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>.

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.

const pointer (so that we don't get complaints when we make the
tap-specific data argument to "tap_queue_packet()" a const pointer,
allowing dissectors to hand const data to a tap without a complaint), we
should make the tap per-packet function take a const pointer as an
argument as well. Do so.
In some taps, use _U_, or actually use the argument, rather than
sticking in dummy "X = X" assignments to fake use of parameters. (This
means that the tap functions in question no longer have the notion that
they act on a particular static structure wired in.)
