"pinfo->srcport", and "pinfo->destport" appropriately in the IPX
dissector. Add support for PT_IPX port types in display columns.
Have an "spx.socket" dissector table, similar to the "ipx.socket"
dissector table, and have the SPX dissector use that, with the IPX
socket numbers from "pinfo->srcport" and "pinfo->destport", so that
dissectors for protocols that run atop SPX can register with particular
socket numbers. (Think of it as similar to what would have been the
case had the IP header had 16-bit source and destination port numbers,
and had TCP and UDP used those port numbers rather than having port
numbers in their headers.) Also, have the SPX dissector dissect
subprotocols regardless of whether we're building a protocol tree or not.
Use the dissector handle for the IPX message dissector for both IPX
socket numbers; there's no need to create separate handles for both
registrations.
Have NDPS register as a subdissector of the SPX dissector, using
"spx.socket", and get rid of the duplicate SPX dissection in the NDPS
dissector.
Make the NDPS dissector set the columns regardless of whether a protocol
tree is being built, and clean up the dissector (fixing some bugs).
Get rid of unneeded includes in "packet-ndps.c".

"broadcast message waiting" indications.
When handing off dissection from the IPX dissector:
Check the socket numbers before we check the packet type;
we've seen IPX message packets with a type of NCP and a
destination socket of IPX_SOCKET_IPX_MESSAGE, and SAP
packets with a type of NCP and a destination socket of
IPX_SOCKET_SAP.
Assume the lower-numbered socket number is more likely
to be the right one, along the lines of what we do for
TCP and UDP. We've seen NCP packets with a type of NCP,
a source socket of IPX_SOCKET_NCP, and a destination
socket of IPX_SOCKET_IPX_MESSAGE, and we've seen NCP
packets with a type of NCP, a source socket of
IPX_SOCKET_IPX_MESSAGE, and a destination socket of
IPX_SOCKET_NCP.

Replace some calls to "tvb_length()" or "tvb_length_remaining()" with
calls to "tvb_reported_length()" and "tvb_reported_length_remaining()",

"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.

Make the source and destination socket fields enumerated types, so we
don't have to use "proto_tree_add_uint_format()" on them, and so that

"pinfo->{len,captured_len}"-adjusting currently done by the IP
dissector, make the IP dissector call that rather than doing the work
itself, make the IPv6 dissector call that rather than just adjusting the
tvbuff length itself, and make the IPX dissector call that rather than
just adjusting "pi.{len,captured_len}" itself.
This cleans things up a bit, and causes trailers to be properly reported
in IPX-over-Ethernet frames.

Make a separate dissector for Cisco HDLC, and add a dissector for Cisco
SLARP. Have the PPP dissector call the Cisco HDLC dissector if the
address field is the Cisco HDLC unicast or multicast address. Use the
Cisco HDLC dissector for the Cisco HDLC Wiretap encapsulation type.
Add a new dissector table "chdlctype", for Cisco HDLC packet types
(they're *almost* the same as Ethernet types, but 0x8035 is SLARP, not
Reverse ARP, and 0x2000 is the Cisco Discovery protocol, for example),
replacing "fr.chdlc".
Have a "chdlctype()" routine, similar to "ethertype()", used both by the
Cisco HDLC and Frame Relay dissectors. Have a "chdlc_vals[]"
"value_string" table for Cisco HDLC types and protocol names. Split the
packet type field in the Frame Relay dissector into separate SNAP and
Cisco HDLC fields, and give them the Ethernet type and Cisco HDLC type
"value_string" tables, respectively.

"{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....)

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.
