The inclusion of 0a0f7486413c broke the build with the -DNO_ROOT option.
Specifically, that commit adds some relative paths (with `..`) to METALOG
that make other tools using that log, fail afterwards (tar, makefs...).
It's been argued[1] if this is really something mtree(8) should handle more
graciously. In the meantime, fix the breakage but changing the order in which
the links are created: first in the parent directory, then in the
architecture-specific one.
We keep the architecture-specific directories an the links to the parent
directories. This is something that we might want to change in the future.
This commit is based on a concept patch by avg@.

Disable Duplicate Address Detection in EC2 instances. The networking
configuration in EC2, with IPv6 addresses assigned by DHCPv6 and
host egress filtering, makes "duplicate addresses" impossible.
This speeds up the boot process in EC2 by 2 seconds.

This disables the random (between zero and one seconds) delay before
rtsol and rtsold send a a Router Solicitation packet. This delay is
specified as a SHOULD by RFC 4861 for avoidance of network congestion,
but network speeds have increased enough in the 25 years since this
first appeared (in RFC 1970) that it seems unnecessary as a default
at this point.
This speeds up the FreeBSD boot process by an average of 500 ms.

Add a new ioctl to vt to make it possible to export RGB offsets
set by vt drivers. This is needed to fix colors on X and Mesa
on some machines, especially on modern PowerPC64 BE ones.
With the appropriate changes in SCFB, to use this ioctl to find
out the correct RGB offsets, this fixes wrong colors on Talos II
and Blackbird, when used with their built-in video cards.

VOP_STRATEGY() requires locked vnode. Note that we lock the swap vnode
while pages are busy, but this would only cause real LoR if pages belong
to the swap vnode, which must not be the case for correct use.

Currently agp(4) effectively assumes that only one driver instance
exists, as the generic attach routine attempts to create /dev/agpgart
and triggers a panic if it already exists. Instead, handle this
situation by creating /dev/agpgart<unit> and making /dev/agpgart an
alias of /dev/agpgart0 for compatibility.

Instead of returning 0xffs some controllers, such as Layerscape generate
an external exception when someone attempts to read any register
of config space of a non-existing device other than PCIR_VENDOR.
This causes a kernel panic.
Fix it by bailing during device enumeration if a device vendor register
returns invalid value. (0xffff)
Use this opportunity to replace some hardcoded values with a macro.
I believe that this change won't have any unintended side-effects since
it is safe to assume that vendor == 0xffff -> hdr_type == 0xffff.

Default action for ldconfig is specified as -R AKA 'append', and for
no-args (without options changing default actions), ldconfig should
append empty list of directories to current list. But because the check
was done before options were parsed out, presence of any option turned
off default rescan.
As result, innocently-looked commands like `ldconfig -v' were interpreted
as setting directory hints list to one specified on the command line,
i.e. empty.
