[issue47152] Reorganize the re module sources

[STINNER Victor]

STINNER Victor <vstinner at python.org> added the comment:

It's funny to still see mentions of "experimental stuff" in Python 3.11 (2022), whereas these "experimental stuff" are there for 20 years.

*Maybe* it's time to consider that re.template() and re.Scanner are no longer experimental? Maybe change their status to alpha or beta? :-D

    - changed max repeat value in engine (to match earlier array fix)
    
    - added experimental "which part matched?" mechanism to sre; see
      http://hem.passagen.se/eff/2000_07_01_bot-archive.htm#416954
      or python-dev for details.


+# experimental stuff (see python-dev discussions for details)

+class Scanner:
