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 timing is completely same as finalizer timing.
There are two APIs:

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

This change is a part of RGENGC branch [ruby-trunk - Feature #8339].
* object.c: add new function rb_obj_reveal().
This function reveal interal (hidden) object by rb_obj_hide().
Note that do not change class before and after hiding.
Only permitted example is:
klass = RBASIC_CLASS(obj);
rb_obj_hide(obj);
....
rb_obj_reveal(obj, klass);
TODO: API design. rb_obj_reveal() should be replaced with others.
TODO: modify constified variables using cast may be harmful for
compiler's analysis and optimizaton.
Any idea to prohibt inserting RBasic::klass directly?
If rename RBasic::klass and force to use RBASIC_CLASS(obj),
then all codes such as `RBASIC(obj)->klass' will be
compilation error. Is it acceptable? (We have similar
experience at Ruby 1.9,
for example "RARRAY(ary)->ptr" to "RARRAY_PTR(ary)".
* internal.h: add some macros.
* RBASIC_CLEAR_CLASS(obj) clear RBasic::klass to make it internal
object.
* RBASIC_SET_CLASS(obj, cls) set RBasic::klass.
* RBASIC_SET_CLASS_RAW(obj, cls) same as RBASIC_SET_CLASS

* include/ruby/ruby.h (alloca), eval_intern.h (alloca), gc.c

ultimate ifdef's to ruby/ruby.h. Gcc hides its builtin alloca()
when compiling with -ansi, and linking thus fails on platforms
that lack their own alloca() implementation in libc, which
include OpenBSD and some ports of NetBSD. We use alloca()
everywhere including from within third party C extentions, so
alloca() must be made globally available. [Bug #7307]

internal object support.
If given object `obj' has references to internal objects
(such as T_NODE objects), then this method returns instances of
`ObjectSpace::InternalObjectWrapper' instead of that internal objects.
This instance contains a refereance to an internal object and you can
check the type of internal object using
`ObjectSpace::InternalObjectWrapper#type' method.
Rdoc of `InternalObjectWrapper' is not prepared yet.
* gc.c (rb_objspace_reachable_objects_from), gc.h: change
an interface of 'rb_objspace_reachable_objects_from()'
* gc.c, gc.h: add two APIs
- rb_objspace_markable_object_p(obj): check markable or not.
- rb_objspace_internal_object_p(obj): check internal or not.

This method returns an array of objects referenced by given object.
If given object is special objects such as true/false/nil/Fixnum etc
then it returns nil. See rdoc for details.
[ruby-core:39772]
* test/objspace/test_objspace.rb: add a test for this method.
* gc.c: add rb_objspace_reachable_objects_from().
To make this function, add several member `mark_func_data'
to rb_objspace_t. If mark_func_data is not null, then
gc_mark() calls mark_func_data::mark_func.
* gc.h: export rb_objspace_reachable_objects_from().

fail-safe system, but these systems not good at partial points,

64bit CPU environment (sizeof(double) == sizeof(VALUE)).
