Synchronize changes in runlevel with configuration reloads
State transition algorithm used this far could cause spurious component wakeups in some cases. Consider the following scenario: being in runlevel N, the configuration is changed so that a component X is added at runlevel N. Then a change to runlevel N+1 is initiated. What happens then is that X is woken up (still being in runlevel N) and terminated shortly afterwards, upon entering runlevel N+1. To avoid this, configuration must be reloaded after runlevel changes. * src/ctl.c (res_runlevel): Don't initiate ACTION_RELOAD after setting the runlevel. * src/pies.c (main): Begin main event loop with call to pies_pause. * src/pies.h (pies_set_hook): New proto. (inittrans): Remove proto. * src/socket.c (pies_set_hook): New function. (pies_pause): Call pies_pause_hook if defined. * src/sysvinit.c (inittrans): Change to static. If transition was initiated by user (e.g. by invoking telinit), schedule ACTION_RELOAD. (sysvinit_begin): Set inittrans as pies_hook
