Add a new tap flag to indicate that a tap listener is just a "dissector helper",
that is, a tap which is used by a dissector to help it do its dissection but
does not, itself, require dissection.
Use this new flag in the dissectors which register taps.
Remove the (now-unused) have_tap_listeners() function.

a protocol tree;
the column values.
This includes stats-tree listeners.
Have the routines to build the packet list, and to retap packets, honor
those requirements. This means that cf_retap_packets() no longer needs
an argument to specify whether to construct the column values or not, so
get rid of that argument.
This also means that there's no need for a tap to have a fake filter
to ensure that the protocol tree will be built, so don't set up a fake
"frame" filter.
While we're at it, clean up some cases where "no filter" was represented
as a null string rather than a null pointer.
Have a routine to return an indication of the number of tap listeners
with filters; use that rather than the global num_tap_filters.
Clean up some indentation and some gboolean vs. gint items.

Patch to tap.c which simply returns the same tap_id if the register_tap is called twice with the same name - I can't see any downside to this.
( Needed for the gsm_a split -Anders).

tell if a specific tap id is currently listening for data.
This complements the function have_tap_listeners(), which checks
to see if any tap is currently listening.

This function can be called from a dissector to fetch (if any) tapped data from a tap.
This can offer an alternative method of passing data between different dissectors much cleaner than the pinfo pollition and private_data design mistake.
The SMB2 dissector uses this method to extract vital data such as Account_Name from the ntlmssp dissector (that is 3 leveld down from smb2)

and "Statistics" menu items into "stat.h" and "stat.c", to separate them
from the core tapping APIs. A tap could conceivably not register as a
"-z" command-line argument or "Statistics" menu item, and a stat could
conceivably not be implemented as a tap, and dissectors that implement
tapping points don't need the UI-related stuff from "stat.h", they just
want the tap-related stuff in <epan/tap.h>.

_U_-ify some unused arguments, rather than assigning them to themselves.
Un-constify one variable that gets assigned a mallocated pointer.
Clean up indentation.

it's used to register a callback for a tap listener invoked if the
specified command line argument is specified to the "-z" flag.
Move it, along with routines to:
look up a "-z" argument in the table constructed by
"register_tap_listener_cmd_arg()" and either save the full
argument to "-z" and the corresponding listener if it's found or
return a failure indication if it isn't;
list the available tap listeners;
call the "init" routines for the tap listeners saved in the
table above;
and have Ethereal and Tethereal use those routines.

Fix up some const-pointer-to-non-const-pointer, and
function-pointer-to-void-*, conversions.
Fix some comments.
