There is a bug that T_ZOMBIE objects are not collected.
Because there is a pass to miss finalizer postponed job
with multi-threading. This patch solve this issue.
* vm_trace.c (rb_postponed_job_register_one): set
RUBY_VM_SET_POSTPONED_JOB_INTERRUPT(th) if another same job
is registered.
There is a possibility to remain a postponed job without
interrupt flag.
* vm_trace.c (rb_postponed_job_register_one): check interrupt
carefully.
* vm_trace.c (rb_postponed_job_register_one): use additional space
to avoid buffer full.
* gc.c (gc_finalize_deferred_register): check failure.
* thread.c (rb_threadptr_execute_interrupts): check
`postponed_job_interrupt' immediately. There is a possibility
to miss this flag.

once at last.
* vm_trace.c (rb_postponed_job_flush): defer calling postponed jobs

Pre-allocate MAX_POSTPONED_JOB (1024) sized buffer
and use it.
If rb_postponed_job_register() cause overflow, simply it
fails and returns 0.
And maybe rb_postponed_job_register() is signal safe.

* RUBY_INTERNAL_EVENT_NEWOBJ: object created.
* RUBY_INTERNAL_EVENT_FREE: object freeed.
* RUBY_INTERNAL_EVENT_GC_START: GC started.
And rename `RUBY_EVENT_SWITCH' to `RUBY_INTERNAL_EVENT_SWITCH'.
Internal events can not invoke any Ruby program because the tracing
timing may be critical (under huge restriction).
These events can be hooked only by C-extensions.
We recommend to use rb_potponed_job_register() API to call Ruby
program safely.
This change is mostly written by Aman Gupta (tmm1).

[Feature #8107]
* include/ruby/debug.h, vm_trace.c: added two new APIs.
* rb_tracearg_event_flag() returns rb_event_flag_t of this event.
* rb_tracearg_object() returns created/freeed object.

ext/-test-/tracepoint/tracepoint.c,

Postponed jobs are registered with this API. Registered jobs
are invoked at `ruby-running-safe-point' as soon as possible.
This timing is completely same as finalizer timing.
There are two APIs:
* rb_postponed_job_register(flags, func, data): register a
postponed job with data. flags are reserved.
* rb_postponed_job_register_one(flags, func, data): same as
`rb_postponed_job_register', but only one `func' job is
registered (skip if `func' is already registered).
This change is mostly written by Aman Gupta (tmm1).

[Feature #8107]
* gc.c: use postponed job API for finalizer.
* common.mk: add dependency from vm_trace.c to debug.h.
* ext/-test-/postponed_job/extconf.rb, postponed_job.c,

of IFUNC frame.
When `rb_binding_new_with_cfp()' is called, VM finds out the first
normal (has iseq) frame and create a binding object of this frame
and create Env objects. `ep's of related frames are updated
(`ep's point Env object managed spaces).
However, `ep' of skipped IFUNC frame was not updated and
old invalid `ep' was remained. It causes serious problems.
To solve this issue, permit IFUNC to create binding.
(Maybe there is no problem on it)
[ruby-dev:46908] [ruby-trunk - Bug #7774]
* test/ruby/test_settracefunc.rb: add a test.
* vm.c (rb_vm_get_binding_creatable_next_cfp), vm_core.h: added.

The order of making binding should be stack (frame) top to bottom.

And also fix issue of collecting klass. Collecting klass is same
as TracePoint#defined_class.
(previous version, it returns T_ICLASS (internal objects).
* test/-ext-/debug/test_debug.rb: add a test.
* ext/-test-/debug/extconf.rb, init.c, inspector.c: ditto.
* vm_backtrace.c: remove magic number and add enum CALLER_BINDING_*.
* vm_backtrace.c, include/ruby/debug.h: add new C api (experimental)
rb_debug_inspector_frame_self_get().
* vm.c, vm_core.h, vm_trace.c: move decl. of
rb_vm_control_frame_id_and_class() and constify first parameter.

This flag is not contained by RUBY_EVENT_TRACEPOINT_ALL.
This event is experimental one. It is possible to remove/rename
flag name after 2.0.1.

JUMP_TAG() if frame is `finish' frame.
Without this patch, there is an inconsistency between control
frame stack and tags stack.

This change fix bug of Ruby 1.9.
[ruby-core:51128] [ruby-trunk - Bug #7624]
* vm_core.h (EXEC_EVENT_HOOK_AND_POP_FRAME): add to use
`rb_threadptr_exec_event_hooks_and_pop_frame()'.
* vm.c (vm_exec): use EXEC_EVENT_HOOK_AND_POP_FRAME() while
exception handling. While exception hadnling, if an exception
is raised in hooks, need to pop current frame and raise this
raised exception by hook.
* test/ruby/test_settracefunc.rb: add a test.

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.

counter. And if tracing is already true, vm_trace_running ops is
skipped to control overflow.

singleton class. `set_trace_func' passed attached class (which is
attached/modified by singleton class) by 6th block parameter if it
is singleton class. Previous behavior follows this spec.
However, this method named `defined_class' should return singleton
class directly because singleton methods are defined in singleton
class. There are no compatible issue because TracePoint is introduced
after 2.0.
But compatiblity with `set_trace_func' is brokne. This means that
you can not replace all `set_trace_func' code with TracePoint
without consideration of this behavior.
