[3.14] gh-75572: Speed up test_xpickle (GH-144393) (GH-144403)
Run a long living subprocess which handles multiple requests instead of
running a new subprocess for each request.
(cherry picked from commit 29acc08c8dad664cd5713cb392e5beba65724c10)
Modifies handling of `.gz` files in Android app payloads, and ensures that
when the Android testbed streams logs, stream flushes aren't treated as
newlines. This improves the output of test suites that use "one dot per test"
progress indicators.

[3.14] gh-144295: Fix data race in dict method lookup and global load (gh-144312) (#144346)
In `_Py_dict_lookup_threadsafe_stackref`, call `ensure_shared_on_read()` to
prevent a race between the lookup and concurrent dict resizes, which may free
the PyDictKeysObject (i.e., it ensures that the resize uses QSBR).

The emulator images for API level 34 and 35 have significant issues with image size and
internet connectivity. Reverts the default API level used for testbed testing to 33.

gh-144194: Fix mmap failure check in perf_jit_trampoline.c (GH-143713)
mmap() returns MAP_FAILED ((void*)-1) on error, not NULL. The current
check never detects mmap failures, so jitdump initialization proceeds
even when the memory mapping fails.
(cherry picked from commit 8fe8a94a7c050bc16cac9ec300f89c0f389f9a44)
The code in test_makefile was attempting to ignore any
non-interesting files, but missed some corners:
1. There is never a *file* called `__pycache__`.
2. A directory containing only a `__pycache__` subdirectory should be
ignored.
3. A directory containing only hidden files should be ignored.

gh-141004: Mark up docs of old PyMem macros (GH-143783)
These had a docs-only deprecation notice since the first version of the docs in this repo. Nowadays we call things “soft deprecated” if there's just a note in the docs.
The deprecated directive needs a version, I went with the first one that had the notice (2.0; it's not in 1.6):
- https://docs.python.org/release/2.0/api/memoryInterface.html
- https://docs.python.org/release/1.6/api/memoryInterface.html
Since PEP 445, they are now direct aliases; there are no (additional) binary compatibility concerns over the preferred names.

In particular, specify equal indents and that the resulting indent equals original indent.

[3.14] gh-143054: Disallow non-top-level Cut for now (GH-143622) (GH-143790)
The behaviour of Cut in nested parentheses, Repeat, Opt, and similar
is somewhat chaotic. Apparently even the academic papers on PEG aren't
as clear as they could be.
And it doesn't really matter. Python only uses top-level cuts.
When that changes, we can clarify as much as necessary (and even
change the implementation to make sense for what we'll need).
Document that this is deliberately unspecified, and add a test to
make sure any decision is deliberate, tested and documented.
