Attilio Rao cecd8edba5 Remove the suser(9) interface from the kernel. It has been replaced from
years by the priv_check(9) interface and just very few places are left.
Note that compatibility stub with older FreeBSD version
(all above the 8 limit though) are left in order to reduce diffs against
old versions. It is responsibility of the maintainers for any module, if
they think it is the case, to axe out such cases.

This patch breaks KPI so __FreeBSD_version will be bumped into a later
commit.

This patch needs to be credited 50-50 with rwatson@ as he found time to
explain me how the priv_check() works in detail and to review patches.

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.
