This clarifies these functions' behavior when the non-control data is
empty but there is a control data present.

It also makes clear the difference between Sendmsg, SendmsgN, and
SendmsgBuffers, and between Recvmsg and RecvmsgBuffers.

The current code has continued to work on OpenBSD, since it has been using
syscall(2) via libc. However, the system call numbers are still hardcoded in
golang.org/x/sys/unix. Various system call changes have been made in OpenBSD,
resulting in changes to the system call numbers and arguments, which now
fail when this package is used.

Switch to calling various system calls directly via libc, rather than calling
via libc using syscall(2).

Unfortunately, this will no longer work on upstream Go since the changes
needed to convert it to libc are still blocked pending review. This means
that we're in a less than ideal situation where upstream Go openbsd/mips64
does not work on any supported OpenBSD release (in fact has not since
OpenBSD 6.8, which was EOL over a year ago), however golang.org/x/sys/unix
is now unusable with the Go package that ships with supported releases via
OpenBSD ports. It would seem that being able to actually use Go software on
a supported OpenBSD release trumps maintaining compatibility with the
unusable upstream Go source.

NetBSD has both struct uvmexp (used internally) and struct uvmexp_sysctl
(preferred for interfacing from user code). Expose the latter as type
Uvmexp with the same interface as on OpenBSD.

I am not sure if it makes sense to even have a name parameter for
SysctlUvmexp, since the only valid value can be "vm.uvmext2".
