Fix broken dependency with routed when MK_ROUTED != no

Remove routed as a requirement in NETWORKING, and put it in routed as a BEFORE
requirement instead

Remove mroute6d rc script

It is directly available via ports (pim6dd which provides the needed rc script)

Reported by: lme

Enhance rc.d/netwait script to wait for late-attaching interfaces such as
USB NICs.

USB network hardware may not be enumerated and available when the rc.d
networking scripts run. Eventually the USB attachment completes and devd
events cause the network initialization to happen, but by then other rc.d
scripts have already failed, because services which depend on NETWORKING
(such as mountcritremote) may end up running before the network is actually
ready.

There is an existing netwait script, but because it is dependent on
NETWORKING it runs too late to prevent failure of some other rc
scripts. This change flips the order so that NETWORKING depends on netwait,
and netwait now depends on devd and routing (the former is needed to make
interfaces appear, and the latter is needed to run the ping tests in
netwait).

The netwait script used to be oriented primarily towards "as soon as any
host is reachable the network is fully functional", so you gave it a list of
IPs to try and you could optionally name an interface and it would wait for
carrier on that interface. That functionality still works the same, but now
you can provide a list of interfaces to wait for and it waits until each one
of them is available. The ping logic still completes as soon as the first IP
on the list responds.

These changes were submitted by Brenden Molloy <brendan+freebsd@bbqsrc.net>
in PR 205186, and lightly modified by me to allow a list of interfaces
instead of just one.

Unbreak rcorder when MK_UNBOUND == no by moving local_unbound from REQUIRE:
in NETWORKING to BEFORE: in the script

Remove etc/rc.d/mrouted

mrouted has been available in ports for the last 8 years as net/mrouted . An
equivalent rc.d script has been present in the port.

Remove all corresponding variables from etc/defaults/rc.conf

Relnotes: yes

Renove faith(4) and faithd(8) from base. It looks like industry
have chosen different (and more traditional) stateless/statuful
NAT64 as translation mechanism. Last non-trivial commits to both
faith(4) and faithd(8) happened more than 12 years ago, so I assume
it is time to drop RFC3142 in FreeBSD.

No objections from: net@

Forgotten in r255825: NETWORKING requires local_unbound.

Add etc/rc.d/static_ndp, analogous to etc/rc.d/static_arp.
Make sure that static ARP and NDP bindings are set before NETWORKING.

As static_ndp is based on static_arp, pass copyright to the project with
permission of the original author (delphij@).

Use REQUIRE: line to reorder rc.d/bridge instead of BEFORE: line.

Integrate rc.d/network_ipv6 into rc.d/netif:

- Add rc.d/stf and rc.d/faith for stf(4) and faith(4).
- Remove rc.d/auto_linklocal and rc.d/network_ipv6.
- Move rc.d/sysctl to just before FILESYSTEMS because rc.d/netif
depends on some sysctl variables.

Reverse the effect of r193198 for pf and ipfw which will once again
allow them to start after netif. There were too many problems reported
with this change in the short period of time that it lived in HEAD, and
we are too late in the release cycle to properly shake it out.

IMO the issue of having the firewalls up before the network is still a
valid concern, particularly for pf whose default state is wide open.
However properly solving this issue is going to take some investment
on the part of the people who actually use those tools.

This is not a strict reversion of all the changes for r193198 since it
also included some simplification of the BEFORE/REQUIRE logic which is
still valid for ipfilter and ip6fw.

As previously discussed, add the svn:executable property to all scripts

Fix the wait for default route change I made a few weeks ago by creating
a new defaultroute script that just does the wait. The previous attempt
created a circular dependency through network_ipv6.

Remove ISDN4BSD (I4B) from HEAD as it is not MPSAFE and
parts relied on the now removed NET_NEEDS_GIANT.
Most of I4B has been disconnected from the build
since July 2007 in HEAD/RELENG_7.

This is what was removed:
- configuration in /etc/isdn
- examples
- man pages
- kernel configuration
- sys/i4b (drivers, layers, include files)
- user space tools
- i4b support from ppp
- further documentation

Remove $NetBSD$ CVS tags. We no longer attempt to synch our rc.d files
with theirs, so this information doesn't need to be in the live file.
Having it in our CVS history is enough.

Finish making resolv ordering deterministic by REQUIRE'ing it here.

Apply "additional TCP options" earlier.

Don't bogusly depend on dhclient. It's now run either by
/etc/rc.d/netif or from devd rather than by the startup scripts.

Transforming "ppp-user" into just "ppp", step 1:
The rcorder(8) condition PROVIDE'd by the script
and REQUIRE'd by the others becomes "ppp".

The ultimate goal of the transformation is to reduce
confusion resulting from the fact that $name has been
"ppp" already.

Remove scripts we don't use from requirement lines. These were
hold-overs from the initial NetBSD import.

Luke Mewburn has indicated that they (NetBSD) are not interested
in keeping the scripts under rc.d in sync with us. So, begin removal
of NetBSD specific stuff (which made our scripts more complicated
than necessary), starting with the NetBSD KEYWORD.

o Hookup rc.d/routing and rc.d/netoptions
o Ensure rc.d/network2 and rc.d/network3 are not automatically run
during boot
o Modify script headers so rcorder(8) can put the two scripts in the
correct sequence.

o Hook the new files up to the build.
o Make sure all the scripts reference rc.d/netif and not rc.d/network1
