"data source" has a name and a top-level tvbuff, and frames can have a
list of data sources associated with them.
Use the tvbuff pointer to determine which data source is the data source
for a given field; this means we don't have to worry about multiple data
sources with the same name - the only thing the name does is label the
notebook tab for the display of the data source, and label the hex dump
of the data source in print/Tethereal output.
Clean up a bunch of things discovered in the process of doing the above.

Don't add "-I" flags to search "epan", as that's no longer necessary

Put a hash-table of "interesting" fields in the per-proto-tree data.
The dfilter code records which fields/protocols are "interesting" (by which
I mean, their value or existence is checked). Thus, the proto_tree routines
can create special arrays of field_info*'s that are ready for the dfilter
engine to use during a filter operation.
Also store the "proto_tree_is_visible" boolean, renamed "visible", in
the per-proto-tree data.
Move epan_dissect_t to its own header file to make #include dependencies
easier to handle.
Provide epan_dissect_fill_in_columns(), which accepts just the epan_dissect_t*
as an argument.
epan_dissect_new() needs to be followed by epan_dissect_run() for the
dissection to actually take place. Between those two calls,
epan_dissect_prime_dfilter() can be run 0, 1, or multiple times in order to
prime the empty proto_tree with the "intersesting" fields from the dfilter_t.

structure to the "packet_info" structure; only stuff that's permanently
stored with each frame should be in the "frame_data" structure, and the
"column_info" structure is not guaranteed to hold the column values for
that frame at all times - it was only in the "frame_data" structure so
that it could be passed to dissectors, and, as all dissectors are now
passed a pointer to a "packet_info" structure, it could just as well be
put in the "packet_info" structure.
That saves memory, by shrinking the "frame_data" structure (there's one
of those per frame), and also lets us clean up the code a bit.

binary is being run, the "manuf" file will be there, and you can put
other data files there as well, if necessary.
Do the same with plugins, except that, if there's no
"plugins\\{version}" subdirectory of that directory, fall back on the
default installation directory, so you at least have a place where you
can put plugins for use by build-tree binaries. (Should we, instead,
have the Windows build procedure create a subdirectory of the "plugins"
source directory, with the plugin version number as its name, and copy
the plugins there, so you'd use the build-tree plugin binaries?)

"top-level" dissectors that libepan-users call, instead of dissect_packet().
The epan_dissect_t holds the tvbuff after dissection so that the tvbuff's
memory is not cleared until after the proto_tree is freed. (I might stuff
the proto_tree into the epan_dissect_t, too).
What remains of dissect_packet() in packet.c handles the tvbuff initialiation.
The real meat of dissect_packet() is now in dissect_frame(), in packet-frame.c
This means that "packet.c" is no longer a dissector, os it is no longer
passed to make-reg-dotc.
Once dissect_fddi() gets two wrapper functions (dissect_fddi_swapped()
and dissect_fddi_nonswapped()), the a dissector handoff routine could
be used instead of the switch statement in dissect_frame(). I'd register
a field like "wtap.encap"

may be redrawing a packet window that displays a frame other than the
current frame; give it arguments to specify the raw frame data and
"frame_data" structure for the frame.
This requires that each packet window have, associated with it, a
pointer to the "frame_data" structure; that replaces the "cap_len" and
"encoding" fields in a "PacketWinData" structure, as those are just
copies of fields from the frame's "frame_data" structure.
"packet_hex_print()" needn't be passed both the start and length values
from a "field_info" structure - just pass it a pointer to that
structure, or NULL for "no field is selected in the packet". It also
needn't, any longer, be passed the "cap_len" and "flags.encoding" fields
of a "frame_data" structure - just pass it a pointer to that structure.

"cancel", and "delete" methods, give them:
"fetch" - fetch from the notebook tab any values not already
stored in "prefs", and store them there, but doesn't apply them;
"apply" - apply the settings in "prefs";
"destroy" - clean up any windows created from the tab.
As we no longer have "cancel" methods, we don't have per-preference code
to revert preference values; instead, we have the common preference
dialog box code make a copy of all the current preferences, and, when
the "Cancel" button is clicked, free the current preferences and copy
the saved preferences to it, and apply the preferences.
Add an "Apply" button to the preference dialog box, which applies the
current preferences without closing the dialog box.
Treat a request to delete the preferences dialog box as equivalent to
clicking "Cancel".
Have a "remember_ptree_widget()" routine to remember all protocol tree

out of "main.c" to "proto_draw.c", as it's not used by anything in
"main.c", but is used by stuff in "proto_draw.c".

tree widgets. Also make it something we can set on the fly for the

explicitly; the right thing to do was to have
"remember_scrolled_window()" catch the "destroy" signal on the scrolled

track of the windows they have and forget them when they're destroyed.

there's no need to keep it around in memory - when the frame data is
read in when handing a frame, read in the information, if any, necessary
to reconstruct the frame header, and reconstruct it. This saves some
memory.
This requires that the seek-and-read function be implemented inside
Wiretap, and that the Wiretap handle remain open even after we've
finished reading the file sequentially.
This also points out that we can't really do X.25-over-Ethernet
correctly, as we don't know where the direction (DTE->DCE or DCE->DTE)
flag is stored; it's not clear how the Ethernet type 0x0805 for X.25
Layer 3 is supposed to be handled in any case. We eliminate
X.25-over-Ethernet support (until we find out what we're supposed to
do).

doing something that requires that the text for protocol tree entries be
generated, i.e.
1) initialize it to FALSE;
2) have every routine that sets it clear it when it's done;
3) when printing packets, set it to TRUE only if we're not just
printing packet summary lines;
and then get rid of settings to FALSE made unnecessary as a result of
those changes.
This makes sure it's not set when it doesn't have to be (which causes
the protocol tree code to format the text when it doesn't have to,
wasting CPU time).

which means we're already doing a "do something to the last row in the
packet list" operation on every frame we add to the list, so adding a
call to "gtk_clist_set_row_data()" won't make matters worse.
In addition, we already set one column in a row on a "change time
format" operation, so finding the row for a frame by calling
"gtk_clist_find_row_from_data()" doesn't turn a constant-time operation
into a linear-time operation, it just cranks the proportionality
constant up - it was quadratic before, alas, and it's still quadratic.
Adding calls to "gtk_clist_find_row_from_data()" to the "Find Frame" and
"Go To Frame" code does add an extra linear operation there, but those
operations shouldn't be common - and "Go To Frame", going to the last
frame on an ~100,000-frame big capture file, was quick, at least on my
450 MHz Pentium II machine, so maybe it won't be too bad.
And "select_packet()" either has to search the frame table for the frame
with the specified row number, or has to call "gtk_clist_get_row_data()"
to do that - the first is linear in the position of the frame in the
frame table, and the latter is linear in its position in the CList, and
the latter is less than or equal to the former, so the only thing making
it worse would be a change in the proportionality constant.
So it probably won't hurt performance by much.
Furthermore, if we add the ability to sort the display on an arbitrary
column, or to delete frames from the display - both of which are in the
wish list - storing the row number of the frame in the "frame_data"
structure won't necessarily work, as the row number can change out from
under us.
Therefore, reinstate the old way of doing things, where we associate
with each row a pointer to the "frame_data" structure for the row, using
"gtk_clist_set_row_data()".
