This adds a `feature_version` flag to `ast.parse()` (documented) and `compile()` (hidden) that allow tweaking the parser to support older versions of the grammar. In particular if `feature_version` is 5 or 6, the hacks for the `async` and `await` keyword from PEP 492 are reinstated. (For 7 or higher, these are unconditionally treated as keywords, but they are still special tokens rather than `NAME` tokens that the parser driver recognizes.)

The macros were working only because our usage happened to parse correctly.  Changing that usage (e.g. with pointers) would break the macros.  This fixes that.

d_initial, the first state of a particular DFA in the parser has always been initialized to 0 in the old pgen as well as the new pgen. As this value is not used and the first state of each DFA is assumed to be the first element in the array representing it, remove d_initial from the parser to reduce complexity.

The overflow check was relying on undefined behaviour as it was using the result of the multiplication to do the check, and once the overflow has already happened, any operation on the result is undefined behaviour.

Some extra checks that exercise code paths related to this are also added.

Don't send cookies of domain A without Domain attribute to domain B when domain A is a suffix match of domain B while using a cookiejar with `http.cookiejar.DefaultCookiePolicy` policy.  Patch by Karthikeyan Singaravelan.

…r(). (GH-12252)

* Refactor cookie path check as per RFC 6265

* Add tests for prefix match of path

* Add news entry

* Fix set_ok_path and refactor tests

* Use slice for last letter

Prevent conflicts with Linux dark themes
(and slightly darken calltip background).

test_posix.PosixUidGidTests:

* Add tests for invalid uid/gid type (str)
* Add UID_OVERFLOW and GID_OVERFLOW constants to replace (1 << 32)

Deprecated passing the following arguments as keyword arguments:

- "func" in functools.partialmethod(), weakref.finalize(),
  profile.Profile.runcall(), cProfile.Profile.runcall(),
  bdb.Bdb.runcall(), trace.Trace.runfunc() and
  curses.wrapper().
- "function" in unittest.addModuleCleanup() and
  unittest.TestCase.addCleanup().
- "fn" in the submit() method of concurrent.futures.ThreadPoolExecutor
  and concurrent.futures.ProcessPoolExecutor.
- "callback" in contextlib.ExitStack.callback(),
  contextlib.AsyncExitStack.callback() and
  contextlib.AsyncExitStack.push_async_callback().
- "c" and "typeid" in the create() method of multiprocessing.managers.Server
  and multiprocessing.managers.SharedMemoryServer.
- "obj" in weakref.finalize().

Also allowed to pass arbitrary keyword arguments (even "self" and "func")
if the above arguments are passed as positional argument.

set.add(0) and set.add.__get__(0) now raise TypeError
with same error message.

Research and fix by @bradlarsen.

I have added documentation for `PyInterpreterState_Main()`.
 I chose to place it under Advanced Debugger Support together with similar functions like `PyInterpreterState_Head()`, `PyInterpreterState_Next(`), and `PyInterpreterState_ThreadHead()` .

Semantically the same, but more idiomatic by checking against `kwargs` instead of `len(kwargs)`.

…eric IDs (GH-12565)

The error messages in the parser module are referring to numeric IDs for the nodes. To improve readability, use the node names when reporting errors.

* No need to partial read caused by EINTR for now.

Remove names from the "unimplemented interfaces" list
in the minidom docs that are actually implemented.
