This flag generates an arginfo file that discards all type and
default value information. As such, it is compatible with old
(and very old) PHP versions.
Intended for use by extensions to generate one arginfo file for
PHP 8 and one for older versions.
Currently compiler flags passed by extensions using the standard
``PHP_NEW_EXTENSION`` and ``PHP_ADD_SOURCES`` m4 macros are prepended
before the ones defined by ``Zend/Zend.m4``.
This was not really an issue before as ``Zend.m4`` only included
``-Wall`` but since the addition of ``-Wextra`` various issue about
disabling flags have been brought up.
A preliminary attempt was done in commit 5c1cf7669b
but this turns out to be more or less irrelevant.
The root issue is that ``PHP_NEW_EXTENSION`` and ``PHP_ADD_SOURCES`` call the
``PHP_ADD_SOURCES_X`` macro and pass their flags as the 3rd argument which prepends
the flags. There exists a 6th argument for this macro which appends them but from a
cursory look at https://heap.space/search?full=PHP_ADD_SOURCES_X&project=php-src
this is not used. Moreover, the comment describing this macro explicitly informs
that this macro should not be used directly.
As such we drop the 6th argument of ``PHP_ADD_SOURCES_X`` and move the `special-flags`
argument to be appended instead of prepended.

Given that this executes a random function with zero parameters,
actually executing the code doesn't make sense.
This should fix the imap + asan build.
With named arguments in php 8.0, it's important that php's modules
or PECL extensions using gen_stub.php don't generate functions
with duplicate names.
Warn if a parameter name is repeated,
even if the last occurrence is a variadic parameter

PHP-Parser 4.3.0 failed to recognize that the `match` keyword could be
used as a class constant name.
4.9.0 also adds support for keywords in namespaced names.
See https://github.com/nikic/PHP-Parser/releases
So forcing regeneration of spl_iterators.stub.php failed.
PECL extensions using gen_stub.php would also be affected
by the same issue.
```
ext/spl/spl_iterators.stub.php
public function __construct(Iterator $iterator, string $regex,
int $mode = self::MATCH, int $flags = 0, int $preg_flags = 0) {}
```
Testing: I successfully regenerated stubs by setting forceRegeneration to true
and running `touch **/*.stub.php; make`.
The stubs did not change, as expected.
Closes GH-6036
Since libxml version 2.9.0 external entity loading is disabled by default.
Bumping the version requirement means that XML processing in PHP is no
longer vulnerable to XXE processing attacks by default.
