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

annotate Python/ceval.c @ 1073:2c0432fcc270 legacy-trunk

Modified most (but not yet all) I/O to always go through sys.stdout or sys.stderr or sys.stdin, and to work with any object as long as it has a write() (respectively readline()) methods. Some functions that took a FILE* argument now take an object* argument.
