Fix out of bound writes to SafeArray data

Converting PHP arrays to Variants originally supported almost arbitrary
numeric arrays, possibly filling gaps with NULL values. This is broken
as of PHP 7.0.0[1] so that the SafeArray only has as many elements as
the PHP array. Thus, unless the array is a list, some elements may be
written outside of the SafeArray data.

To avoid breaking userland code after that long time, we do not restore
the original behavior, but instead only suppress the erroneous writes.

To avoid the need to split the regression test for 32bit and 64bit
Windows, we suppress the "max number 4294967295 of elements in safe
array exceeded" warning, which only occurs for 64bit versions.

As a user I expect `curl_multi_add_handle` to not have any effect if it returns

Fix GH-16292: Segmentation fault in ext/xmlreader/php_xmlreader.c:1282

3 issues:
1) RETURN_NULL() was used via the macro NODE_GET_OBJ(), but the function
returns false on failure and cannot return null according to its
stub.
2) The struct layout of the different implementors of libxml only
guarantees overlap between the node pointer and the document
reference, so accessing the std zend_object may not work.
3) DOC_GET_OBJ() wasn't using ZSTR_VAL().

Closes GH-16307.

Fix GH-16261: Reference invariant broken in mb_convert_variables()

The behaviour is weird in the sense that the reference must get
unwrapped. What ended up happening is that when destroying the old
reference the sources list was not cleaned properly. We add handling for
that. Normally we would use use ZEND_TRY_ASSIGN_STRINGL but that doesn't
work here as it would keep the reference and change values through
references (see bug #26639).

Fixed GH-16233: Observer segfault when calling user function in internal function via trampoline

Fixed GH-16233: Observer segfault when calling user function in internal function via trampoline

In the test, I have an internal `__call` function for `_ZendTestMagicCallForward` that calls the global function with name `$name` via `call_user_function`.
Note that observer writes the pointer to the previously observed frame in the last temporary of the new call frame (`*prev_observed_frame`).

The following happens:
First, we call `$test->callee`, this will be handled via a trampoline with T=2 for the two arguments. The call frame is allocated at this point. This call frame is not observed because it has `ZEND_ACC_CALL_VIA_TRAMPOLINE` set. Next we use `ZEND_CALL_TRAMPOLINE` to call the trampoline, this reuses the stack frame allocated earlier with T=2, but this time it is observed. The pointer to the previous frame is written outside of the call frame because `T` is too small (should be 3). We are now in the internal function `_ZendTestMagicCallForward::__call` where we call the global function `callee`. This will push a new call frame which will overlap `*prev_observed_frame`. This value gets overwritten by `zend_init_func_execute_data` when `EX(opline)` is set because `*prev_observed_frame` overlaps with `EX(opline)`. From now on, `*prev_observed_frame` is corrupted. When `zend_observer_fcall_end` is called this will result in reading wrong value `*prev_observed_frame` into `current_observed_frame`. This causes issues in `zend_observer_fcall_end_all` leading to the segfault we observe.

Despite function with `ZEND_ACC_CALL_VIA_TRAMPOLINE` not being observed, the reuse of call frames makes problems when `T` is not large enough.
To fix this, we make sure to add 1 to `T` if `ZEND_OBSERVER_ENABLED` is true.

Closes GH-16252.
