Gleb Smirnoff 6aae3517ed Retire synchronous PPP kernel driver sppp(4).
The last two drivers that required sppp are cp(4) and ce(4).

These devices are still produced and can be purchased
at Cronyx <http://cronyx.ru/hardware/wan.html>.

Since Roman Kurakin <rik@FreeBSD.org> has quit them, they no
longer support FreeBSD officially.  Later they have dropped
support for Linux drivers to.  As of mid-2020 they don't even
have a developer to maintain their Windows driver.  However,
their support verbally told me that they could provide aid to
a FreeBSD developer with documentaion in case if there appears
a new customer for their devices.

These drivers have a feature to not use sppp(4) and create an
interface, but instead expose the device as netgraph(4) node.
Then, you can attach ng_ppp(4) with help of ports/net/mpd5 on
top of the node and get your synchronous PPP.  Alternatively
you can attach ng_frame_relay(4) or ng_cisco(4) for HDLC.
Actually, last time I used cp(4) back in 2004, using netgraph(4)
instead of sppp(4) was already the right way to do.

Thus, remove the sppp(4) related part of the drivers and enable
by default the negraph(4) part.  Further maintenance of these
drivers in the tree shouldn't be a big deal.

While doing that, remove some cruft and enable cp(4) compilation
on amd64.  The ce(4) for some unknown reason marks its internal
DDK functions with __attribute__ fastcall, which most likely is
safe to remove, but without hardware I'm not going to do that, so
ce(4) remains i386-only.
