On 32-bit platforms, expanding the fiber pool by a large amount may fail,
even if a smaller amount may succeed. We limit the maximum size of a single
allocation to maximise the number of fibers that can be allocated.
Additionally, we implement the book-keeping required to free allocations
when their usage falls to zero.

Replace previous stack cache with fiber pool cache. The fiber pool
allocates many stacks in a single memory region. Stack allocation
becomes O(log N) and fiber creation is amortized O(1). Around 10x
performance improvement was measured in micro-benchmarks.

When using native fibers, do not load ucontext, as it isn't needed.

During fork, it's possible that threads with root fibers are terminated,
but fiber state is not updated. `fiber_verify` will subsequently fail. We
forcefully enter the FIBER_TERMINATED state when terminating the root
fiber.
|
|
If `vm_stack` is left dangling in a forked process, the gc attempts to scan
it, but it is invalid and will cause a segfault. Therefore, we clear it
before forking.
In order to simplify this, `rb_ec_clear_vm_stack` was introduced.

This commit adds compaction support for:
* Fibers
* Continuations
* Autoload Constants
|
|
r59829 stopped clearing stack_start and enabled the code for
!FIBER_USE_NATIVE, but we need to do the same for register_stack_start
on ia64, otherwise we end up with NULL in cont_save_machine_stack.

This allows raising exceptions in another fiber, similarly to
Thread#raise.

* cont.c (cont_restore_thread): cause error if trace-status is changed.

* vm_trace.c (rb_tracepoint_enable_for_target): support targetting
TracePoint. [Feature #15289]
Tragetting TracePoint is only enabled on specified method, proc
and so on, example: `tp.enable(target: code)`.
`code` should be consisted of InstructionSeuqnece (iseq)
(RubyVM::InstructionSeuqnece.of(code) should not return nil)
If code is a tree of iseq, TracePoint is enabled on all of
iseqs in a tree.
Enabled tragetting TracePoints can not enabled again with
and without target.
* vm_core.h (rb_iseq_t): introduce `rb_iseq_t::local_hooks`
to store local hooks.
`rb_iseq_t::aux::trace_events` is renamed to
`global_trace_events` to contrast with `local_hooks`.
* vm_core.h (rb_hook_list_t): add `rb_hook_list_t::running`
to represent how many Threads/Fibers are used this list.
If this field is 0, nobody using this hooks and we can
delete it.
This is why we can remove code from cont.c.
* vm_core.h (rb_vm_t): because of above change, we can eliminate
`rb_vm_t::trace_running` field.
Also renamed from `rb_vm_t::event_hooks` to `global_hooks`.
* vm_core.h, vm.c (ruby_vm_event_enabled_global_flags): renamed
from `ruby_vm_event_enabled_flags.
* vm_core.h, vm.c (ruby_vm_event_local_num): added to count
enabled targetting TracePoints.
* vm_core.h, vm_trace.c (rb_exec_event_hooks): accepts
hook list.
* vm_core.h (rb_vm_global_hooks): added for convinience.
* method.h (rb_method_bmethod_t): added to maintain Proc
and `rb_hook_list_t` for bmethod (defined by define_method).
* prelude.rb (TracePoint#enable): extracet a keyword parameter
(because it is easy than writing in C).
It calls `TracePoint#__enable` internal method written in C.
* vm_insnhelper.c (vm_trace): check also iseq->local_hooks.
* vm.c (invoke_bmethod): check def->body.bmethod.hooks.
* vm.c (hook_before_rewind): check iseq->local_hooks
and def->body.bmethod.hooks before rewind by exception.

FIBER_USE_NATIVE is always defined as 0 or 1, use `#if` instead of
`#ifdef`.

* random.c: annotate rb_hash_start with NO_SANITIZE (seed.key.hash + h
overflows and that seems intentional)

The only usage of rb_fiber_reset_root_local_storage() is from
ruby_vm_destruct(), where the object space is already terminated.
This `th->self` is not alive. Why not just use `th` itself.
