- Copy stable/10 (r259064) to releng/10.0 as part of the
10.0-RELEASE cycle.
- Update __FreeBSD_version [1]
- Set branch name to -RC1

[1] 10.0-CURRENT __FreeBSD_version value ended at '55', so
start releng/10.0 at '100' so the branch is started with
a value ending in zero.

Whitespace nit

Prepare for the removal of set_rcvar() by changing the rcvar=
assignments to the literal values it would have returned.

The concept of set_rcvar() was nice in theory, but the forks
it creates are a drag on the startup process, which is especially
noticeable on slower systems, such as embedded ones.

During the discussion on freebsd-rc@ a preference was expressed for
using ${name}_enable instead of the literal values. However the
code portability concept doesn't really apply since there are so
many other places where the literal name has to be searched for
and replaced. Also, using the literal value is also a tiny bit
faster than dereferencing the variables, and every little bit helps.

Introduce to rc.subr get_pidfile_from_conf(). It does just what it sounds
like, determines the path to a pid file as it is specified in a conf file.

Use the new feature for rc.d/named and rc.d/devd, the 2 services in the
base that list their pid files in their conf files.

Remove the now-obsolete named_pidfile, and warn users if they have it set.

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.

Add the shutdown KEYWORD to those scripts that start persistent services
to allow them to do a "clean" shutdown.

I purposely avoided making changes to network-related stuff since the
system shutting down is pretty conclusive, and there may be complicated
dependencies on the network that I would rather not try to unravel.

I also skipped kerberos-related stuff for the reasons above, and
because I have no way to test it.

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

network_ipv6 also does some interface configuration so require it to run
before starting devd so they don't trip over each other.

PR: conf/103428

Announce all interfaces to devd on attach/detach. This adds a new devctl
notification so all interfaces including pseudo are reported. When netif
creates the clones at startup devctl_disable has not been turned off yet so the
interfaces will not be initialised twice, enforce this by adding an explicit
order between rc.d/netif and rc.d/devd.

This change allows actions to taken in userland when an interface is cloned
and the pseudo interface will be automatically configured if a ifconfig_<int>=""
line exists in rc.conf.

Use ${name} in pathnames where appropriate.
The sendmail script already was on this way,
but it didn't reach the end of it yet.

Remove the requirement for the FreeBSD keyword as it no longer

Mark scripts as not usable inside a jail by adding keyword 'nojail'.

Start devd after the networking stuff, but before we mount the
critical remote systems. This lets us run commands from devd that
aren't on the / partition. This also means we can remove some kludges
from the networking startup that I added a while ago that caused other
problems.

There's still a race in starting devd that needs to be fixed in devd
so that things present at boot will be configured by the time devd
does daemon(). That race will be fixed later.

Purely cosmetic change.
The # PROVIDE line should precede the # REQUIRE line.

Do not unconditionally load the configuration files for the RCNG case.
Instead, load them as part of the rc.d system. This allows us to prioritize
the initidiskless script so it runs before the configuration files are loaded
and allows us to get rid of the exit 2 hack in /etc/rc. The exit 2 never
worked anyway since it did not unset the prior configuration, causing the
diskless code to not operate properly.

Do a major cleanup and revamping of the diskless code for RCNG. This will
be backported to the non-RCNG scripts as well as -stable.

Two fixes for devd:
1) Move devd to the start of the head of the boot process rather than the end.
2) Disable devctl if devd is disabled.

Add devd to the mix. It should run basically last at this point.
