For typed properties that are of type "string", we don't need to do any
conversion as the zval will already be a string. Removing this
simplifies code and avoids unnecessary refcounting.

Fix GH-11625: DOMElement::replaceWith() doesn't replace node with DOMDocumentFragment but just deletes node or causes wrapping <></> depending on libxml2 version
Depending on the libxml2 version, the behaviour is either to not
render the fragment correctly, or to wrap it inside <></>. Fix it by
unpacking fragments manually. This has the side effect that we need to
move the unlinking check in the replacement function to earlier because
the empty child list is now possible in non-error cases.
Also fixes a mistake in the linked list management.
Closes GH-11627.
Change the way lifetime works in ext/libxml and ext/dom
Previously, a node could be freed even when holding a userland reference
to it. This resulted in exceptions when trying to access that node after
it has been implicitly or explicitly removed. After this patch, a node
will only be freed when the last userland reference disappears.
Fixes GH-9628.
Closes GH-11576.
For the past 20 years this threw a "not yet implemented" exception. But
the function was actually there (albeit not documented) and could be called...

* Remove obsolete workaround code
This code was for libxml2 <= 2.6.14. PHP requires at least libxml2
2.9.0.
* Use an inline check instead of calling into the library for an empty string check
When you construct a DOM tree containing subtrees which are constructed
top-down, this won't remove the redundant namespaces. That's because the
following conditions hold:
1) The namespace are reused from the doc->oldNs list.
2) Therefore during reconciliation no nsDef field is set, so no redundant
namespaces are removed by our reconciliation code.
Furthermore, it would only be fixed up automatically if the tree wasn't
added in bottom-up way, or if it had been constructed bottom-up from the
start.
Fix it by setting a flag to remove redundant namespaces in the libxml2
reconciliation call.
Since removing redundant namespaces may have a performance cost, we only do
this after performing a simple check.
Closes GH-11528.
* PHP-8.2:
Fix GH-11455: Segmentation fault with custom object date properties
Revert "Fix GH-11404: DOMDocument::savexml and friends ommit xmlns="" declaration for null namespace, creating incorrect xml representation of the DOM"
* PHP-8.1:
Revert "Fix GH-11404: DOMDocument::savexml and friends ommit xmlns="" declaration for null namespace, creating incorrect xml representation of the DOM"
This reverts commit 7eb3e9cd17.
Although the fix follows the spec, it causes issues because a lot of old
code assumes the incorrect behaviour PHP had since a long time.
We cannot do this yet, especially not in a stable release.
We revert this for the time being.
See GH-11428.
