if an exception is thrown, selecting
the item highlights nothing; using -1 means it highlights all the data
for that item that's available).

In some places where "tvb_length()" or "tvb_length_remaining()" was used
to determine how large a packet is, use "tvb_reported_length()" or
"tvb_reported_length_remaining()", instead - the first two calls
indicate how much captured data was in the packet, the latter two calls
indicate how large the packet actually was (and the fact that using the
latter could cause BoundsError exceptions to be thrown is a feature - if
such an exception is thrown, the frame really *was* short, and it should
be tagged as such).

Replace some "proto_tree_add_XXX()" calls with equivalent
"proto_tree_add_item()" calls.

Fix some indentation.

Guy Harris 23319ff023 Move the pointer to the "column_info" structure in the "frame_data"
structure to the "packet_info" structure; only stuff that's permanently
stored with each frame should be in the "frame_data" structure, and the
"column_info" structure is not guaranteed to hold the column values for
that frame at all times - it was only in the "frame_data" structure so
that it could be passed to dissectors, and, as all dissectors are now
passed a pointer to a "packet_info" structure, it could just as well be
put in the "packet_info" structure.

That saves memory, by shrinking the "frame_data" structure (there's one
of those per frame), and also lets us clean up the code a bit.

Guy Harris ddfdc5bfb1 Replace the protocol-specific data in the "packet_info" structure with a
"void *" that a dissector can set to point to such a structure; that
means that the stuff in the epan directory doesn't have to know anything
about the protocol-specific private data one dissector passes to
another, and that structure doesn't have to be changed if a dissector
wants to pass some new type of data to another dissector.

Guy Harris 43ccfd8054 Add an additional "protocol index" argument to "{old_}dissector_add()",
"{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....)

Gilbert Ramirez 5b7f184296 Ensure that all value_string arrays end in {0, NULL}. Dissectors got away
with not terminating their arrays because they knew the limits of the
value used to look up strings in the value_string array, but the
dfilter_expr_dlg does not know these limits and must rely on the terminating
{0, NULL} record.

Also, in SNA fixed a bug in which a field should have been defined as FT_UINT8
but was defined as FT_BOOLEAN.

In WTP, fixed a value string which had duplicate keys.

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.

Guy Harris 252d55d80f For each column, have both a buffer into which strings for that column
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.

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 56b989e0ad Allow either old-style (pre-tvbuff) or new-style (tvbuffified)
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()".

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.

Convert proto_tree_add_*() routines to require tvbuff_t* argument.
Convert all dissectors to pass NULL argument ("NullTVB" macro == NULL) as

exception is caught.

The FDDI dissector is converted to use tvbuff's.

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

	"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
