gh-121220: Mark test_threaded_weak_value_dict_copy() as CPU-heavy (#121221)
Mark test_threaded_weak_value_dict_copy() and
test_threaded_weak_key_dict_copy() of test_weakref as
CPU-heavy tests

gh-120065: Increase `collect_in_thread` period to 5 ms. (#120068)
This matches the default GIL switch interval. It greatly speeds up the
free-threaded build: previously, it spent nearly all its time in
`gc.collect()`.

gh-118335: Configure Tier 2 interpreter at build time (#118339)
The code for Tier 2 is now only compiled when configured
with `--enable-experimental-jit[=yes|interpreter]`.

We drop support for `PYTHON_UOPS` and -`Xuops`,
but you can disable the interpreter or JIT
at runtime by setting `PYTHON_JIT=0`.
You can also build it without enabling it by default
using `--enable-experimental-jit=yes-off`;
enable with `PYTHON_JIT=1`.

On Windows, the `build.bat` script supports
`--experimental-jit`, `--experimental-jit-off`,
`--experimental-interpreter`.

In the C code, `_Py_JIT` is defined as before
when the JIT is enabled; the new variable
`_Py_TIER2` is defined when the JIT *or* the
interpreter is enabled. It is actually a bitmask:
1: JIT; 2: default-off; 4: interpreter.

gh-117783: Immortalize objects that use deferred reference counting (#118112)
Deferred reference counting is not fully implemented yet. As a temporary
measure, we immortalize objects that would use deferred reference
counting to avoid multi-threaded scaling bottlenecks.

This is only performed in the free-threaded build once the first
non-main thread is started. Additionally, some tests, including refleak
tests, suppress this behavior.

gh-118331: Don't raise an error if tuple allocation fails when clearing weakrefs (#118338)
It's not safe to raise an exception in `PyObject_ClearWeakRefs()` if one
is not already set, since it may be called by `_Py_Dealloc()`, which
requires that the active exception does not change.

Additionally, make sure we clear the weakrefs even when tuple allocation
fails.

gh-117657: Add TSAN suppressions for the free-threaded build (#117736)
Additionally, reduce the iterations for a few weakref tests that would
otherwise take a prohibitively long amount of time (> 1 hour) when TSAN
is enabled and the GIL is disabled.

gh-111926: Make weakrefs thread-safe in free-threaded builds (#117168)
Most mutable data is protected by a striped lock that is keyed on the
referenced object's address. The weakref's hash is protected using the
weakref's per-object lock.
 
Note that this only affects free-threaded builds. Apart from some minor
refactoring, the added code is all either gated by `ifdef`s or is a no-op
(e.g. `Py_BEGIN_CRITICAL_SECTION`).

weakref.proxy types.

Add also test_ref_repr() and test_proxy_repr().

bpo-38395: Fix ownership in weakref.proxy methods (GH-16632)
The implementation of weakref.proxy's methods call back into the Python
API using a borrowed references of the weakly referenced object
(acquired via PyWeakref_GET_OBJECT). This API call may delete the last
reference to the object (either directly or via GC), leaving a dangling
pointer, which can be subsequently dereferenced.

To fix this, claim a temporary ownership of the referenced object when
calling the appropriate method. Some functions because at the moment they
do not need to access the borrowed referent, but to protect against
future changes to these functions, ownership need to be fixed in
all potentially affected methods.

if the above arguments are passed as positional argument.
