We address the `::setSize(0)` case by setting `array->element = NULL`
and `array->size = 0` before we destroy the elements.

Closes GH-7503.
offsetSet did not account for the fact that the array may no longer exist after
the field is overwritten. This fixes that.
Add test of resizing both to the empty array and a smaller array - there should
be no valgrind warnings with a proper fix.
Alternate approach to #7486 (described in https://bugs.php.net/bug.php?id=81429)
`buf` may contain NUL bytes, so we must not use `strcspn()` but rather
a binary safe variant. However, we also must not detect a stray CR as
line ending, and since we only need to check line endings at the end
of the buffer, we can nicely optimize.

Closes GH-6836.
We need to always destroy current, not just when iter.data is not
set.
Take this opportunity to clean up the iterator destructor code a
bit, to remove redundant checks and incorrect comments.
When ArrayObject is round-tripped through serialize() and unserialize(),
it forgets any iterator class name which was set using ::setIteratorClass().
Fix that.
We actually implement `::__debugInfo()` and drop the `get_debug_info()`
handlers of all relevant SPL classes. This is cleaner and gives more
flexibility regarding overriding the functionality in descendant
classes.
Even though `SplStack::unserialize()` is not supposed to be called on
an already constructed instance, it is probably better if the method
clears the stack before actually unserializing.
`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.
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.

The test directory is often used for temporary files, let's use
the source directory, which should be more stable. If that doesn't
work we need to create a temporary directory.
This patch simplifies line endings tracked in the Git repository and
syncs them to all include the LF style instead of the CRLF files.
Newline characters:
- LF (\n) (*nix and Mac)
- CRLF (\r\n) (Windows)
- CR (\r) (old Mac, obsolete)
To see which line endings are in the index and in the working copy the
following command can be used:
`git ls-files --eol`
Git additionally provides `.gitattributes` file to specify if some files
need to have specific line endings on all platforms (either CRLF or LF).
Changed files shouldn't cause issues on modern Windows platforms because
also Git can do output conversion is core.autocrlf=true is set on
Windows and use CRLF newlines in all files in the working tree.
Unless CRLF files are tracked specifically, Git by default tracks all
files in the index using LF newlines.
