Fix bug #78823: add zlib library to mysqlnd
The problem is newer binutils will no longer default to --copy-dt-needed-entries but use --no-copy-dt-needed-entries instead. So all libraries needed *must* be provided.
Workarounds (either one works)
1) Add "-Wl,--copy-dt-needed-entries" to LDFLAGS to bring back the old behavior of the linker
2) Add "-lz" to list of libraries to be added
In "ext/mysqlnd/mysqlnd_protocol_frame_codec.c" when the "zlib.h" header is included should also trigger adding '-lz' to the list of libraries.
We add the `is_seekable` member to `php_stdio_stream_data`, and prefer
that over `is_pipe`, since the latter is simply a misnomer. We keep
`is_pipe` for now for Windows only, though, because we need special
support for pipes there. We also fix the misaligned bitfield which
formerly took 33 bit.
Fix #78814: strip_tags allows / in tag name => whitelist bypass
When normalizing tags to check whether they are contained in the set
of allowable tags, we must not strip slashes, unless they come
immediately after the opening `<`, or immediately before the closing
`>`.
If we're constructing extended-length paths (i.e. paths prefixed with
`\\?\`), we have to replace all forward slashes with backward slashes,
because the former are not supported by Windows for extended-length
paths.
The more efficient and likely cleaner alternative solution would be to
cater to this in `php_win32_ioutil_normalize_path_w()` by always
replacing forward slashes, but that might break existing code. It
might be sensible to change that for `master`, though.
Partially revert "Adapt test cases for Oniguruma 6.9.4"
This partially reverts commit c55d09c2f547634b577aa5aeaa1438d772bc29d1,
because `MB_ONIGURUMA_VERSION` is only available as of PHP 7.4.0, so
that change made no sense for PHP-7.3; we keep it for PHP-7.4, though.
We also stick with the modification to bug78633.phpt.
Apparently, bug 78633 has now really been fixed; the former fix only
catered to the buffer overflow, but yielded a wrong result. Also,
the order of the named captures has been fixed.

Handle reallocated root buffer during GC destroy phase (v2)
We no longer protect GC during the destroy phase, so we need to
deal with buffer reallocation.
Note that the implementation of spl_SplObjectStorage_free_storage
will call the destructor of SplObjectStorage, and free the instance properties,
which I think is what caused the root buffer to be reallocated.
(`current` is a pointer for an index within the root buffer?)
Fix #78849: GD build broken with -D SIGNED_COMPARE_SLOW
Apparently, this has not been tested for a long time, and might be a
refactoring relict. Anyhow, we have to pass the context to
`GIFNextPixel` as well.

Make the UPGRADING note about ArrayObject more explicit.
We noticed the BC break when testing `curl_setopt()`, and hadn't interpreted
this note as affecting internal functions in general, so this adds a sub-bullet
to note that.
This overlaps a bit with the previous bullet, but since I don't know exactly
which operations were in mind at the time, I've elected to preserve them both.
Bits are cheap.

Do not let PHP-FPM children miss SIGTERM, SIGQUIT
Postpone signal delivery while spawning children.
Prevent the following case:
- Reload (reexec) is in progress.
- New master is forking to start enough children for pools
where `pm` is not `on-demand`.
- Another `SIGUSR2` is received by the master process.
- Master process switches to reloading state.
- Some child has not set its own signal handlers.
- `SIGQUIT` and `SIGTERM` sent by master process are caught
by signal handler set by master process and so they are ignored.
- A child is running, it has no reason to finish
Before pull request #4465 this scenario could cause deadlock,
however with 0ed6c37140 reload finishes after `SIGKILL`.
Use sigprocmask() around fork() to avoid race of delivery signal to children
and setting of own signal handlers.
Opcache stores `opline->handler`s in shared memory. These pointers are
invalid, if the main PHP DLL is loaded at another base address due to
ASLR. We therefore store the address of `execute_ex` in the mmap base
file, and check on startup whether it matches its current address. If
not, we fall back on the file cache if enabled, and bail out otherwise.
This still does not address cases where the opline handler is located
inside of another DLL (e.g. for some profilers, debuggers), but there
seems to be no general solution for now.
We use the portable {TMP} instead of the hard-coded /tmp, and skip
mysqli_debug_append.phpt on Windows, because unlinking the trace file
while the connection is still open won't work there.
