kamil 997c4cdc97 sysctl: Add indirection of symbols to remove clash with sanitizers
Add indirection and symbol renaming under MKSANITIZER for the linked in
version of sysctlbyname and sysctlgetmibinfo.

kre c576beb79a kern.boottime was changed from a struct timeval to a struct timespec
in January 2009 (the Christos' time merge, when time_t went to 64 bits).

sysctl needs to catch up.   (So do other progs, which will happen, eventually,
but most of them are unaffected in any practical way.)

If you are running a system (NetBSD 6 or later) without this change, try
	sysctl -nn kern.boottime
and marvel at the result (in theory, seconds.microseconds) most
probably being something like:
	jinx$ sysctl -nn kern.boottime
	1540801874.999995564
(There is a 1 in 1000 chance your system will have booted
in the interval [0 , 999999] nanoseconds after some second,
in which case this will not be observed.   You should get
(almost) the same value after this change - just now it is as
it should be (there should now always be 9 digits after the '.').

On the other hand, if you're on a big-endian 64 bit host (running
64 bit sysctl) you would have always seen 0 for the microseconds field.
That should be fixed by this.

In sysctl(7) also document what we mean by "the time the system booted".

dholland 05ce5c4223 Apply patch from PR 43587, mostly from martin and kre. When writing a
sysctl variable using ?= fails with EPERM, don't print an error
message.

Ideally setting a sysctl to the same value it already has should also
not fail regardless of permissions, but this would need to be done in
the kernel.

pavel edab74570a Move the description of sysctl MIBs from sysctl.3 to a new manual page
sysctl.7. Remove the list of MIBs from sysctl.8 so we don't have to
maintain duplicate information, as proposed by YAMAMOTO Takashi on
tech-userlevel. Also remove references to header files from sysctl.8.

The numeric constants remain documented, they are still needed in some
cases. See the discussion on tech-userlevel. ("mib list in sysctl.8")

OK by YAMAMOTO Takashi.
