`php_stream_write()` returns `-1` on failure now, which has to be
catered to by `SplFileObject::fputcsv()` which still is supposed to
return `false` on failure.

Since the constructor of DirectoryIterator and friends is supposed to
accepts paths (i.e. strings without NUL bytes), we must not accept
arbitrary strings.
* Change a number of "resource used as offset" notices to warnings,
which were previously missed.
* Throw the "resource used as offset" warning for isset() as well.
* Make array_key_exists() behavior with regard to different key
types consistent with isset() and normal array accesses. All key
types now use the usual coercions and array/object keys throw
TypeError.
Closes GH-4887.
This is a fix for symfony/symfony#32995.
The behavior is:
* Throwing exception when loading parent/interface is allowed
(and we will also throw one if the class is simply not found).
* If this happens, the bucket key for the class is reset, so
it's possibly to try registering the same class again.
* However, if the class has already been used due to a variance
obligation, the exception is upgraded to a fatal error, as we
cannot safely unregister the class stub anymore.
This allows us to drop the intermediate allocation for
spl_pqueue_elem.
This fixes GC for SplPriorityQueue, because we can now directly
return a well-formed GC child buffer.
This removes an incorrect optimization (I think this code used to be
necessary to properly handle references in the Serializable based
implementation, but now this code just avoids an array duplication
in a way that is not sound).
No notice is thrown for list() accesses, because we did not come
to an agreement regarding patterns like
while ([$key, $value] = yield $it->next()) { ... }
where silent null access may be desirable.
No effort is made to suppress multiple notices in access chains
likes $x[0][0][0], because the technical complexity this causes
does not seem worthwhile.
