(1) TracePoint.new(...){...} creates a new trace point
but does not make it enable.
(2) TracePoint.trace(...){...} creats a new trace point
and enable it (same as old behavior).
(3) TracePoint#enable make it enable (renamed from TracePoint#retrace).
If block given, when enable only in block.
(4) TracePoint#disable make it disable (renamed from TracePoint#untrace).
If block given, when disable only in block.
(5) TracePoint#enabled? returns this trace is enable or not.
* test/ruby/test_settracefunc.rb: addd tests.

(1) TracePoint#return_value which returns return
value on the :return and :c_return event.
(2) TracePoint#raised_exception which returns raised exception
value on the :raise event.
Eeach methods raise RuntimeError if it is called at unsupported
event.
Please review and give us feedback until next preview
release (Dec/2012) of Ruby 2.0.0.
* insns.def, vm.c, vm_eval.c, vm_insnhelper.c, eval.c, thread.c:
ditto.
* vm_trace.c, vm_core.h: move definition of rb_trace_arg_t from
vm_trace.c to vm_core.h.
Caller fills rb_trace_arg_t and pass the pointer of this variable.
* test/ruby/test_settracefunc.rb: fix tests to test this change.

vm_trace.c (rb_suppress_tracing): use TH_PUSH_TAG() instead of
PUSH_TAG().

`trace_running' to store vm global tracing status.
* vm_trace.c: fix SEGV bug. event_hook was free'd
even when the hook is still used in another thread.
[ruby-dev:46141] [Bug #7032]
git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@37280 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
* vm_trace.c (rb_threadptr_exec_event_hooks): fix uninitialized state
when no events is excuted.

* test/ruby/test_settracefunc.rb: add tests for above.
* proc.c (rb_binding_new_with_cfp): add an internal function.
* vm.c (rb_vm_control_frame_id_and_class): add an internal function.
* vm_trace.c: add rb_add_event_hook2() and rb_thread_add_event_hook2().
Give us the good name for them!

(1) add rb_hook_list_t data structure which includes
hooks, events (flag) and `need_clean' flag.
If the last flag is true, then clean the hooks list.
In other words, deleted hooks are contained by `hooks'.
Cleanup process should run before traversing the list.
(2) Change check mechanism
See EXEC_EVENT_HOOK() in vm_core.h.
(3) Add `raw' hooks APIs
Normal hooks are guarded from exception by rb_protect().
However, this protection is overhead for too simple
functions which never cause exceptions. `raw' hooks
are executed without protection and faster.
Now, we only provide registration APIs. All `raw'
hooks are kicked under protection (same as normal hooks).
* include/ruby/ruby.h: remove internal data definition and
macros.
* internal.h (ruby_suppress_tracing), vm_trace.c: rename
ruby_suppress_tracing() to rb_suppress_tracing()
and remove unused function parameter.
* parse.y: fix to use renamed rb_suppress_tracing().
* thread.c (thread_create_core): no need to set RUBY_VM_VM.
* vm.c (mark_event_hooks): move definition to vm_trace.c.
* vm.c (ruby_vm_event_flags): add a global variable.
This global variable represents all of Threads and VM's
event masks (T1#events | T2#events | ... | VM#events).
You can check the possibility kick trace func or not
with ruby_vm_event_flags.
ruby_vm_event_flags is maintained by vm_trace.c.
* cont.c (fiber_switch, rb_cont_call): restore tracing status.
[Feature #4347]
* test/ruby/test_continuation.rb: ditto.
