Commit 5cbe5a538c disabled chunking for all writes to streams. However,
user streams have a callback where code is executed on data that is
subject to the memory limit. Therefore, when using large writes or
stream_copy_to_stream/copy the memory limit can easily be hit with large
enough data.
To solve this, we reintroduce chunking for userspace streams.
Users have control over the chunk size, which is neat because
they can improve the performance by setting the chunk size if
that turns out to be a bottleneck.
In an ideal world, we add an option so we can "ask" the stream whether
it "prefers" chunked writes, similar to how we have
php_stream_mmap_supported & friends. However, that cannot be done on
stable branches.
Closes GH-13136.
php_strip_url_passwd modifies url in-place. We cannot assume from
php_message_handler_for_zend that data is a temporary, modifiable string.

Fix for #76857 introduced slight perf regression so this is an attempt
to fix it. The idea is to re-use stream path check from ZendAccelerator
that should be quicker than strstr.

Prior to the 8.1 rewrite, inet_aton was used for ipv4 addresses
therefore addresses like `0` passed.
For the bindto's case where both ip and port are set as such, we discard
the address binding.

This changes memory stream to allow seeking past end which makes it the
same as seeking on files. It means the position is allowed to be higher
than the string length. The size only increases if data is appended to
the past position. The space between the previous string and position
is filled with zero bytes.

* Zend: Make zend_strnlen available for use outside zend_compile
* exif: remove local php_strnlen, use zend_strnlen instead
* main: remove local strnlen, use zend_strnlen instead
* phar: remove local strnlen, use zend_strnlen
Mostly, extensions will use `PHP_VERSION` and `PHP_VERSION_ID`
respectfully but sometimes they want to grab the version at run-time
rather than at compile-time. For example, extensions which distribute
pre-built binaries may want this.
