Gilbert Ramirez 57d8e47ad0 Add preference for placement of AH payload, at same level or in subtree.
Move max_len settings in various col_* functions outside of loop.

Add 'writable' flag to col_info. check_col() honors its. dissect_packet()
sets it as TRUE. dissect_ah() optionally sets it to FALSE.

Add col_set_writable() function to set the 'writable' flag. Accepts
frame_data arg just like the rest of the column functions. It checks to
make sure fd->cinfo is not NULL.

Gilbert Ramirez 8c27c3d37b Change dissect_ah() so that dissect_ip() doesn't have to make a
special case for it. dissect_ah() is registered with the "ip.proto"
handoff table, and dissect_ah() calls the next dissector using this
same "ip.proto" handoff table.

The old dissect_ah() is kept as dissect_ah_old() since dissect_ipv6()
still uses it. I need to convert some more functions before I can
get rid of dissect_ah_old().

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 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 edd1f26170 Have the IPv6 dissector use the same dissector table as the IPv4
dissector.

Don't dissect the payload of any fragmented IPv6 packet unless it's the
initial fragment (that's what we do for IPv4).

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.

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.

Jun-ichiro itojun Hagino 810a67a6d0 implement ipprotostr() in ipproto.c, which basically does ipprotobynumber()
for ip.ip_p and ip6.ip6_nxt (and other IPv6 header chain).

use val_to_str() as much as possible in dissect_{ipv6,pim,ripng}().

make --disable-zlib a default for netbsd (temporary workaround).

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.

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.
