1. bpo-41690: Use a loop to collect args in the parser instead of recurs…

   …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 }] {
           [...] }

4. bpo-41675: Modernize siginterrupt calls (GH-22028)

   siginterrupt is deprecated:
   
   ./Modules/signalmodule.c:667:5: warning: ‘siginterrupt’ is deprecated: Use sigaction with SA_RESTART instead [-Wdeprecated-declarations]
     667 |     if (siginterrupt(signalnum, flag)<0) {
