Guy Harris df1a7250cf Get rid of some unnecessary variables.

Guy Harris a7cc3d8a4f Don't use temporary buffers for strings; use the data in the packet
buffer directly.

Don't use "strlen()" to determine how much Telnet data there is; we have
the number of bytes of Telnet data in a variable, and using "strlen()"
makes it not correctly handle Telnet data with '\0' in it.

Correctly handle Telnet options we don't know about.

General cleanup.

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 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.
