Manage ASCII trace files for device models.
Handling ascii trace files is a common operation for ns-3 devices. It is useful to provide a common base class for dealing with these ops.

Create and initialize an output stream object we'll use to write the traced bits.
One of the common issues users run into when trying to use tracing in ns-3 is actually a design decision made in the C++ stream library. It is not widely known that copy and assignment of iostreams is forbidden by std::basic_ios<>. This is because it is not possible to predict the semantics of the stream desired by a user.
The tempting ns-3 idiom when tracing to a file is to create a bound callback with an ofstream as the bound object. Unfortunately, this implies a copy construction in order to get the ofstream object into the callback. This operation, as mentioned above, is forbidden by the STL. You could use a global ostream and pass a pointer to it, but that is pretty ugly. You could create an ostream on the stack and pass a pointer to it, but you may run into object lifetime issues. Ns-3 has a nice reference counted object that can solve the problem so we use one of those to carry the stream around and deal with the lifetime issues.

Basic Dequeue default trace sink.
When a packet has been sent to a device for transmission, the device is expected to place the packet onto a transmit queue even if it does not have to delay the packet at all. The device removes the packet from the transmit queue when the packet is ready to send, and this dequeue will fire a corresponding event. This event will eventually translate into a '-' operation in the trace file.
This is typically implemented by hooking the "TxQueue/Dequeue" trace hook in the device (actually the Queue in the device).

Basic Drop default trace sink.
When a packet has been sent to a device for transmission, the device is expected to place the packet onto a transmit queue. If this queue is full the packet will be dropped. The device is expected to trigger an event to indicate that an outbound packet is being dropped. This event will eventually translate into a 'd' operation in the trace file.
This is typically implemented by hooking the "TxQueue/Drop" trace hook in the device (actually the Queue in the device).

Basic Enqueue default trace sink.
When a packet has been sent to a device for transmission, the device is expected to place the packet onto a transmit queue even if it does not have to delay the packet at all, if only to trigger this event. This event will eventually translate into a '+' operation in the trace file.
This is typically implemented by hooking the "TxQueue/Enqueue" trace hook in the device (actually the Queue in the device).
