Use Z_PARAM_OBJ macros when zval isn't needed

In some cases, like spl_object_id, the code is simpler but equally efficient
after optimizations.

In other cases, like get_mangled_object_vars(), the compiler can't infer that
the object in the zval won't change.

Allow removing non-existing key from WeakMap

In line with usual PHP semantics. This previously triggered an
assertion failure.

Fix use-after-free is WeakMap key and value are the same

Drop the object from the WeakMap as the last step, as this might
end up destroying the object.

Fix warnings of strict-prototypes

Add get_gc handle for object iterators

Optional handler with the same semantics as the object handler.

Introduce InternalIterator

Userland classes that implement Traversable must do so either
through Iterator or IteratorAggregate. The same requirement does
not exist for internal classes: They can implement the internal
get_iterator mechanism, without exposing either the Iterator or
IteratorAggregate APIs. This makes them usable in get_iterator(),
but incompatible with any Iterator based APIs.

A lot of internal classes do this, because exposing the userland
APIs is simply a lot of work. This patch alleviates this issue by
providing a generic InternalIterator class, which acts as an
adapater between get_iterator and Iterator, and can be easily
used by many internal classes. At the same time, we extend the
requirement that Traversable implies Iterator or IteratorAggregate
to internal classes as well.

Closes GH-5216.

Add flag to forbid dynamic property creation on internal classes

While performing resource -> object migrations, we're adding
defensive classes that are final, non-serializable and non-clonable
(unless they are, of course). This path adds a ZEND_ACC_NO_DYNAMIC_PROPERTIES
flag, that also forbids the creation of dynamic properties on these objects.
This is a subset of #3931 and targeted at internal usage only
(though may be extended to userland at some point in the future).

It's already possible to achieve this (what the removed
WeakRef/WeakMap code does), but there's some caveats: First, this
simple approach is only possible if the class has no declared
properties, otherwise it's necessary to special-case those
properties. Second, it's easy to make it overly strict, e.g. by
forbidding isset($obj->prop) as well. And finally, it requires a
lot of boilerplate code for each class.

Closes GH-5572.
