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.

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.

UDP and into the handoff registration routines for the protocols in
question.
Make the dissectors for those protocols static if they're not called
outside the dissector's source file.
Get rid of header files if all they did was declare dissectors that are
now static; remove declarations of now-static dissectors from header
files that do more than just declare the dissector.

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().

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.

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.

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".)
