SIGSEGV on generators in case of gi_frame.f_locals is fixed.
This applies to _FOR_ITER bytecode.
Similar checks are added to _FOR_ITER_TIER_TWO and INSTRUMENTED_FOR_ITER bytecode implementations.

The term "free variable" has unfortunately become genuinely
ambiguous over the years (presumably due to the names of
some relevant code object instance attributes).

While we can't eliminate that ambiguity at this late date, we can
at least alert people to the potential ambiguity by describing
both the formal meaning of the term and the common
alternative use as a direct synonym for "closure variable".

The function now sets temporarily the LC_CTYPE locale to the locale

different and the resulting string is non-ASCII.
This temporary change affects other threads.

- move the Py_Main documentation from the very high level API section
  to the initialization and finalization section
- make it clear that it encapsulates a full Py_Initialize/Finalize
  cycle of its own
- point out that exactly which settings will be read and applied
  correctly when Py_Main is called after a separate runtime
  initialization call is version dependent
- be explicit that Py_IsInitialized can be called prior to
  initialization
- actually test that Py_IsInitialized can be called prior to
  initialization
- flush stdout in the embedding tests that run code so it appears
  in the expected order when running with "-vv"
- make "-vv" on the subinterpreter embedding tests less spammy

Run them with different locales and different date and time.

Add the @run_with_locales() decorator to run the test with multiple
locales.

Improve the run_with_locale() context manager/decorator -- it now
catches only expected exceptions and reports the test as skipped if no
appropriate locale is available.

`isatty` returns False to indicate the file is not a TTY. The C
implementation of _io does that (`Py_RETURN_FALSE`) but I got the

Stop the world when invalidating function versions

The tier1 interpreter specializes `CALL` instructions based on the values
of certain function attributes (e.g. `__code__`, `__defaults__`). The tier1
interpreter uses function versions to verify that the attributes of a function
during execution of a specialization match those seen during specialization.
A function's version is initialized in `MAKE_FUNCTION` and is invalidated when
any of the critical function attributes are changed. The tier1 interpreter stores
the function version in the inline cache during specialization. A guard is used by
the specialized instruction to verify that the version of the function on the operand
stack matches the cached version (and therefore has all of the expected attributes).
It is assumed that once the guard passes, all attributes will remain unchanged
while executing the rest of the specialized instruction.

Stopping the world when invalidating function versions ensures that all critical
function attributes will remain unchanged after the function version guard passes
in free-threaded builds. It's important to note that this is only true if the remainder
of the specialized instruction does not enter and exit a stop-the-world point.

We will stop the world the first time any of the following function attributes
are mutated:

- defaults
- vectorcall
- kwdefaults
- closure
- code

This should happen rarely and only happens once per function, so the performance
impact on majority of code should be minimal.

Additionally, refactor the API for manipulating function versions to more clearly
match the stated semantics.

In out of tree builds, the paths can contain `../ which needs to be
resolved for the relative path calculation to work.
