have two independent "value_string" tables mapping RFC 1700 address
family numbers to names, nor is there any need to have the BGP dissector
and the PIM dissector have two independent sets of #defines for RFC 1700
address family numbers; put a single "value_string" table in "afn.c" and
put a declaration of it, and #defines for the address family numbers,
into "afn.h", and have the dissectors use that.
Move the #define for PGM into "ipproto.h", and add an entry for it in
the "value_string" table in "ipproto.c".
Have the PGM dissector use the standard Ethereal mechanisms for
resolving addresses, and have it use "value_string" tables for mapping
option types, the OPX bits, and packet types to strings. Use
"bytes_to_str()" to turn byte arrays into strings of hex digits. Pass
the packet type string to "dissect_pgmopts()" as an argument, rather
than making it a global. Don't use "proto_tree_add_XXX_format" routines
if you can possibly just use "proto_tree_add_XXX"; give various fields
the correct radix and type, and VALS() strings if necessary, to make
that happen (and to make filtering on them more pleasant). Put the
type, length, and total length of the options into the protocol tree as
separate fields. Don't have separate type, length, and OPX fields for
every type of option; one field will suffice. Don't format a string
with "sprintf()" and then pass that string to "col_add_fstr()" with a
format of "%s" and the string as an argument - "col_add_fstr()" can
format strings itself (that's what the "f" stands for). Don't byte-swap
and then un-byte-swap IPv4 address fields in the header, just leave them
network byte order to start with. Use the correct fields for
"proto_tree_add_XXX", rather than using the same field multiple times.
Quit early if an address family identifier isn't AFNUM_INET, as that
means the structure we use to dissect the header doesn't match the
actual header.

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.
"Tvbuffify" the Mobile IP dissector (it took old-style arguments, and
then converted them into tvbuff arguments, so there wasn't much to do,
other than to fix references to "fd" to refer to "pinfo->fd").
In the SCTP dissector, refer to the port type and source and destination
ports through "pinfo" rather than through the global "pi", as it's a
tvbuffified dissector.
In the SMTP and Time Protocol dissectors, use "pinfo->match_port" rather
than "TCP_PORT_SMTP" when checking whether the packet is a request or
reply, just in case somebody makes a non-standard port be dissected as
SMTP or Time. (Also, remove a bogus comment from the Time dissector; it
was probably cut-and-pasted from the TFTP dissector.)

"{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....)

"prefs_register_module()" except that it takes a protocol index as
returned by "proto_register_protocol()" as its first argument, rather
than taking two character strings as arguments as its first two
arguments, and uses the protocol's abbreviation as the name to use for
preferences in the preferences file and the "-o" flag and uses the
protocol's short name as the name to use in the tabs in the
"Edit->Preferences" window.

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

Still more work to do though, as I want to dissect the various message
types correctly, and to dissect TLVs much more as well.
The dissector currently handles multiple messages in a PDU, as the trace
file I have has some of those.
I think that the equipment that generated the LDP trace I have has a bug.
It seems to think that TLVs must be alligned on 4-byte boundaries, while the
spec (draft) says that there are no alignment requirements :-)
Don't know what generated the trace :-)

It registers the same dissector for the LDP port for both TCP and UDP.
Still a lot of work to do, but we can see the header now.
