Guy Harris 252d55d80f For each column, have both a buffer into which strings for that column
can be put, and a pointer to the string for the column, which might or
might not point to that buffer.

Add a routine "col_set_str()", which sets the string for the column to
the string passed to it as an argument; it should only be handed a
static string (a string constant would be ideal).  It doesn't do any
copying, so it's faster than "col_add_str()".

Make the routines that append to columns check whether the pointer to
the string for the column points to the buffer for the column and, if
not, copy the string for the column to the buffer for the column so that
you can append to it (so you can use "col_set_str()" and then use
"col_append_str()" or "col_append_fstr()").

Convert a bunch of "col_add_str()" calls that take a string constant as
an argument to "col_set_str()" calls.

Convert some "col_add_fstr()" calls that take a string constant as the
only argument - i.e., the format string doesn't have any "%" slots into
which to put strings for subsequent arguments to "col_set_str()" calls
(those calls are just like "col_add_str()" calls).

Replace an END_OF_FRAME reference in a tvbuffified dissector with a
"tvb_length(tvb)" call.

Guy Harris c8196a1d1c Tvbuffify the IP, ICMP, TCP, UDP, OSI CLNP, OSI COTP, OSI CLTP, and OSI
ESIS dissectors.

Register the IP dissector and have dissectors that call it directly
(rather than through a port table) call it through a handle.

Add a routine "tvb_set_reported_length()" which a dissector can use if
it was handed a tvbuff that contains more data than is actually in its
part of the packet - for example, handing a padded Ethernet frame to IP;
the routine sets the reported length of the tvbuff (and also adjusts the
actual length, as appropriate).  Then use it in IP.

Given that, "ethertype()" can determine how much of the Ethernet frame
was actually part of an IP datagram (and can do the same for other
protocols under Ethernet that use "tvb_set_reported_length()"; have it
return the actual length, and have "dissect_eth()" and "dissect_vlan()"
use that to mark trailer data in Ethernet II frames as well as in 802.3
frames.

Guy Harris 6093369044 Make "packet-clip.c", "packet-raw.c", "packet-ppp.c", "packet-tr.c",
"packet-eth.c", and "packet-fddi.c" include the include files that
declare the functions they export, so that the declarationss in the
header files will be checked against the definitions in the source
files.

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.

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.
