Fix GH-15837: Segmentation fault in ext/simplexml/simplexml.c

We should check if the iterator data is still valid, because if it
isn't, then the type info is UNDEF, but the pointer value may be
dangling.

Closes GH-15841.

Because the signature is checked at compile time, we know that the only
possible return value (if there is no exception) is IS_LONG. So we can

Preferably include from build dir (#13516)

* Include from build dir first

This fixes out of tree builds by ensuring that configure artifacts are included
from the build dir.

Before, out of tree builds would preferably include files from the src dir, as
the include path was defined as follows (ignoring includes from ext/ and sapi/) :

-I$(top_builddir)/main
-I$(top_srcdir)
-I$(top_builddir)/TSRM
-I$(top_builddir)/Zend
-I$(top_srcdir)/main
-I$(top_srcdir)/Zend
-I$(top_srcdir)/TSRM
-I$(top_builddir)/

As a result, an out of tree build would include configure artifacts such as
`main/php_config.h` from the src dir.

After this change, the include path is defined as follows:

-I$(top_builddir)/main
-I$(top_builddir)
-I$(top_srcdir)/main
-I$(top_srcdir)
-I$(top_builddir)/TSRM
-I$(top_builddir)/Zend
-I$(top_srcdir)/Zend
-I$(top_srcdir)/TSRM

* Fix extension include path for out of tree builds

* Include config.h with the brackets form

`#include "config.h"` searches in the directory containing the including-file
before any other include path. This can include the wrong config.h when building
out of tree and a config.h exists in the source tree.

Using `#include <config.h>` uses exclusively the include path, and gives
priority to the build dir.

Fix argument type of simplexml_import_dom (#13170)

It needs to be "object".
This is because first- and third-party extension can register custom
node types using `php_libxml_register_export`. So we don't know upfront
what types can be expected.

This also changes the error to a TypeError everywhere.

Fix GH-12929: SimpleXMLElement with stream_wrapper_register can segfault

Move SimpleXML invalidation code after node checks

This is safe, i.e. the tree hasn't been modified yet, because either we
didn't call a libxml modification function yet, or xmlNewChild is called
with a NULL pointer, which makes it bail out and return NULL.

Apply SimpleXML iterator fixes only on master

Many methods in SimpleXML reset the iterator when called. This has the
consequence that mixing these operations with loops can cause infinite
loops, or the loss of iteration data.
Some people may however rely on the resetting behaviour. To prevent
unintended breaks in stable branches, let's only apply the fix to master.

This reverts GH-12193, GH-12229, GG-12247 for stable branches while
keeping them on master, adding a note in UPGRADING as well.
