def: centralize definition of default timeout in one place

use #pragma once instead of foo*foo #define guards #pragma once has been "un-deprecated" in gcc since 3.3, and is widely supported in other compilers. I've been using and maintaining (rebasing) this patch for a while now, as it annoyed me to see #ifndef fooblahfoo, etc all over the place, almost arrogant about the annoyance of having to define all these names to perform a commen but neccicary functionality, when a completely superior alternative exists. I havn't sent it till now, cause its kindof a style change, and it is bad voodoo to mess with style that has been established by more established editors. So feel free to lambast me as a crazy bafoon. v2 - preserve externally used headers

manager: Do not handle SIGKILL since we can not This is a minor fix because it's not a major issue, this fix just avoid to get EINVAL error from sigaction(2). There are two signals can not handled at user space, SIGKILL and SIGSTOP even we're PID 1, trying to handle these two signals will get EINVAL error. There are two kinds of systemd instance, running as system manager or user session manager, apparently, the latter is a general user space process which can not handle SIGKILL. The special pid 1 also can not do that refer to kernel/signal.c:do_sigaction(). However, pid 1 is unkillable because the kernel did attach SIGNAL_UNKILLABLE to it at system boot up, refer to init/main.c:start_kernel() --> rest_init() --> kernel_thread() --> kernel_init() --> init_post() current->signal->flags |= SIGNAL_UNKILLABLE

Support additional argument in reboot reboot syscall can be performed with an additional argument. In some systems this functionality can be useful to modify the mode of the next boot performed by the bootloader.
