Gilbert Ramirez ddfa11e870 Create a header file for every packet-*.c file. Prune the packet.h file.
This change allows you to add a new packet-*.c file and not cause a
recompilation of everything that #include's packet.h

Add the plugin_api.[ch] files ot the plugins/Makefile.am packaging list.

Add #define YY_NO_UNPUT 1 to the lex source so that the yyunput symbol
is not defined, squelching a compiler complaint when compiling the generated
C file.

Guy Harris 2461d79698 In "dissect_eth()", update "pi.len" and "pi.captured_len" regardless of
whether we're building a protocol tree or not.

Make "dissect_eth()" use "BYTES_ARE_IN_FRAME()" to see if we have a full
Ethernet header - it can be called with a non-zero offset, if Ethernet
frames are encapsulated inside other frames (e.g., ATM LANE).

Make capture routines take an "offset" argument if the corresponding
dissect routine takes one (for symmetry, and for Cisco ISL or any other
protocol that encapsulates Ethernet or Token-Ring frames inside other
frames).

Pass the frame lengths to capture routines via the "pi" structure,
rather than as an in-line argument, so that they can macros such as
"BYTES_ARE_IN_FRAME()" the way the corresponding dissect routines do.

Make capture routines update "pi.len" and "pi.captured_len" the same way
the corresponding diseect routines do, if the capture routines then call
other capture routines.

Make "capture_vlan()" count as "other" frames that are too short, the
way other capture routines do.

Guy Harris a7aba0a288 Replace the ETT_ "enum" members, declared in "packet.h", with
dynamically-assigned "ett_" integer values, assigned by
"proto_register_subtree_array()"; this:

	obviates the need to update "packet.h" whenever you add a new
	subtree type - you only have to add a call to
	"proto_register_subtree_array()" to a "register" routine and an
	array of pointers to "ett_", if they're not already there, and
	add a pointer to the new "ett_" variable to the array, if they
	are there;

	would allow run-time-loaded dissectors to allocate subtree types
	when they're loaded.

Gilbert Ramirez bacb9d5bae New proto_tree header_field_info stuff. Header_field_infos now contain
the base for numbers to be displayed in, bitmasks for bitfields, and blurbs
(which are one or two sentences describing the field).

proto_tree_add*() routines now automatically handle bitfields. You tell
it which header field you are adding, and just pass it the value of the
entire field, and the proto_tree routines will do the masking and shifting
for you.

This means that bitfields are more naturally filtered via dfilter now.

Added Phil Techau's support for signed integers in dfilters/proto_tree.

Added the beginning of the SNA dissector. It's not complete, but I'm
committing it now because it has example after example of how to use
bitfields with the new header_field_info struct and proto_tree routines.
It was the impetus to change how header_field_info works.

Guy Harris 7348611bcb Rename BSD_AF_INET6_OPENBSD to BSD_AF_INET6_BSD, as
1) OpenBSD and NetBSD might use the same value;

	2) BSD/OS uses the same value;

so maybe FreeBSD is the only outlier.

Guy Harris 63a69a5cca FreeBSD and OpenBSD both use 23 for AF_IPX (that may have been in
4.4-Lite), but they use different values for AF_INET6; define and handle
both of them.

Add AF_ISO as well.

Guy Harris ee39938f67 DLT_NULL, from "libpcap", means different things on different platforms
and in different capture files; throw in some heuristics to try to
figure out whether the 4-byte header is:

	1) PPP-over-HDLC (some version of ISDN4BSD?);

	2) big-endian AF_ value (BSD on big-endian platforms);

	3) little-endian AF_ value (BSD on little-endian platforms);

	4) two octets of 0 followed by an Ethernet type (Linux, at least
	   on little-endian platforms, as mutated by "libpcap").

Make a separate Wiretap encapsulation type, WTAP_ENCAP_NULL,
corresponding to DLT_NULL.

Have the PPP code dissect the frame if it's PPP-over-HDLC, and have
"ethertype()" dissect the Ethernet type and the rest of the packet if
it's a Linux-style header; dissect it ourselves only if it's an AF_
value.

Have Wiretap impose a maximum packet size of 65535 bytes, so that it
fails more gracefully when handed a corrupt "libpcap" capture file
(other capture file formats with more than a 16-bit capture length
field, if any, will have that check added later), and put that size in
"wtap.h" and have Ethereal use it as its notion of a maximum packet
size.

Have Ethereal put up a "this file appears to be damaged or corrupt"
message box if Wiretap returns a WTAP_ERR_BAD_RECORD error when opening
or reading a capture file.

Include loopback interfaces in the list of interfaces offered by the
"Capture" dialog box, but put them at the end of the list so that it
doesn't default to a loopback interface unless there are no other
interfaces.  Also, don't require that an interface in the list have an
IP address associated with it, and only put one entry in the list for a
given interface (SIOCGIFCONF returns one entry per interface *address*,
not per *interface* - and even if you were to use only IP addresses, an
interface could conceivably have more than one IP address).

Exclusively use Wiretap encapsulation types internally, even when
capturing; don't use DLT_ types.

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 601c52f0fb Added support for compiling on win32 with Visual C and 'nmake'. It compiles,
but does not link. Perhaps someone who understands the MS tools can help
out. I made it link a few months ago, but with different version of glib/gtk+.
I can't remember how I made it link.

Most of the compatibility issues were resolved with adding
#ifdef HAVE_UNISTD_H the the source code. Please be sure to add this to all
future code.

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 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 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.
