This merges all usages of emitting an offset TypeError into a new ZEND_API function
zend_illegal_container_offset(const zend_string* container, const zval *offset, int type);
Where the container should represent the type on which the access is attempted (e.g. string, array)
The offset zval that is used, where the error message will display its type
The type of access, which should be a BP_VAR_* constant, to get special message for isset/empty/unset
Object handlers being separate from class entries is a legacy inherited from PHP 5. Today it has little benefit to keep them separate: in fact, accessing object handlers usually requires not-so-safe hacks.
While it is possible to swap handlers in a custom installed create_object handler, this mostly is tedious, as well as it requires allocating the object handlers struct at runtime, possibly caching it etc..
This allows extensions, which intend to observe other classes to install their own class handlers.
The life cycle of internal classes may now be simply observed by swapping the class handlers in post_startup stage.
The life cycle of userland classes may be observed by iterating over the new classes in zend_compile_file and zend_compile_string and then swapping their handlers.
In general, this would also be a first step in directly tying the object handlers to classes. Especially given that I am not aware of any case where the object handlers would be different between various instances of a given class.

This reverts commit d0527427be.
This patch makes Swoole/Swow can not work anymore, because Coroutine will yield to another one during socket operation, EG(record_errors) assertion will always fail, and zend_begin_record_errors() was only used during compile time before.
Note: zend_emit_recorded_errors() and the typo fix are reserved.
This is not actually related to SSL handshake but stream socket creation
which does not clean errors if the error handler is set. This fix
prevents emitting errors until the stream is freed.
This doesn't have an effect really, but humans and IDEs can struggle to see through the macro soup when they first interact with PHP's source code.
Moreover, this reduces some of the macro expansion hell when they appear in compiler warnings.
Previously, code such as subclasses of SplFixedArray would check for method
overrides when instantiating the objects.
This optimization was mentioned as a followup to GH-6552
Currently, classes that can't be linked get moved back into the original script
and are not preloaded. As such classes may be referenced from functions that
did get preloaded, there is a preload autoload mechanism to load them at
runtime.
Since PHP 8.1, we can safely preload unlinked classes, which will then go
through usual lazy loading. This means that we no longer need the preload
autoload mechanism. However, we need to be careful not to modify any hash
table buckets in-place, and should create new buckets for lazy loaded classes.
