	Restores default signal handlers under Linux/UNIX.
void	sigINT_handler (int signum)
	handles signals that lead to termination of the program such as SIGINT, SIGQUIT, SIGABRT, SIGSEGV, SIGTERM, SIGCHLD this function specifically works when the client aplication launched by pcm – terminates

	handles signals that lead to restart the application such as SIGHUP. for example to re-read environment variables controlling PCM execution
void	sigUSR_handler (int signum)
	handles signals that lead to update of configuration such as SIGUSR1 and SIGUSR2. for the future extensions
void	sigSTOP_handler (int signum)
