There's no direct call for doing to, i.e. a thread_start & thread_cont
call. But there's a way of achieving the same. Use ex_regs with the
L4_THREAD_EX_REGS_RAISE_EXCEPTION flag which will force the thread in
an exception state. When the thread should go on the exception handler
can just reply to the exception and the thread will go on where it was
stopped. You may also modify the exception handler while doing this.
