Switch the recursion check from the result of `get_properties_for`
(the returned hash table of properties) to just checking for
infinite recursion on the object.
- In order for a native datastructure to correctly implement
`*get_properties_for` for var_export's cycle detection,
it would need to return the exact same array every time prior to this PR.
Prior to this commit, the requirements for cycle detection
would prevent SplFixedArray or similar classes from returning a
temporary array that:
1. Wouldn't be affected by unexpected mutations from error handlers
2. Could be garbage collected instead.
* Emit deprecation warnings when adding dynamic properties to classes during unserialization - this will become an Error in php 9.0.
(Adding dynamic properties in other contexts was already a deprecation warning - the use case of unserialization was overlooked)
* Throw an error when attempting to add a dynamic property to a `readonly` class when unserializing
* Add new serialization methods `__serialize`/`__unserialize` for SplFixedArray to avoid creating deprecated dynamic
properties that would then be added to the backing fixed-size array
* Don't add named dynamic/declared properties (e.g. $obj->foo) of SplFixedArray to the backing array when unserializing
* Update tests to declare properties or to expect the deprecation warning
* Add news entry

This change primarily splits SAPI deactivation to module and destroy
parts. The reason is that currently some SAPIs might bail out
on deactivation. One of those SAPI is PHP-FPM that can bail out on
request end if for example the connection is closed by the client
(web sever). The problem is that in such case the resources are not
freed and some values reset. The most visible impact can have not
resetting the PG(headers_sent) which can cause erorrs in the next
request. One such issue is described in #77780 bug which this fixes
and is also cover by a test in this commit. It seems reasonable
to separate deactivation and destroying of the resource which means
that the bail out will not impact it.
We implement SQL_ATTR_CONNECTION_DEAD for ODBC and PDO_ODBC.
This is semantically appropriate and should be used whenever the
driver supports it. In the event that it fails or says the connection
isn't dead (which may be inaccurate in some cases), try the old
heuristic.
Closes GH-9353.
