sys/compat: Memset zero before copyout.

Just in case of uninitialized padding which would lead to kernel
stack disclosure.  If the compiler can prove the memset redundant
then it can optimize it away; otherwise better safe than sorry.

Merge changes from current as of 20200406

Sync with head.

Remove explicit calls to the sysctl setup routines, since this is now
handled by the module infrastructure.

- Eliminate the global "boottime" variable, which was being accessed
  without any synchronization against changes by e.g. clock_settime().
- Replace with new getbinboottime() / getnanoboottime() / getmicroboottime()
  functions (naming mirrors that of other time access functions in kern_tc.c).
  It returns the (maybe-converted) value of timebasebin, which also tracks
  our estimate of when the system was booted (i.e. the legacy "boottime" was
  redundant).

XXX There needs to be a lockless synchronization mechanism for reading
timebasebin, but this is a problem in kern_tc.c that pre-existed these
"boottime" changes.  At least now the problem is centralized in one location.

Zero ntptimeval50 too to prevent 4-byte kernel stack disclosure.

From Thomas Barabosch of Fraunhofer FKIE.

XXX pullup-7, pullup-8 (along with rev. 1.60 of kern_ntptime.c)

#include "opt_compat_netbsd.h" for all sources that provide compat code.

Remove duplicate syscall package entry for ntp_gettime30.  Duplicate
entries cause a panic when disestablishing, since when it looks at the
second entry it finds that the entrypoint doesn't match what's in the
package (it's alrady been reverted to sys_nosys() by the first entry.)

Initial implementation of sys/kern/kern_stup.c as discussed on tech-kern

For now, we only handle the dev/ccd and NTP needs;  more to follow.

Initial pass at a COMPAT_50 module.  More to come.

merge to -current.

Instead of calling clockctl_ioctl directly, lookup the cdevsw and
call its d_ioctl function.  This should fix an undefined reference to
`clockctlioctl' when you build a kernel that has COMPAT_50 but does not
have pseudo-device clockctl.

Provide a COMPAT_50 version of the CLOCKCTL_NTP_ADJTIME ioctl.
When time_t was changed from 32 to 64 bits, this ioctl's number
was changed from _IOWR('C', 0x4, struct clockctl_ntp_adjtime)
to _IOWR('C', 0x8, struct clockctl_ntp_adjtime), but the data
structure did not change, so all the compat code has to do is
change the number and try again.

-fix internal use of sigwaitinfo(2) by sigwait(3): The former returns
 the signal number now, as required by POSIX. The latter should just
 return 0 on success. Fixes a mysql problem reported by Kurt Schreiner.
-document the new behavior of sigwaitinfo and sigtimedwait
-retain non-POSIX behavior for NetBSD-5 binary compatibility -- the fix
 would likely not be polled into the .0-branches, and having 5.0.x and
 5.x behave differently would be confusing. Besides that, it was
 documented in the manpage all the time.

- Use cached curlwp->l_fd, instead of p->p_fd.
- Inline selscan/pollscan.
