Konstantin Belousov 6ddcc23386 Add facility to stop all userspace processes. The supposed use of the ... feature is to quisce the system before suspend. Stop is implemented by reusing the thread_single(9) with the special mode SINGLE_ALLPROC. SINGLE_ALLPROC differs from the existing single-threading modes by allowing (requiring) caller to operate on other process. Interruptible sleeps for !TDF_SBDRY threads are suspended like SIGSTOP does it, instead of aborting the sleep, like SINGLE_NO_EXIT, to avoid spurious EINTRs on resume. Provide debugging sysctl debug.stop_all_proc, which causes total stop and suspends syncer, while waiting for variable reset for resume. It is used for debugging; should be removed after the real use of the interface is added.
