salo b0b7590bc7 Add support for running multi-user in a chroot() environment. 
How it works:

- after successful execution of /etc/rc, check the value of "init.root"
  sysctl node, if it's different than "/", chroot() into its value and run
  /etc/rc inside the chroot(),

- in single-user, return back to the original / file system.

Allows running with / file system on e.g., cgd(4), vnd(4) or ccd(4) volumes.

Idea first discussed with Matt Thomas, implemented by Jachym Holecek <freza
(at) liberouter.org> with some nitpicks by me.  Successfully used by me for
almost a year with / on a cgd(4) volume (for more information about the setup
check ftp://ftp.NetBSD.org/pub/NetBSD/misc/salo/init-chroot/ ).

chris 4727225848 Fix case where argv wasn't returned or freed. 
This fixes Coverity CID 2023.

While here also return NULL if the malloc fails.

elad 03e754fd4d The securelevel does not affect whether Veriexec's tables can be modified; 
this is now controlled by Veriexec's strict level.

dsl 920dff4b7c If /dev/constty exists, use it instead of /dev/console for single user shell. 
I'm not 100% certain it should call login_tty() for anything else.

dsl 58915e2274 If /dev/MAKEDEV is a symlink then preserve the symlink in the mfs /dev. 
If /dev/MAKEDEV doesn't exist then try to run /etc/MAKEDEV instead.
Use the (new) '-n inodes' option to mount_mfs and base the size on the number
of inodes and the size of the MAKEDEV script.

lukem b96069c077 Always compile in support for attempting to obtain the major device 
number of the console from sysctl("machdep.console_device"), rather
than making in optional on the (unused) #ifdef DEBUG.
Certain platforms do not have the console at makedev(0,0) (including
many arm32 and some sh3 platforms), so the "mfs MAKEDEV" hack would
have failed on those.

Noted in private discussion with Quentin Barnes.

lukem 35c2bddeea If RESCUEDIR is defined, use that as an alternate path to sh and mount_mfs,

assumption that reboot(8) is in the middle of taking the system down.
This fixes `panic: init died' from sysinst.
