#2542 osaf: Divide the safe reboot into two phases

[Anders Widell]

As a simple solution to the problem described in [#2451], we can divide the safe reboot in the opensaf_reboot script into two phases: in the first phase we stop important OpenSAF services (especially IMM), and in the second phase we reboot the nodes. The full solution described in [#2451] can be implemented later as part of the enhanced cluster management.

clm: Call opensaf_reboot_prepare() so that fallback reboot will work [#2542]

The fallback reboot mechanism requires write permission to the SysRq proc
interface, so we must call opensaf_reboot_prepare() before daemonize() to make
sure it works properly.

base: Use fallback reboot when safe reboot fails [#2542]

If the shutdown -r command fails, either by returning an error code immediately,
or by not completing the reboot within one minute, we will call the failfast
reboot mechanism to make sure the node reboots.

osaf: Divide the safe reboot into two phases [#2542]

Divide the safe reboot in the opensaf_reboot script into two phases: in the
first phase we stop important OpenSAF services (currently only IMM), and in the
second phase we reboot the nodes.
