* vm_core.h, vm_trace.c: fix multi-threading bug for tracing.
Move `trace_arg' from rb_tp_t::trace_arg to rb_thread_t::trace_arg.
`trace_arg' may changed by multiple threads.
rb_thread_t::trace_arg can represent rb_thread_t::trace_running
(null or non-null) and rb_thread_t::trace_running is removed.
After that, `rb_tp_t' is not needed to check tracing or not
(A running thread knows tracing or not). This is why I remove
tp_attr_check_active() and make new function get_trace_arg().
And this modification disable to work the following code:
TracePoint.trace{|tp|
Thread.new{p tp.event} # access `tp' from other threads.
}
I believe nobody mix threads at trace procedure.
This is current limitation.
* cont.c (fiber_switch, rb_cont_call): use rb_thread_t::trace_arg
instead of rb_thread_t::trace_running.
* test/ruby/test_settracefunc.rb: add a multi-threading test.
