Some old implementaions of arc4random_buf(3) were ARC4 based, or
unsafe when forked, or both. Resort to /dev/urandom for those
known problematic cases. Fix [Bug #15039]

Interrupt timing is tricky and it's possible the target
thread is still stopped from the previous loop iteration.

Otherwise, th->root_fiber can point to an invalid Fiber,
because Fibers do not live across fork. So consider
whatever Fiber is running the root fiber.

`acquired' was an old boolean variable, but nowadays it is a
rb_thread_t pointer; "gvl.owner" seems like a more appropriate
name. And document the contended path including waitq, timer,
and timer_err.

Oddly, all existing test cases passed multiple times
before this patch (even with --jit-wait), so this seems
like a difficult failure to prove.

Introduce a new rb_thread_sleep_interruptible that does not
execute interrupts before sleeping. Skipping the interrupt
check before sleep is required for out-of-GVL ruby_waitpid_all
to function properly when setting waitpid_state.ret
Now that ubf_select can be called by the gvl.timer thread
without recursive locking gvl.lock, we can safely use
rb_threadptr_interrupt to deal with waking up sleeping
processes,
git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@64576 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
This simplifies the locking logic somewhat.
While we're at it, designate_timer_thread is worthless in
ubf_select because gvl_acquire_common already guarantees there
is a gvl.timer if gvl->waitq is populated.
In the future (for auto-fiber), this will allow using
th->unblock.func for rb_waitpid callers (via rb_sigchld_handler).
