* Jumping into an "async for" loop is now disabled.
* Jumping out of an "async for" loop no longer corrupts the stack.
* Simplify the compiler.

bpo-33100: Dataclasses now handles __slots__ and default values correctly. (GH-6152) 
If the class has a member that's a MemberDescriptorType, it's not a default value, it's from that member being in __slots__.

bpo-32953: Dataclasses: frozen should not be inherited for non-dataclass derived classes (#6147) 
If a non-dataclass derives from a frozen dataclass, allow attributes to be set.
Require either all of the dataclasses in a class hierarchy to be frozen, or all non-frozen.
Store `@dataclass` parameters on the class object under `__dataclass_params__`. This is needed to detect frozen base classes.

Marcel Plch c2b0b12d1a bpo-32374: m_traverse may be called with m_state=NULL (GH-5140) 
Multi-phase initialized modules allow m_traverse to be called while the
module is still being initialized, so module authors may need to account
for that.

Miro Hrončok 5affd5c29e bpo-32885: Tools/scripts/pathfix.py: Add -n option for no backup~ (#5772) 
Creating backup files with ~ suffix can be undesirable in some environment,
such as when building RPM packages. Instead of requiring the user to remove
those files manually, option -n was added, that simply disables this feature.

-n was selected because 2to3 has the same option with this behavior.

bpo-33064: lib2to3: support trailing comma after *args and **kwargs (#6096) 
New tests also added.

I also made the comments in line with the builtin Grammar/Grammar. PEP 306 was
withdrawn, Kees Blom's railroad program has been lost to the sands of time for
at least 16 years now (I found a python-dev post from people looking for it).

Nir Soffer 4484f9dca9 bpo-33021: Release the GIL during fstat() calls (GH-6019) 
fstat may block for long time if the file descriptor is on a
non-responsive NFS server, hanging all threads. Most fstat() calls are
handled by _Py_fstat(), releasing the GIL internally, but but
_Py_fstat_noraise() does not release the GIL, and most calls release the
GIL explicitly around it.

This patch fixes last 2 calls to _Py_fstat_no_raise(), avoiding hangs
when calling:
- mmap.mmap()
- os.urandom()
- random.seed()

bpo-31804: Fix multiprocessing.Process with broken standard streams (#6079) 
In some conditions the standard streams will be None or closed in the child process (for example if using "pythonw" instead of "python" on Windows).  Avoid failing with a non-0 exit code in those conditions.

Report and initial patch by poxthegreat.
