Initialize child_watch_count to 1, so that we don't miss the very first

	* glib/gmain.c: Initialize child_watch_count to 1, so
	that we don't miss the very first child if it exits
	before we set up the child watch. In that case we had
	previously source->count == child_watch_count == 0,
	causing g_child_watch_check() to skip the waitpid()
	call.  (#154827, Gustavo Carneiro)

	* glib/gmain.c (g_child_watch_source_init_single)
	(g_child_watch_source_init_multi_threaded): Use sigaction()
	instead of signal().  (#136867, Jonas Jonsson, patch by
	Archana Shah)
