Fix GH-11078: PHP Fatal error triggers pointer being freed was not allocated and malloc: double free for ptr errors

Although the issue was demonstrated using Curl, the issue is purely in
the streams layer of PHP.

Full analysis is written in GH-11078 [1], but here is the brief version:
Here's what actually happens:
1) We're creating a FILE handle from a stream using the casting mechanism.
This will create a cookie-based FILE handle using funopen.
2) We're reading stream data using fread from the userspace stream. This will
temporarily set a buffer into a field _bf.base [2]. This buffer is now equal
to the upload buffer that Curl allocated and note that that buffer is owned
by Curl.
3) The fatal error occurs and we bail out from the fread function, notice how
the reset code is never executed and so the buffer will still point to
Curl's upload buffer instead of FILE's own buffer [3].
4) The resources are destroyed, this includes our opened stream and because the
FILE handle is cached, it gets destroyed as well.
In fact, the stream code calls through fclose on purpose in this case.
5) The fclose code frees the _bs.base buffer [4].
However, this is not the buffer that FILE owns but the one that Curl owns
because it isn't reset properly due to the bailout!
6) The objects are getting destroyed, and so the curl free logic is invoked.
When Curl tries to gracefully clean up, it tries to free the buffer.
But that buffer is actually already freed mistakingly by the C library!

This also explains why we can't reproduce it on Linux: this bizarre buffer
swapping only happens on macOS and BSD, not on Linux.

To solve this, we switch to an unbuffered mode for cookie-based FILEs.
This avoids any stateful problems related to buffers especially when the
bailout mechanism triggers. As streams have their own buffering
mechanism, I don't expect this to impact performance.

Fix number of elements after packed hash filling (#11022)

After a hash filling routine the number of elements are set to the fill
index. However, if the fill index is larger than the number of elements,
the number of elements are no longer correct. This is observable at
least via count() and var_dump(). E.g. the attached test case would
incorrectly show int(17) instead of int(11).

Solve this by only increasing the number of elements by the actual
number that got added. Instead of adding a variable that increments per
iteration, I wanted to save some cycles in the iteration and simply
compute the number of added elements at the end.

I discovered this behaviour while fixing GH-11016, where this filling
routine is easily exposed to userland via a specialised VM path [1].
Since this seems to be more a general problem with the macros, and may
be triggered outside of the VM handlers, I fixed it in the macros
instead of modifying the VM to fixup the number of elements.
