Using `race:` filters out warnings if the function appears anywhere in

for a function like `_PyEval_EvalFrameDefault`, which is somewhere on
the stack more often than not.

Change all free-threaded suppressions to `race_top:`, which only matches
the top frame, and add any new suppressions this exposes.

pythongh-118789: Restore hidden `_PyWeakref_ClearRef` (pythonGH-118797)

_PyWeakref_ClearRef was previously exposed in the public C-API, although
it begins with an underscore and is not documented. It's used by a few
C-API extensions. There is currently no alternative public API that can
replace its use.

_PyWeakref_ClearWeakRefsExceptCallbacks is the only thread-safe way to
use _PyWeakref_ClearRef in the free-threaded build. This exposes the C
symbol, but does not make the API public.

…no locals argument (pythonGH-119235) (python#119239)

DOCS: Suggest always calling exec with a globals argument and no locals argument (pythonGH-119235)

Many users think they want a locals argument for various reasons but they do not
understand that it makes code be treated as a class definition. They do not want
their code treated as a class definition and get surprised. The reason not
to pass locals specifically is that the following code raises a `NameError`:

```py
exec("""
def f():
    print("hi")

f()

def g():
    f()
g()
""", {}, {})
```

The reason not to leave out globals is as follows:

```py
def t():
    exec("""
def f():
    print("hi")

f()

def g():
    f()
g()
    """)
```

…ace between encoded words. (pythonGH-92281) (python#119245)

* Fix for email.generator.Generator with whitespace between encoded words.

email.generator.Generator currently does not handle whitespace between
encoded words correctly when the encoded words span multiple lines.  The
current generator will create an encoded word for each line.  If the end
of the line happens to correspond with the end real word in the
plaintext, the generator will place an unencoded space at the start of
the subsequent lines to represent the whitespace between the plaintext
words.

A compliant decoder will strip all the whitespace from between two
encoded words which leads to missing spaces in the round-tripped
output.

The fix for this is to make sure that whitespace between two encoded
words ends up inside of one or the other of the encoded words.  This
fix places the space inside of the second encoded word.

A second problem happens with continuation lines.  A continuation line that
starts with whitespace and is followed by a non-encoded word is fine because
the newline between such continuation lines is defined as condensing to
a single space character.  When the continuation line starts with whitespace
followed by an encoded word, however, the RFCs specify that the word is run
together with the encoded word on the previous line.  This is because normal
words are filded on syntactic breaks by encoded words are not.

The solution to this is to add the whitespace to the start of the encoded word
on the continuation line.

Test cases are from pythonGH-92081
