Change from `void reboot(void)` to `int reboot(int mode)`. Move reboot definition to core, rename architecture implementations from reboot to reboot_arch. Declare reboot mode(s) in kernel.h, reboot_arch in kernel_internal.h Currently only one reboot mode is handled, its use is enforced. Rationale: A reboot function is already defined in <unistd.h> on BSD systems. (See: http://www.openbsd.org/cgi-bin/man.cgi?query=reboot&sektion=2) This patch not only allows native to build sensibly on these systems but also streamlines RIOTs compatability with existing software.
