Koichi Sasada a87ae242bb Use noinline version of accessing current ec
On universal.arm64e-darwin22 with clang 15.0.0 (I didn't check
details yet) accessing `ruby_current_ec` directly causes
assertion violation `VM_ASSERT(ec == rb_current_ec_noinline())`
on `rb_current_execution_context()`, maybe because TLS accessing
issue.

Koichi Sasada be1bbd5b7d M:N thread scheduler for Ractors
This patch introduce M:N thread scheduler for Ractor system.

In general, M:N thread scheduler employs N native threads (OS threads)
to manage M user-level threads (Ruby threads in this case).
On the Ruby interpreter, 1 native thread is provided for 1 Ractor
and all Ruby threads are managed by the native thread.

From Ruby 1.9, the interpreter uses 1:1 thread scheduler which means
1 Ruby thread has 1 native thread. M:N scheduler change this strategy.

Because of compatibility issue (and stableness issue of the implementation)
main Ractor doesn't use M:N scheduler on default. On the other words,
threads on the main Ractor will be managed with 1:1 thread scheduler.

There are additional settings by environment variables:

`RUBY_MN_THREADS=1` enables M:N thread scheduler on the main ractor.
Note that non-main ractors use the M:N scheduler without this
configuration. With this configuration, single ractor applications
run threads on M:1 thread scheduler (green threads, user-level threads).

`RUBY_MAX_CPU=n` specifies maximum number of native threads for
M:N scheduler (default: 8).

This patch will be reverted soon if non-easy issues are found.

Koichi Sasada d9984f39d3 remove `NON_SCALAR_THREAD_ID` support
`NON_SCALAR_THREAD_ID` shows `pthread_t` is non-scalar (non-pointer)
and only s390x is known platform. However, the supporting code is
very complex and it is only used for deubg print information.

So this patch removes the support of `NON_SCALAR_THREAD_ID`
and make the code simple.

Koichi Sasada 03d21a4fb0 introduce struct `rb_native_thread`
`rb_thread_t` contained `native_thread_data_t` to represent
thread implementation dependent data. This patch separates
them and rename it `rb_native_thread` and point it from
`rb_thraed_t`.

Now, 1 Ruby thread (`rb_thread_t`) has 1 native thread (`rb_native_thread`).

* `gvl_destroy` -> `rb_thread_sched_destroy`
* `gvl_acquire` -> `thread_sched_to_running` # waiting -> ready -> running
* `gvl_release` -> `thread_sched_to_waiting` # running -> waiting
* `gvl_yield`   -> `thread_sched_yield`
* `GVL_UNLOCK_BEGIN` -> `THREAD_BLOCKING_BEGIN`
* `GVL_UNLOCK_END` -> `THREAD_BLOCKING_END`

* removed
  * `rb_ractor_gvl`
  * `rb_vm_gvl_destroy` (not used)

There are GVL functions such as `rb_thread_call_without_gvl()` yet
but I don't have good name to replace them. Maybe GVL stands for
"Greate Valuable Lock" or something like that.

Koichi Sasada 79df14c04b Introduce Ractor mechanism for parallel execution
This commit introduces Ractor mechanism to run Ruby program in
parallel. See doc/ractor.md for more details about Ractor.
See ticket [Feature #17100] to see the implementation details
and discussions.

[Feature #17100]

This commit does not complete the implementation. You can find
many bugs on using Ractor. Also the specification will be changed
so that this feature is experimental. You will see a warning when
you make the first Ractor with `Ractor.new`.

I hope this feature can help programmers from thread-safety issues.

卜部昌平 4ff3f20540 add #include guard hack
According to MSVC manual (*1), cl.exe can skip including a header file
when that:

- contains #pragma once, or
- starts with #ifndef, or
- starts with #if ! defined.

GCC has a similar trick (*2), but it acts more stricter (e. g. there
must be _no tokens_ outside of #ifndef...#endif).

Sun C lacked #pragma once for a looong time.  Oracle Developer Studio
12.5 finally implemented it, but we cannot assume such recent version.

