Add a new shutdown runlevel, Gentoo #224537. Split halt.sh into halt, killprocs, romount and savecache services. The reboot runlevel is removed but mapped to shutdown. The halt script should be moved to the sysvinit package.

# This basically mounts $RC_SVCDIR as a ramdisk.
Rewrite the core parts in C. We now provide librc so other programs can query runlevels, services and state without using bash. We also provide libeinfo so other programs can easily use our informational functions. As such, we have dropped the requirement of using bash as the init script shell. We now use /bin/sh and have strived to make the scripts as portable as possible. Shells that work are bash and dash. busybox works provided you disable s-s-d. If you have WIPE_TMP set to yes in conf.d/bootmisc you should disable find too. zsh and ksh do not work at this time. Networking support is currently being re-vamped also as it was heavily bash array based. As such, a new config format is available like so config_eth0="1.2.3.4/24 5.6.7.8/16" or like so config_eth0="'1.2.3.4 netmask 255.255.255.0' '5.6.7.8 netmask 255.255.0.0'" We will still support the old bash array format provided that /bin/sh IS a link it bash. ChangeLog for baselayout-1 can be found in our SVN repo.

sysinit is now a real runlevel that handles things like udev, dmesg and mounting various bits in /dev and /sys. init.sh JUST mounts /lib/rc/init.d (and /proc for Linux systems) To make development of this easier we now return an empty RC_STRINGLIST instead of a NULL for empty things. If you don't have a udev init script installed, don't reboot your box OR roll back to an older OpenRC version.
