Robert Watson c28aedefd8 Rework SPX segment reassembly, which was originally based on our TCP
reassembly but failed to be modernized over time:

- Use queue(9).
- Specifically allocate queue entries of type M_SPXREASSQ to point at
  member mbufs, rather than casting mbuf data to 'spx_q'.
- Maintain the mbuf pointer as part of the queue entry so that we can
  later free the mbuf without using dtom().

This protocol implements IPX/SPX over Ethernet_II frame type 0x8137.
Please note: the SPX implementation may require further work and testing
to insure proper operation.

--- TODO ---

(1) netipx default socket buffer sizes are very small by contemporary
    standards, and should be increased following testing and measurement.

(2) SPX will free the PCB and socket buffer memory on close(), which means
    close() in effects terminates the transfer of any outstanding buffered
    but unsent data.  As with TCP, it should instead grab its own
    reference to the socket so that it is not released, as hold onto it
    until the data transfer is complete.

(3) Raw socket capture of IPX output intercepts packets in the SPX output
    routine in order to feed them back into the raw socket.  This results
    in recursion into the socket code in the transmit path; instead,
    captured packets should be fed into a netisr that reinjects them into
    raw sockets from a new (asynchronous) context.

(4) IPX over IP encapsulation needs work to make it properly MPSAFE.
