Introduce new ptrace(2) operation PT_STOP
It works like:
- kill(SIGSTOP) for unstopped tracee
- ptrace(PT_CONTINUE,SIGSTOP) for stopped tracee
The child will be stopped and always possible to be waited (with wait(2)
like calls).
For stopped traccee kill(SIGSTOP) has no effect. PT_CONTINUE+SIGSTOP cannot
be used on an unstopped process (EBUSY).
This operation is modeled after PT_KILL that is similar for the SIGKILL
call. While there, allow PT_KILL on unstopped traced child.
This operation is useful in an abnormal exit of a debugger from a signal
handler, usually followed by waitpid(2) and ptrace(PT_DETACH).
