pythongh-149430: Fix edge-cases in `profiling.sampling` outputs (pythonGH-149431)

The line highlights on the heatmap are driven by the URL hash and the
`:target` selector. When clicking a caller/callee link for the line that
was already selected, the hash doesn't change, so the browser keeps the
existing target state and doesn't restart the animation. Due to this the
highlight only works the first time.

With this fix, line navigation goes through JavaScript. If the target
URL already points to the current location, the highlight is replayed by
clearing the animation, forcing style recalculation, and restoring it.

The `baseline_self` variable isn't initialized for structural elided
roots. This variable is accessed later unconditionally and leads to a
crash.

The child process ends up being invoked with `--diff_flamegraph` instead
of the correct argument.

pythongh-139871: Fix 3.15 bytearray.take_bytes example (pythonGH-149520)

Currently:
```python
buffer = bytearray(b'abc\ndef')
n = buffer.find(b'\n')
data = bytes(buffer[:n + 1])
del buffer[:n + 1]
assert data == b'abc'
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
    assert data == b'abc'
           ^^^^^^^^^^^^^^
AssertionError
```

Adding in the `\n` makes the two match:

```python
buffer = bytearray(b'abc\ndef')
n = buffer.find(b'\n')
data = bytes(buffer[:n + 1])
del buffer[:n + 1]
assert data == b'abc\n'
assert buffer == bytearray(b'def')

buffer = bytearray(b'abc\ndef')
n = buffer.find(b'\n')
data = buffer.take_bytes(n + 1)
assert data == b'abc\n'
assert buffer == bytearray(b'def')
```

The data filter rewrote linknames with normpath() but ran the
containment check against the un-normalised value, and computed a
symlink's directory before stripping trailing slashes.  Both let a
crafted archive create links pointing outside the destination.  Also
reject link members that resolve to the destination directory itself,
which could otherwise replace it with a symlink and redirect all
subsequent members.

…readed builds (pythongh-145233) (python#149690)

In free-threaded builds, concurrent calls to PyDict_AddWatcher, PyDict_ClearWatcher, PyDict_Watch, and PyDict_Unwatch can race on the shared callback array and the per-dict watcher tags. This change adds a mutex to serialize watcher registration and removal, atomic operations for tag updates, and atomic acquire/release synchronization for callback dispatch in _PyDict_SendEvent.

pythongh-87451: Apply CVE-2021-4189 PASV fix to ftplib.ftpcp() (pythonGH-149648)

ftpcp() called parse227() directly and passed the source server's
self-reported PASV IPv4 address to the target server's PORT command,
bypassing the CVE-2021-4189 fix that was applied only to FTP.makepasv().
A malicious source FTP server could use this to redirect the target
server's data connection to an arbitrary host:port (SSRF).

ftpcp() now uses the source server's actual peer address, honoring the
existing trust_server_pasv_ipv4_address opt-out, the same as makepasv().

pythongh-149707: Fix compiler warning in _ctypes_test on strchr() (python#149791)

Change my_strchr() return type to "const char*" (add "const").

Fix the compiler warning:

Modules/_ctypes/_ctypes_test.c:451:12: warning: return discards
'const' qualifier from pointer target type [-Wdiscarded-qualifiers]

When using C23, strchr(text, ch) return type is "const char*" if text
type is "const char*".

`faulthandler_traverse` visits Python objects owned by `_PyRuntime`, not
by the module instance. With multi-phase init allowing multiple module
instances, each instance's GC traversal decrements `gc_refs` on the same
runtime-owned objects, driving it negative when two instances are
collected simultaneously.
