Modified Files:
	basesrc/lib/libc/gen: sysctl.3
	basesrc/sbin/sysctl: sysctl.8
	syssrc/sys/kern: kern_exec.c kern_fork.c kern_sysctl.c
	syssrc/sys/sys: proc.h sysctl.h

Log Message:
Added two sysctl-able flags: proc.curproc.stopfork and proc.curproc.stopexec
that can be used to block a process after fork(2) or exec(2) calls. The
new process is created in the SSTOP state and is never scheduled for running.

This feature is designed so that it is esay to attach the process using gdb
before it has done anything.

It works also with sproc, kthread_create, clone...
