they have LF at the end of the line on UN*X and CR/LF on Windows;
hopefully this means that if a CR/LF version is checked in on Windows,
the CRs will be stripped so that they show up only when checked out on
Windows, not on UN*X.

"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/").

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.

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.
Don't use
col_add_fstr(..., "%s", string);
Use
col_add_str(..., string);
as it does the same thing, but doesn't drag all the heavy *printf
machinery in.
Fix the DDTP dissector to set the Info column regardless of whether
we're building a protocol tree or not, and to set it to "Encrypted
payload" if the payload is encrypted. Also fix a typo in a field name.
Register the FTP data dissector as being associated with the FTP data
protocol, not the FTP protocol (the removed "CHECK_DISPLAY_AS_DATA()"
call checked "proto_ftp_data", and the removed "pinfo->current_proto ="
line set it to "FTP-DATA", so it should be associated with
"proto_ftp_data").
Make the H1 dissector check whether the frame has at least 2 bytes in it
before checking the first two bytes; heuristic dissectors must not throw
exceptions until they've accepted the packet as one of theirs.
Use "tvb_format_text()" rather than "tvb_get_ptr()" and "format_text()"
in some dissectors where the result of "tvb_get_ptr()" is used only in
the "format_text()" call.
In the Quake dissector, don't check whether there are at least 4 bytes
in the packet - if we return, the packet won't be dissected at all (it's
not as if some other dissector will get to handle it), and, if we don't
return, we'll throw an exception if there aren't at least 4 bytes in the
packet, so the packet will be marked as short or malformed, as
appropriate.
In the RIPng dissector, associate the table of strings for the command
field with the command field, so that the dissector doesn't have to
format the string for the protocol tree entry itself, and so that the
filter construction dialog box can let you select "Request" or
"Response" from a list rather than requiring you to know the values for
"Request" and "Response".
Make "dissect_rpc()" static, as it's called only through a heuristic
dissector list.
Use "col_set_str()" to set the COL_PROTOCOL column for RPC protocols;
the string used is from a table provided by the dissector, and is a
string constant.
Don't format the Info column for WSP into a buffer and then format that
buffer into the column with "%s" - "col_add_fstr()" can do the
formatting for you, without having to allocate your own buffer (or run
through the *printf machinery twice).
Don't fetch fields from the WTP packet until you're ready to use them,
so that you don't throw an exception before you even set the Protocol
column or clear the Info column.
Use "pinfo->destport", not "pi.destport", in the Zebra dissector when
checking whether the packet is a request or reply, and do the check by
comparing with "pinfo->match_port" rather than TCP_PORT_ZEBRA (so that
if the dissector is ever registered on another port, it still correctly
determines whether the packet is a request or reply - the Network
Monitor HTTP dissector has port 80 wired into its brain, which is a bit
irritating if you're trying to get it to dissect HTTP proxy traffic on
port 3128 or proxy administration UI traffic on port 3132).

"{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.

dissector call it through a handle, and make it static.
Give "dissect_data()" an "offset" argument, so dissectors can use it to
dissect part of the packet without having to cook up a new tvbuff.
Go back to using "dissect_data()" to dissect the data in an IPP request.

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.

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()".

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.

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.

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).

1) fix some problems with the SINEC H1 dissector;
2) make it easier to plug in other dissectors atop OSI transport
protocols (by making the H1 dissector return an indication of
whether it recognizes the packet as an H1 packet or not, so
that, if it doesn't, additional dissectors can be tried).
