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.) svn path=/trunk/; revision=12910
