Gilbert Ramirez b2f932c1db Changed the display filter scanner from GLIB's GScanner to lex. The code
as it standed depends on your lex being flex, but that only matters if you're
a developer. The distribution will include the dfilter-scanner.c file, so
that if the user doesn't modify dfilter-scanner.l, he won't need flex to
re-create the *.c file.

The new lex scanner gives me better syntax checking for ether addresses. I
thought I could get by using GScanner, but it simply wasn't powerful enough.

All operands have English-like abbreviations and C-like syntax:
and, && ; or, || ; eq, == ; ne, != ; , etc.

I removed the ETHER_VENDOR type in favor of letting the user use the [x:y]
notation:	ether.src[0:3] == 0:6:29 instead of ether.srcvendor == 00:06:29

I implemented the IPXNET field type; it had been there before, but was
not implemented. I chose to make it use integer values rather than byte
ranges, since an IPX Network is 4 bytes. So a display filter looks like this:
	ipx.srcnet == 0xc0a82c00
rather than this:
	ipx.srcnet == c0:a8:2c:00

I can supposrt the byte-range type IPXNET in the future, very trivially.

I still have more work to do on the parser though. It needs to check ranges
when extracting byte ranges ([x:y]) from packets. And I need to get rid
of those reduce/reduce errors from yacc!

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 0d36ec8de2 Modified the proto_register_field_array usage again. Thanks to Guy's
suggestion, this new method using a static array should use less memory
and be faster. It also has a nice side-effect of making the source-code
more readble, IMHO.

Changed the print routines to look for protocol proto_data instead of
looking at the text label as they did before, hoping that the data hex
dump field item starts with "Data (".

Added the -G keyword to ethereal to make it dump a glossary of display
filter keywords to stdout and exit. This data is then formatted with
the doc/dfilter2pod perl program to pod format, which is combined
with doc/ethereal.pod.template to create doc/ethereal.pod, from which
the ethereal manpage is created. This way we can keep the manpage up-to-date
with a list of fields that can be filtered on.

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 6a971ea03c Found a small bug in how the Token-Ring code tried to be smart and looked
for RIF bytes w/o the source-route bit being set.

Gilbert Ramirez af2bae7723 Changed the Access Control and Frame Control fields in the Token-Ring header
to use the decode_*_bitfield() routines. This needed to happen anyway, but
I finally made the change so that I can figure out how I'm going to handle
bitfield fields in my experiment of changing the implementation of the
protocol tree in ethereal.

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).

Guy Harris 75305346b5 When doing a capture, decode enough of the incoming packets to correctly
update the packet counts and percentages in the dialog box popped up
during a capture, even for non-Ethernet captures.

proper bounds checking. Fixed.

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.

Gerald Combs 2e7e493198 Merged in a _huge_ patch from Guy Harris. It adds a time stap column,
generalizes the column printing code, adds a "frame" tree item to
   the tree view, and fixes a bunch of miscellaneous coding bugs.

Gilbert Ramirez 020b7bfc99 I cleaned up the TR code by using variables that correspond to the TR header
fields. I got rid of a lot of pd[x] type stuff. I also made the TR code
a bit smarter again. With Linux 2.0.x and oltr, the source-route bit is
cleared before we get it. I can now detect more packets that were source-
routed but had their SR bit cleared.
