[ruby-core:55222] [Feature #8468]
* object.c (rb_obj_untrusted, rb_obj_untrust, rb_obj_trust):
Kernel#untrusted?, untrust, and trust are now deprecated.
Their behavior is same as tainted?, taint, and untaint,
respectively.
* include/ruby/ruby.h (OBJ_UNTRUSTED, OBJ_UNTRUST): OBJ_UNTRUSTED()
and OBJ_UNTRUST() are aliases of OBJ_TAINTED() and OBJ_TAINT(),
respectively.

RUBY_INTERNAL_EVENT_GC_END. This event invokes at the end of
after_sweep().
Time chart with lazy sweep is here:
(1) Kick RUBY_INTERNAL_EVENT_GC_START
(2) [gc_marks()]
(3) [lazy_sweep()]
(4) [... run Ruby program (mutator) with lazy_sweep() ...]
(5) [after_sweep()]
(6) Kick RUBY_INTERNAL_EVENT_GC_END
(7) [... run Ruby program (mutator), and go to (1) ...]

Read the following test to know HOWTO.
This feature is a sample of RUBY_INTERNAL_EVENT.
* test/objspace/test_objspace.rb: add a test.
* ext/objspace/object_tracing.c: ditto.
* gc.c (rb_gc_count): add. THis function returns GC count.
* internal.h: add decl. of rb_gc_count(). Same as `GC.count'.

* 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).
https://bugs.ruby-lang.org/issues/8107#note-12
[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/extconf.rb,
ext/-test-/tracepoint/tracepoint.c,
test/-ext-/tracepoint/test_tracepoint.rb: add a test.

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).
https://bugs.ruby-lang.org/issues/8107#note-15
[Feature #8107]
* gc.c: use postponed job API for finalizer.
* common.mk: add dependency from vm_trace.c to debug.h.

test/-ext-/postponed_job/test_postponed_job.rb: add a test.
* thread.c: implement postponed API.

(or garbage_collect_body()). `garbage_collect()' accept additional
two parameters `full_mark' and `immediate_sweep'.
If `full_mark' is TRUE, then force it full gc (major gc), otherwise,
it depends on status of object space. Now, it will be minor gc.
If `immediate_sweep' is TRUE, then disable lazy sweep.
To allocate free memory, `full_mark' and `immediate_sweep' should be
TRUE. Otherwise, they should be FALSE.
* gc.c (gc_prepare_free_objects): use `garbage_collect_body()'.
* gc.c (slot_sweep, before_gc_sweep, after_gc_sweep): add logging code.
