Apparently, this has been forgotten when PHP 8.0.17RC1 and 8.0.18RC1
had been tagged.
We also fix the version of the fix for GH-8253, which didn't make it
into PHP 8.0.18RC1.

This is achieved by tracking the observers on the run_time_cache (with a fixed amount of slots, 2 for each observer).
That way round, if the run_time_cache is freed all associated observer data is as well.
This approach has been chosen, as to avoid any ABI or API breakage.
Future versions may for example choose to provide a hookable API for run_time_cache freeing or similar.
This may happen, when the execute_data was allocated on the stack. We
ensure that the runtime cache pointer is not NULL before dereferencing
it.
This is a partial fix for bug 81430.
Closes GH-7665.
On NetBSD, ifconf.ifc_buf member, unlike most of platforms, is a void
pointer.
We also fix the cpuinfo declarations with empty parameter lists.
Closes GH-7819.
The amount of allocated system memory is kept in `real_size`, including
the allocated `cached_chunks`. Thus, we need to keep the proper count
at the end of the shutdown.
Closes GH-7745.
Trying to allocate a `zend_string` with a length only slighty smaller
than `SIZE_MAX` causes an integer overflow; we make sure that this
doesn't happen by catering to the maximal overhead of a `zend_string`.
Closes GH-7597.
Same as with userland classes, automatically add a string return
type to __toString() methods in internal classes, so the signature
is compatible with Stringable.
We also need to drop pi nodes for new_pred here, as the pi node
restriction for new_pred is not necessarily true for control
coming from old_pred as well.
Fixes oss-fuzz #40782.
Requiring all internal classes (including those from 3rd-party
extensions) to implement Stringable if they provide __toString()
is too error prone. Case in point, our _ZendTestClass test class
was not doing so, resulting in preloading test failures after
recent changes.
Instead we automatically implement Stringable, the same as we do
for userland classes. We still allow explicit implementations,
but ignore them (normally they would result in an error due to
duplicate interface implementation). Finally, we need to be
careful about not trying to implement Stringable on Stringable
itself.
In some cases this changes the interface order, in particular the
automatic Stringable implementation will now come first.