This changeset modifies header files so that each of them include
strictly one #ifndef...#endif.  I believe this is the most portable way
to trigger compiler optimizations. [Bug #16770]

`acquired' was an old boolean variable, but nowadays it is a
rb_thread_t pointer;  "gvl.owner" seems like a more appropriate

normal d2afeb9445 thread_pthread.c: reset timeslice delay when uncontended
This matches the behavior of old timer thread more closely
and seems to fix [Bug #14999] when limited to a single CPU.
I cannot reproduce the error on a multi-core system unless
I use schedtool to force affinity to a single CPU:

schedtool -a 0x01 -e make test-spec \
	MSPECOPT='-R1000 spec/ruby/library/conditionvariable/wait_spec.rb'

While it may be good enough to pass the spec, I don't have
huge degree of confidence in the interrupt handling robustness
under extremely heavy load (these may be ancient bugs, though).

normal 708bfd2115 thread_pthread: remove timer-thread by restructuring GVL
To reduce resource use and reduce CI failure; remove
timer-thread.  Single-threaded Ruby processes (including forked
children) will never see extra thread overhead.  This prevents
glibc and jemalloc from going into multi-threaded mode and
initializing locks or causing fragmentation via arena explosion.

The GVL is implements its own wait-queue as a ccan/list to
permit controlling wakeup order.  Timeslice under contention is
handled by a designated timer thread (similar to choosing a
"patrol_thread" for current deadlock checking).

There is only one self-pipe, now, as wakeups for timeslice are
done independently using condition variables.  This reduces FD
pressure slightly.

Signal handling is handled directly by a Ruby Thread (instead
of timer-thread) by exposing signal self-pipe to callers of
rb_thread_fd_select, native_sleep, rb_wait_for_single_fd, etc...
Acquiring, using, and releasing the self-pipe is exposed via 4
new internal functions:

1) rb_sigwait_fd_get - exclusively acquire timer_thread_pipe.normal[0]

2) rb_sigwait_fd_sleep - sleep and wait for signal (and no other FDs)

3) rb_sigwait_fd_put - release acquired result from rb_sigwait_fd_get

4) rb_sigwait_fd_migrate - migrate signal handling to another thread
                           after calling rb_sigwait_fd_put.

rb_sigwait_fd_migrate is necessary for waitpid callers because
only one thread can wait on self-pipe at a time, otherwise a
deadlock will occur if threads fight over the self-pipe.

TRAP_INTERRUPT_MASK is now set for the main thread directly in
signal handler via rb_thread_wakeup_timer_thread.

Originally, I wanted to use POSIX timers
(timer_create/timer_settime) for this.  Unfortunately, this
proved unfeasible as Mutex#sleep resumes on spurious wakeups and
test/thread/test_cv.rb::test_condvar_timed_wait failed.  Using
pthread_sigmask to mask out SIGVTALRM fixed that test,  but
test/fiddle/test_function.rb::test_nogvl_poll proved there'd be
some unavoidable (and frequent) incompatibilities from that
approach.

Finally, this allows us to drop thread_destruct_lock and
interrupt current ec directly.

We don't need to rely on vm->thread_destruct_lock or a coherent
vm->running_thread on any platform.  Separate timer-thread for
time slice and signal handling is relegated to thread_win32.c,
now.

ko1 450463d5fb * thread.c, vm_core.h: make gvl_acquire/release/init/destruct
APIs to modularize GVL implementation.
* thread_pthread.c, thread_pthread.h: Two GVL implementations.
  (1) Simple locking GVL which is same as existing GVL.
  (2) Wake-up queued threads.  The wake-up order is simple FIFO.
  (We can make several queues to support exact priorities, however
  this causes some issues such as priority inversion and so on.)
  This impl. prevents spin-loop (*1) caused on SMP environemnts.
  *1: Only one Ruby thread acqures GVL again and again.
  Bug #2359 [ruby-core:26694]
* thread_win32.c, thread_win32.h: Using simple lock
  not by CRITICAL_SECTION but by Mutex.
  Bug #3890 [ruby-dev:42315]
* vm.c (ruby_vm_destruct): ditto.

naruse b323b86b6b * thread_pthread.c (native_thread_init_stack): use get_stack.
patched by KOSAKI Motohiro [ruby-dev:40309]

* thread_pthread.c (ruby_init_stack): use get_stack
  on platforms which have pthread_attr_get_np.
  (FreeBSD, DragonFlyBSD and NetBSD)
  This is because FreeBSD and DragonFly BSD must use
  pthread_attr_get_np to get stack size of main thread,
  but Mac OS X and Linux with LinuxThreads must use getrlimit.
