[New-bugs-announce] [issue26526] In parsemodule.c, replace over 2KLOC of hand-crafted validation code, with a DFA

[A. Skrobov]

New submission from A. Skrobov:

Updating Modules/parsermodule.c for every change in grammar and/or parser is a maintenance burden, listed as such at https://docs.python.org/devguide/grammar.html

The attached patch lets the validation code use the auto-generated DFA structures, thus ensuring it stays up to date with the grammar. It also trims the code by over 2KLOC.
