This patch adds support for restarting the API socket on SIGHUP, similar
to how SysV init and systemd use SIGUSR1 to restart their FIFO or D-Bus.

This patch adds a rescue (revovery) mode to Finit. Simply add `rescue`
to the kernel cmdline at boot and the following steps at bootstrap will
be skipped:
- Load of services/run/task/etc in /etc/finit.conf + /etc/finit.d/*.conf
- fsck of filesystems in /etc/fstab
- Remount of / to read-write
- Mount of all filesystems in /etc/fstab
- swapon
- A few plugin hooks:
- HOOK_ROOTFS_UP
- HOOK_MOUNT_ERROR
- HOOK_BASEFS_UP
- `runparts DIR`
- /etc/rc.local
Instead of loading /etc/finit.conf and /etc/finit.d/*.conf Finit loads
the file /lib/finit/rescue.conf, which can be overridden by the operator
if needed. If this file is removed (or lost), Finit falls back to start
a simple root shell, without any login.

This change removes a long standing kernel requirement and architectural
mishap in the design of Finit v1. It is no longer necessary to include
CONFIG_SYSVIPC in the kernel to use Finit and its command line tool
initctl. It is also no longer possible to connect to the internals of
PID 1 using shmat(), the initctl tool has already been updated to use
the domain socket API.
