Guy Harris ac4f87218d Declare the "packet_info" structure "pi" in "packet.h", rather than in a
bunch of source files.

Replace the "payload" field of a "packet_info" structure with "len" and
"captured_len" fields, which contain the total packet length and total
captured packet length (including all headers) at the current protocol
layer (i.e., if a given layer has a length field, and that length field
says its shorter than the length we got from the capture, reduce the
"pi.len" and "pi.captured_len" values appropriately).  Those fields can
be used in the future if we add checks to make sure a field we're
extracting from a packet doesn't go past the end of the packet, or past
the captured part of the packet.

Get rid of the additional payload argument to some dissection functions;
use "pi.captured_len - offset" instead.

Have the END_OF_FRAME macro use "pi.captured_len" rather than
"fd->cap_len", so that "dissect the rest of the frame" becomes "dissect
the rest of the packet", and doesn't dissect end-of-frame padding such
as padding added to make an Ethernet frame 60 or more octets long.  (We
might want to rename it END_OF_PACKET; if we ever want to label the
end-of-frame padding for the benefit of people curious what that extra
gunk is, we could have a separate END_OF_FRAME macro that uses
"fd->cap_len".)

Gilbert Ramirez 7bd6c15378 Made the protocol (but not the fields) use the new proto_tree routine,
allowing users to filter on the existence of these protocols. I also
added packet-clip.c to the Nmake makefile.

Gilbert Ramirez 07f42b5b31 Created a new protocol tree implementation and a new display filter
mechanism that is built into ethereal. Wiretap is now used to read all
file formats. Libpcap is used only for capturing.

Gilbert Ramirez 2b86d46d70 Jun-ichiro's IPv6 patch is merged in with ethereal and now uses the new
proto*() functions. The configure script tries to use ipv6 name resolution if
it knows the type of ipv6 stack the user has (this can be avoided with the
--disable-ipv6 switch) Additionally, the configure script now deals with wiretap
better. If the user doesn't want to compile wiretap, the wiretap is never
visited. A few unnecessary #includes were removed from some wiretap files, and
a CPP macro was moved from bpf.c to wtap.h.

Gilbert Ramirez ef3dfe2077 Removed all references to gtk objects from packet*.[ch] files. They now
reference the protocol tree with struct proto_tree and struct proto_item
objects. That way, the packet decoding source code file can be used with
non-gtk packet decoders, like a curses-based ethereal, e.g. I also re-arranged
some of the information in packet.h to more appropriate places (like other
packet-*.[ch] files).

Gilbert Ramirez facb503960 I removed the bit-fields that depended upon gcc's ability to use any type
of variable as a bit field container. ANSI specs only allow unsigned ints
to host bit fields; IBM's C compiler is very ANSI-strict.

Gerald Combs 6ca358948b * Added column formatting functionality.
* Added check_col(), add_col_str() and add_col_fmt() to replace references
  to ft->win_info.
* Added column prefs handling code.

Gilbert Ramirez fcb4c78a6a A lengthy patch to add the wiretap library. Wiretap is not used by default
because it is still in its infancy, but it can be compiled in optionally.
The library exists in its own subdirectory ethereal/wiretap. This patch also
edits all the packet-*.c files to remove the #include <pcap.h> line which is
unnecessary in these files. In the ethereal code, file.c is the most heavily
modified with #ifdef WITH_WIRETAP lines for the optional library.

Guy Harris 0bb16cb989 Add a "val_to_str()" routine that calls "match_strval()" and, if
it returns NULL, formats the value with the format passed in as
	an argument, and returns a pointer to that static buffer.

	Change several "match_strval()" calls to use "val_to_str()".

	In "dissect_ospf()", use "match_strval()" to look up the packet
	type, and use "Unknown" if it doesn't find a match.
