It contains now the name of the parameter instead of its index when parameters
are supplied as a dict.

Partially revert commit 71d1bd9:
don't use multi-phase initialization (PEP 489) for the _signal
extension module.

Currently, empty sequences in gather rules make the conditional for
gather rules fail as empty sequences evaluate as "False". We need to
explicitly check for "None" (the failure condition) to avoid false
negatives.

The PSF board approved this use.

Simply closing the event loop isn't enough to avoid warnings. If we
don't also shut down the event loop's default executor, it sometimes
logs a "dangling thread" warning.

…ion (GH-22053)

This program can segfault the parser by stack overflow:

```
import ast

code = "f(" + ",".join(['a' for _ in range(100000)]) + ")"
print("Ready!")
ast.parse(code)
```

the reason is that the rule for arguments has a simple recursion when collecting args:

args[expr_ty]:
    [...]
    | a=named_expression b=[',' c=args { c }] {
        [...] }
