[ruby/openssl] ossl.c: implement OpenSSL::OpenSSLError#detailed_message

An OpenSSL function sometimes puts more than one error entry into the
thread-local OpenSSL error queue. Currently, we use the highest-level
entry for generating the exception message and discard the rest....

Enumerator.produce accepts an optional size keyword argument

When not specified, the size is unknown (nil). Previously, the size was always Float::INFINITY and not specifiable.

YJIT: Fix panic from overly loose filtering in identity method inlining

Credits to @rwstauner (Randy Stauner) for noticing this issue in GH-15533.

Revert "ZJIT: Exclude failing ruby-bench benchmarks (#15479)"

This reverts commit 1eb10ca3cb6cff98bb8c0946ed905921586c7d52.

This should have been fixed by https://github.com/ruby/ruby/pull/15536.

ZJIT: Nil-fill locals in direct send (#15536)

Avoid garbage reads from locals in eval.
Before the fix the test fails with

<"[\"x\", \"x\", \"x\", \"x\"]"> expected but was
<"[\"x\", \"x\", \"x\", \"x286326928\"]">.

ZJIT: Don't inline non-parameter locals

YJIT: Add missing local variable type update for fallback setlocal blocks

Previously, the chain_depth>0 version of setlocal blocks did not
update the type of the local variable in the context. This can leave
the context with stale type information and trigger or lead to miscompilation....

ZJIT: Allow ccalls above 7 arguments (#15312)

ZJIT: Add stack support for CCalls

Cache filesystem_encindex

Store Encoding#name as an attribute

When debugging the fstring table, I found "UTF-8" to be the most common
interned strings in many benchmarks.

We have a fixed, limited number of these strings, so we might as well permanently
cache their fstrings.

Previously, the chain_depth>0 version of setlocal blocks did not
update the type of the local variable in the context. This can leave
the context with stale type information and trigger panics like in...

Fewer calls to GET_EC() and GET_THREAD() (#15506)

The changes are to io.c and thread.c.
I changed the API of 2 exported thread functions from internal/thread.h that
didn't look like they had any use in C extensions:

• rb_thread_wait_for_single_fd...

Prevent ifunc procs from being made shareable

[Bug #21775]

move th->event_serial to rb_thread_sched_item (#15500)

Array#rfind

Implement Array#rfind, which is the same as find except from the
other side of the Array. Also implemented Array#find (as opposed to
the generic one on Enumerable because it is significantly faster
and to keep the implementations together.

[Feature #21678]

ZJIT: Only optimize [] and []= for exact Hash, not Hash subclasses

ZJIT: Inline Hash#[]=

ZJIT: Add Shape type to HIR (#15528)

It's just a nicety (they fit fine as CUInt32) but this makes printing
look nicer in real execution and also in tests (helps with #15489).

Fix allocationless anonymous splat keyword argument check

Previously, if an argument splat and keywords are provided by

Fix binding.implicit_parameters_get/defined segfault when wrong name string is passed (#15530)

Update NEWS about Binding#implicit_parameters, etc.

[Bug #21049]

Add docs to Binding#numbered_parameters, etc.

Binding#implicit_parameters, etc. support the implicit "it" parameter

[Bug #21049]

Add Binding#implicit_parameters, etc.

This changeset introduces:

• Binding#implicit_parameters
• Binding#implicit_parameter_get
• Binding#implicit_parameter_defined?

[Bug #21049]

Simplify the code

thread_sched_to_waiting_common0 is no longer needed.

Avoid race condition in test_without_handle_interrupt_signal_works. (#15504)

thead_sync.c: directly pass the execution context to yield

Saves one more call to GET_EC()

Define Thread::ConditionVariable in thread_sync.rb

It's more consistent with Mutex, but also the #wait method
benefits from receiving the execution context instead of having
to call GET_EC.

Win32: Make rb_w32_osid return Windows NT always

Since support for Windows 9x was dropped over a decade ago.

dwMajorVersion alone has no meaning since Windows 7. Use API in
VersionHelper.h instead.

It has been fixed at Windows 8, and we already have dropped the
