(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.

Thread#[]= are fiber-local and not thread-local.
reported by Julien A. [ruby-core:41606] [ruby-trunk - Bug #5750]

dfp (dynamic frame pointer) to ep (environment pointer).
This change make VM `normal' (similar to other interpreters).
Before this commit:
Each frame has two env pointers lfp and dfp. lfp points
local environment which is method/class/toplevel frame.
lfp[0] is block pointer.
dfp is block local frame. dfp[0] points previous (parent)
environment pointer.
lfp == dfp when frame is method/class/toplevel.
You can get lfp from dfp by traversing previous environment
pointers.
After this commit:
Each frame has only `ep' to point respective enviornoment.
If there is parent environment, then ep[0] points parent
envioenment (as dfp). If there are no more environment,
then ep[0] points block pointer (as lfp). We call such ep
as `LEP' (local EP). We add some macros to get LEP and to
detect LEP or not.
In short, we replace dfp and lfp with ep and LEP.
rb_block_t and rb_binding_t member `lfp' and `dfp' are removed
and member `ep' is added.
rename rb_thread_t's member `local_lfp' and `local_svar' to
`root_lep' and `root_svar'.
(VM_EP_PREV_EP(ep)): get previous environment pointer. This macro
assume that ep is not LEP.
(VM_EP_BLOCK_PTR(ep)): get block pointer. This macro assume
that ep is LEP.
(VM_EP_LEP_P(ep)): detect ep is LEP or not.
(VM_ENVVAL_BLOCK_PTR(ptr)): make block pointer.
(VM_ENVVAL_BLOCK_PTR_P(v)): detect v is block pointer.
(VM_ENVVAL_PREV_EP_PTR(ptr)): make prev environment pointer.
(VM_ENVVAL_PREV_EP_PTR_P(v)): detect v is prev env pointer.
* vm.c: apply above changes.
(VM_EP_LEP(ep)): get LEP.
(VM_CF_LEP(cfp)): get LEP of cfp->ep.
(VM_CF_PREV_EP(cfp)): utility function VM_EP_PREV_EP(cfp->ep).
(VM_CF_BLOCK_PTR(cfp)): utility function VM_EP_BLOCK_PTR(cfp->ep).
* vm.c, vm_eval.c, vm_insnhelper.c, vm_insnhelper.h, insns.def:
apply above changes.
* cont.c: ditto.
* eval.c, eval_intern.h: ditto.
* proc.c: ditto.

handle timer_interrupt only on the first loop for the case to avoid
the infinite loop like following case:
* there is 2 Ruby threads (3 pthreads)
(1) main thread is waiting at gvl_yield:112 (native_cond_wait)
(2) sub thread works
(3) sub thread waits at gvl_yield:133 (native_mutex_unlock)
(4) main thread works
(5) main thread goes to gvl_acquire_common
(6) main thread call rb_wakeup_timer_thread
(7) timer thread set timer interrupt to the main thread
(8) main thread works
(9) main thread waits at gvl_acquire_common:64 (native_cond_wait)
(10) sub tread works
(11) set sub thread as the current thread
(12) run Ruby thread
(13) ...100ms
(14) sub thread goes to rb_threadptr_execute_interrupts_common
(15) sub thread call rb_thread_schedule_limits
(16) sub thread call gvl_release_common
(17) sub threads waits at gvl_yield:121 (native_cond_wait)
(18) main threads works
(19) main thread back to gvl_yield
(20) set main thread as the current thread
(21) main thread call gvl_yield
(22) main thread waits at gvl_yield:112 (native_cond_wait)
As described above, the main thread can't escape from
rb_threadptr_execute_interrupts_common.
