[issue3137] Python doesn't handle SIGINT well if it arrives during interpreter startup

[STINNER Victor]

STINNER Victor <victor.stinner at haypocalc.com> added the comment:

tok_stdin_decode() clears error without check for the type. 

tokenizer_error.patch stops the tokenizer with an E_ERROR if the exception is not an UnicodeDecodeError. Fix also err_input() to support E_ERROR: leave the global exception (PyErr_*) unchanged.
