hopefully not cause any problems under MSVC++, as those files using
struct timeval still include wtap.h, which still includes winsock2.h.

1. Add some VSAs.
2. Modify the routines match_numval() and
rd_match_strval_attrib() to use a null string pointer, rather
than a 0 value, to signify the end of the attribute table,
because some vendors are using an attribute with a value of 0.
3. Bug fix.

and other changes to RADIUS.
Export the Q.931 cause location and code values, and use them in the
RADIUS dissector for ACC cause codes and values.
Make "CHAP" all caps, as it should be, and use InterCaps in AppleTalk
(Apple does).
The CHAP Challenge is an octet string, not a text string - the
FreeRadius dictionary has an error there.
In "rdconvertinttostr()", if there's no value_string table, just print
the value numerically, don't call "rd_match_strval()".
Don't pass a null value_string pointer to "rd_match_strval_attrib()" -
just report the value, without attempting to find a string for it.

When displaying text strings, show escapes in octal (as is done C)

Display RADIUS_BINSTRING values as strings of hex digits rather than as

The return value of "rdconvertbufftostr()" is never used; get rid of it.

of the LEAP negotiation, so we can properly dissect the LEAP message
after the first pass through the packets.
For that to be computed correctly, EAP frames have to be dissected on
the first pass through the capture file, even if the protocol tree isn't
being generated; that means that RADIUS AVPs need to be dissected even
if the protocol tree isn't being generated.

dissectors. "Old-style" dissectors return nothing. "New-style"
dissectors return one of:
a positive integer, giving the number of bytes worth of data in
the tvbuff that it considered to be part of the PDU in the
tvbuff;
zero, if it didn't consider the data in the tvbuff to be a PDU
for its protocol;
a negative integer, giving the number of additional bytes worth
of data in needs to get the complete PDU (for use with
fragmentation/segmentation when the length of the PDU isn't
known to the protocol atop the one the dissector is dissecting).
Have "call_dissector()" return the return value of new-style dissectors,
and the length of the tvbuff handed to it for old-style dissectors.
Have "dissector_try_port()" return FALSE if the subdissector is a
new-style dissector and returned 0.
Make the EAP dissector a new-style dissector, and have a "EAP fragment"
dissector that is also a new-style dissector and handles fragmentation
of EAP messages (as happens above, for example, RADIUS). Also, clean up
some signed vs. unsigned comparison problems.
Reassemble EAP-Message AVPs in RADIUS.

"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.

"{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.

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.

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.
