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 0ba3e2b233 Register a "llc.dsap" dissector table for 802.2 LLC, and have dissectors
for protocols that run inside 802.2 LLC register themselves with it
using "dissector_add()".

Make various dissectors static if they can be, and remove from header
files declarations of those dissectors.

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().

Guy Harris cfb98c14c4 Get rid of the include of "util.h" that some dissectors do - it's not
necessary.

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 73729dd8b8 The abbreviation for a protocol is generally all-lower-case, as it's
used as a display filter to match all packets that contain data for that
protocol.
