Guy Harris 283ce59938 Add routines for adding items to a protocol tree that take arguments of
a particular type, rather than taking a varargs list, along the lines of
the "proto_tree_add_XXX_format()" routines.

Replace most calls to "proto_tree_add_item()" and
"proto_tree_add_item_hidden()" with calls to those routines.

Rename "proto_tree_add_item()" and "proto_tree_add_item_hidden()" to
"proto_tree_add_item_old()" and "proto_tree_add_item_hidden_old()", and
add new "proto_tree_add_item()" and "proto_tree_add_item_hidden()"
routines that don't take the item to be added as an argument - instead,
they fetch the argument from the packet whose tvbuff was handed to them,
from the offset handed to them.

Gilbert Ramirez 40c5ed378f Convert dissect_ppp() and friends to use tvbuffs.
(the ip_tcp_options stuff is still non-tvbuff until I convert ip and tcp).

Add preliminary fix for Linux ISDN ippp devices (similar watch was posted
to ethereal-users, but did not use tvbuffs).

Change packet-raw.c to call capture_ppp()/dissect_ppp() in the case
where the frame starts with FF:03. We had been calling
capture_ip()/dissect_ip() at byte offset 4, but I think this is for
historical reasons of packet-raw.c and packet-ip.c existing before
packet-ppp.c.

Gilbert Ramirez 292e38e2c6 Add tvbuff class.
Add exceptions routines.
Convert proto_tree_add_*() routines to require tvbuff_t* argument.
Convert all dissectors to pass NULL argument ("NullTVB" macro == NULL) as
the tvbuff_t* argument to proto_tree_add_*() routines.

dissect_packet() creates a tvbuff_t, wraps the next dissect call in
a TRY block, will print "Short Frame" on the proto_tree if a BoundsError
exception is caught.

The FDDI dissector is converted to use tvbuff's.

Guy Harris 9aa7670a4e Register an "ip.proto" dissector table for IPv4, and have dissectors for
protocols that run inside IPv4 register themselves with it using
"dissector_add()".

Make various dissectors static if they can be, and get rid of any header
files that no longer contain any information as a result of that change.

Gilbert Ramirez f6e92a9e93 Break proto_tree_add_item_format() into multiple functions:
proto_tree_add_protocol_format()
	proto_tree_add_uint_format()
	proto_tree_add_ipxnet_format()
	proto_tree_add_ipv4_format()
	proto_tree_add_ipv6_format()
	proto_tree_add_bytes_format()
	proto_tree_add_string_format()
	proto_tree_add_ether_format()
	proto_tree_add_time_format()
	proto_tree_add_double_format()
	proto_tree_add_boolean_format()
If using GCC 2.x, we can check the print-format against the variable args
passed in. Regardless of compiler, we can now check at run-time that the
field type passed into the function corresponds to what that function
expects (FT_UINT, FT_BOOLEAN, etc.)

Note that proto_tree_add_protocol_format() does not require a value field,
since the value of a protocol is always NULL. It's more intuitive w/o the
vestigial argument.

Fixed a proto_tree_add_item_format-related bug in packet-isis-hello.c
Fixed a variable usage bug in packet-v120.c. (ett_* was used instead of hf_*)

Checked in Guy's fix for the function declearation for proto_tree_add_text()
and proto_tree_add_notext().

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.

The routing information in a GRE packet is a list of items; dissect all
of them (partially - we don't actually dissect the routing data).

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.

Guy Harris 96e79ab6f8 Add a "BYTES_ARE_IN_FRAME()" macro, to test whether there are a
specified number of bytes of captured data in the frame at the specified
offset, and a "IS_DATA_IN_FRAME()" macro, to test whether there are any
bytes of captured data in the frame at the specified offset, and convert
some bounds checks to use them.

Add a dissector for the Internet Printing Protocol.

Guy Harris f93c76fd10 Convert a bunch of uses of "fd->cap_len" to use "pi.captured_len" (or to
use END_OF_FRAME), so that they don't look at stuff in an IP datagram
past the end of the IP datagram (i.e., frame padding).

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.
