Support templated content

The template element in HTML 5 is special in the sense that it does not
add its contents into the DOM tree, but instead keeps them in a separate
shadow DOM document fragment. Interacting with the DOM tree cannot touch
the elements in the document fragment.

Closes GH-14906.

Split off private data from the ns mapper

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.

Handle libxml2 OOM more consistently (#11927)

This is a continuation of commit c2a58ab07d, in which several OOM error
handling was converted to throwing an INVALID_STATE_ERR DOMException.
Some places were missed and they still returned false without an
exception, or threw a PHP_ERR DOMException.
Convert all of these to INVALID_STATE_ERR DOMExceptions. This also
reduces confusion of users going through documentation [1].

Unfortunately, not all node creations are checked for a NULL pointer.
Some places therefore will not do anything if an OOM occurs (well,
except crash).
On the one hand it's nice to handle these OOM cases.
On the other hand, this adds some complexity and it's very unlikely to
happen in the real world. But then again, "unlikely" situations have
caused trouble before. Ideally all cases should be checked.

Fix #79971: special character is breaking the path in xml function

The libxml based XML functions accepting a filename actually accept
URIs with possibly percent-encoded characters. Percent-encoded NUL
bytes lead to truncation, like non-encoded NUL bytes would. We catch
those, and let the functions fail with a respective warning.
