cpython-lru_cache-weakref: Python/errors.c annotate

annotate Python/errors.c @ 46414:840064802952 legacy-trunk

Re-implement the 'warnings' module in C. This allows for usage of the 'warnings' code in places where it was previously not possible (e.g., the parser). It could also potentially lead to a speed-up in interpreter start-up if the C version of the code (_warnings) is imported over the use of the Python version in key places. Closes issue #1631171.
