* vm_trace.c, vm_core.h: simplify tracing mechanism.
(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.
