When declaring the same static property with a doc block in a class and in a trait,
the doc block of the property in the class is leaked. While at it, possibly fix doc
comment for internal classes.

These tests intermittently crash asan. It might be due to some function invoking
dl(), which is known to crash lsan. It might also be something else, the version
of asan shipped with ubuntu 22.04 is flaky.
Reorder when we assign the property value to NULL which is identical to

Just for the declared property case instead of dynamic.

Addref to relevant fields before allocating any memory. Also only set/remove the
ZEND_ACC_HEAP_RT_CACHE flag after allocating memory.
Fixes GH-12073
Closes GH-12074
With the fix in https://github.com/php/php-src/pull/12114, the behaviour
would change for non-dynamic properties. Align the behaviour for dynamic
properties to be the same.
Closes GH-12117.
Because the error handler is invoked after the property is updated,
the error handler has the opportunity to remove it before the property
is returned.
Switching the order around fixes this issue. The comments mention that
the current ordering prevents overwriting the EG(std_property_info)
field in the error handler. EG(std_property_info) no longer exists as it
was removed in 7471c217. Back then a global was used to store the
returned property info, but as this is no longer the case there is no
longer a need to protect against overwriting a global.
Closes GH-12062.
When executing a foreach ($ht as &$ref), foreach calls zend_hash_iterator_pos_ex() on every iteration. If the HashTable contained in the $ht variable is not the tracked HashTable, it will reset the position to the internal array pointer of the array currently in $ht.
This behaviour is generally fine, but undesirable for copy-on-write copies of the iterated HashTable. This may trivially occur when the iterated over HashTable is assigned to some variable, then the iterated over variable modified, leading to array separation, changing the HashTable pointer in the variable. Thus foreach happily restarting iteration.
This behaviour (despite existing since PHP 7.0) is considered a bug, if not only for the behaviour being unexpected to the user, also copy-on-write should not have trivially observable side-effects by mere assignment.
The bugfix consists of duplicating HashTableIterators whenever zend_array_dup() is called (the primitive used on array separation).
When a further access to the HashPosition through the HashTableIterators API happens and the HashTable does not match the tracked one, all the duplicates (which are tracked by single linked list) are searched for the wanted HashTable. If found, the HashTableIterator is replaced by the found copy and all other copies are removed.
This ensures that we always end up tracking the correct HashTable.
Fixes GH-11244.

This PR introduces a new way of recursion protection in JSON, var_dump
and friends. It fixes issue in master for __debugInfo and also improves
perf for jsonSerializable in some cases. More info can be found in
GH-10020.
