Generators that suspended a fiber should not be dtor because they will be
executed during the fiber dtor.
Fiber dtor throws an exception in the fiber's context in order to unwind and
execute finally blocks, which will also properly dtor the generator.
Fixes GH-9916
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.

- for packed arrays we store just an array of zvals without keys.
- the elements of packed array are accessible throuf as ht->arPacked[i]
instead of ht->arData[i]
- in addition to general ZEND_HASH_FOREACH_* macros, we introduced similar
familied for packed (ZEND_HASH_PACKED_FORECH_*) and real hashes
(ZEND_HASH_MAP_FOREACH_*)
- introduced an additional family of macros to access elements of array
(packed or real hashes) ZEND_ARRAY_ELEMET_SIZE, ZEND_ARRAY_ELEMET_EX,
ZEND_ARRAY_ELEMET, ZEND_ARRAY_NEXT_ELEMENT, ZEND_ARRAY_PREV_ELEMENT
- zend_hash_minmax() prototype was changed to compare only values
Because of smaller data set, this patch may show performance improvement
on some apps and benchmarks that use packed arrays. (~1% on PHP-Parser)
TODO:
- sapi/phpdbg needs special support for packed arrays (WATCH_ON_BUCKET).
- zend_hash_sort_ex() may require converting packed arrays to hash.
This prevents serialization and unserialization of a class and its
children in a way that does not depend on the zend_class_serialize_deny
and zend_class_unserialize_deny handlers that will be going away
in PHP 9 together with the Serializable interface.
In stubs, `@not-serializable` can be used to set this flag.
This patch only uses the new flag for a handful of Zend classes,
converting the remainder is left for later.
Closes GH-7249.
Fixes bug #81111.
In the added test case, the Closure ends up being freed before
the generator during GC.
This patch closes the generator (and thus releases the held
closure / execute_data) already during dtor_obj, which will avoid
ordering issues in free_obj. dtor_obj is not always called, but
if it isn't, then we also won't run GC and will free_obj in
reverse construction order.
Fixes oss-fuzz #33947.

We're starting to see a mix between uses of zend_bool and bool.
Replace all usages with the standard bool type everywhere.
Of course, zend_bool is retained as an alias.
