Reported by OpenAI AARDVARK.
php_zip_parse_option is only called when options are passed to the function.
Prior to this patch, php_zip_parse_option was responsible for zeroing the
opts variable. So in the case when php_zip_parse_option is not called,
opts remains uninitialized yet it is being used anyway.
By just always zeroing opts at declaration time, we avoid this issue
and we are unlikely to reintroduce this in the future.
Closes GH-18329.
* PHP-8.3:
Fix GH-18309: ipv6 filter integer overflow
Fix GH-18304: Changing the properties of a DateInterval through dynamic properties triggers a SegFault
The intermediate computation can cause a signed integer overflow, but
the input is correctly rejected later on by the check on variable `n`.
Solve this by using an unsigned number.
Closes GH-18312.
For dynamic fetches the cache_slot will be NULL, so we have to check for
that when resetting the cache. For zip and xmlreader this couldn't
easily be tested because of a lack of writable properties.
Closes GH-18307.
The JIT helper `zend_jit_assign_op_to_typed_ref` expects a `zval*` as an
argument, so we have to store to the stack if OP1_DATA(=op3) is in a
register.
Closes GH-18299.
This regressed in 62c7432f, prior to that commit the value was set to
false in case random number generation failed, but now even if an
exception is thrown it is set to true. This likely does not _really_
matter as the user will handle the exception, still the value in
$strong_result is observable.
Triggers the assertion as with SEEK_CUR the stream position is set to a
negative value so we force the failure without affecting its position
instead.

This resets all basic globals during ctor and just modifies the ones
with a special value. It also switches to using basic_globals_p which
what should be used in this context.
Closes GH-18156
