target_type was only used for the initial hardlink design and
implementation, which is not how it works today.

netinet6: Improve flexibility of receiving Router Advertisement

Convert the sysctl 'net.inet6.ip6.accept_rtadv' to be the default value
of the per-interface flag 'ND6_IFF_ACCEPT_RTADV', making it no longer a
global knob. Now the receiving RA is allowed if ip6_forwarding==0 *and*
'ND6_IFF_ACCEPT_RTADV' is set on that interface.

ndp(8) already supports to toggle the 'ND6_IFF_ACCEPT_RTADV' flag via
the 'accept_rtadv' option.

Add a new per-interface flag 'ND6_IFF_AUTO_LINKLOCAL' and convert the
sysctl 'net.inet6.ip6.auto_linklocal' to be the default value of this
new per-interface flag. This allows to fine control the automatic
link-local address configuration on a per-interface basis.

Update ndp(8) to support to toggle the 'ND6_IFF_AUTO_LINKLOCAL' flag by
adding the 'auto_linklocal' option.

Document the 'IPV6CTL_AUTO_LINKLOCAL' option in the inet6(4) man page.

kernel - Add per-process capability-based restrictions

* This new system allows userland to set capability restrictions which
turns off numerous kernel features and root accesses. These restrictions
are inherited by sub-processes recursively. Once set, restrictions cannot
be removed.

Basic restrictions that mimic an unadorned jail can be enabled without
creating a jail, but generally speaking real security also requires
creating a chrooted filesystem topology, and a jail is still needed
to really segregate processes from each other. If you do so, however,
you can (for example) disable mount/umount and most global root-only
features.

* Add new system calls and a manual page for syscap_get(2) and syscap_set(2)

* Add sys/caps.h

* Add the "setcaps" userland utility and manual page.

* Remove priv.9 and the priv_check infrastructure, replacing it with
a newly designed caps infrastructure.

* The intention is to add path restriction lists and similar features to
improve jailess security in the near future, and to optimize the
priv_check code.

usr.sbin/makefs/hammer2: Support recursive read for "-o R" option

"-o R" option currently creates 0 byte file if a given path is
a directory, as directory inode size is set to 0.

Change this to recursively walk directories, and retrieve directories
and regular files under that directory. Specifying "-o R=/" does
the reverse of what makefs(8) does.

It currently has following limitations.
- Only directory and regular file are supported, other types are ignored.
- Hard links are not ignored, but files are retrieved as different inodes
and link count is not preserved.
- Inode timestamp is not preserved.
- Anything that HAMMER2 and this option support, but underlying
file system doesn't is unsupported.
