guestrpc module to handle VMware backdoor port GuestRPC functionality

Convert existing FreeBSD vmware_hvcall function to take a channel
and parameter arguments.

Added vmware_guestrpc_cmd() to send GuestRPC commands to the VMware
hypervisor. The sbuf argument is used for both the command to send
and to store the data to return to the caller.

The following KPIs can be used to get and set FreeBSD-specific guest
information in key/value pairs:
* vmware_guestrpc_set_guestinfo
- set a value into the guestinfo.fbsd.<keyword> key
* vmware_guestrpc_get_guestinfo
- get the value stored in the guestinfo.fbsd.<keyword> key

Complete retire cp(4)

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

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.

Use envvar rather than nonstandard hint. lines

The NOTES files have a bunch of hint lines that are removed when
generating LINT. However, we can achieve the same effect by prepending
each of the lines with 'envvar' so the NOTES files become standard
config(8) files. No functional changes as the sed script to generate
the LINT files filters these either way.

Move sc out of the global file

x86 needs sc, as does sparc64. powerpc doesn't use it by default, but some old
powermac notebooks do not work with vt yet for reasons unknonw. Even so, I've
removed it from powerpc LINT. It's not in daily use there, and the intent is to
100% switch to vt now that it works for that platform to limit support burden.

All the other architectures omit some or all of the screen savers from their
lint config. Move them to the x86 NOTES files and remove the exclusions. This
reduces slightly the number of savers sparc64 compiles, but since they are in
GENERIC, the overage is adequate and if someone reaelly wants to sort them out
in sparc64 they can sweat the details and the testing.
