Backport e2d97314: Backport deprecation warning ignores to unbreak CI

In master I use ZEND_DIAGNOSTIC_IGNORED_START, but that doesn't exist on
8.2 or 8.3 (8.3 has a similar macro though).
So to unbreak CI I just made a variation of this directly in the
php_libxml.h header.

Implement request #30622: make $namespace parameter functional

This parameter never actually did anything and was forgotten about.
We solve this by detecting when we have a $namespace argument
(that won't conflict with the name argument) and creating a Clark
notation name out of it.

Closes GH-16123.

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.

refactor: change `zend_is_true` to return `bool` (#14301)

Previously this returned `int`. Many functions actually take advantage
of the fact this returns exactly 0 or 1. For instance,
`main/streams/xp_socket.c` does:

sockopts |= STREAM_SOCKOP_IPV6_V6ONLY_ENABLED * zend_is_true(tmpzval);

And `Zend/zend_compile.c` does:

child = &ast->child[2 - zend_is_true(zend_ast_get_zval(ast->child[0]))];

I changed a few places trivially from `int` to `bool`, but there are
still many places such as the object handlers which return `int` that
should eventually be `bool`.

Implement request #71571: XSLT processor should provide option to change maxDepth (#13731)

There are two depth limiting parameters for XSLT templates.
1) maxTemplateDepth
This corresponds to the recursion depth of a template. For very
complicated templates this can be hit.
2) maxTemplateVars
This is the total number of live variables. When using recursive
templates with lots of parameters you can hit this limit.

This patch introduces two new properties to XSLTProcessor that
corresponds to the above variables.

This reimplements the parameter handling. Instead of quoting the strings

libxslt API to pass data verbatim to the processor.

Sanitize libxml2 globals before parsing

Fixes GHSA-3qrf-m4j2-pcrr.

To parse a document with libxml2, you first need to create a parsing context.
The parsing context contains parsing options (e.g. XML_NOENT to substitute
entities) that the application (in this case PHP) can set.
Unfortunately, libxml2 also supports providing default set options.
For example, if you call xmlSubstituteEntitiesDefault(1) then the XML_NOENT
option will be added to the parsing options every time you create a parsing
context **even if the application never requested XML_NOENT**.

Third party extensions can override these globals, in particular the
substitute entity global. This causes entity substitution to be
unexpectedly active.

Fix it by setting the parsing options to a sane known value.
For API calls that depend on global state we introduce
PHP_LIBXML_SANITIZE_GLOBALS() and PHP_LIBXML_RESTORE_GLOBALS().
For other APIs that work directly with a context we introduce
php_libxml_sanitize_parse_ctxt_options().

Fix bug 69168: DomNode::getNodePath() returns invalid path

Upon freeing libxslt's context, every document which is not the *main*
document will be freed by libxslt. If a node of a document which is not
the main document gets returned to userland, we'd free the node twice:
- first by the cleanup of the xslt context
- and then by our own refcounting mechanism.
This was reported in bug 49634, and was fixed by always copying the
node (and later re-fixed in bug 70078).
The original fix is not entirely correct unfortunately because of the
following two main reasons:
- modifications to the node will only modify the copy, and not the original
- accesses to the parent, path, ... will not work

This patch fixes it properly by only copying the node if it origins from
a document other than the main document.
