Improvements:
1. Include the number of valid data characters in the error message.
2. Mention "number of data characters" rather than "length".

generated by Argument Clinic.  Patch by Petr Viktorin.

Rewrite the code to handle the output buffer.

Fix usage of _PyBytesWriter API. Use the new _PyBytesWriter_Resize() function
instead of _PyBytesWriter_Prepare().

This API avoids a final call to _PyBytes_Resize() for output smaller than 512
bytes.

Small optimization: disable overallocation in binascii.rledecode_hqx() for the
last write.

base64.b64encode() uses it to avoid a memory copy.

and hexlify functions.  issue9951.

0-0xffff for empty data.

Patch by Vajrasky Kok.

annotate text signatures in docstrings, resulting in fewer false
positives.  "self" parameters are also explicitly marked, allowing
inspect.Signature() to authoritatively detect (and skip) said parameters.

Issue #20326: Argument Clinic now generates separate checksums for the
input and output sections of the block, allowing external tools to verify
that the input has not changed (and thus the output is not out-of-date).

a2b_qp() now accepts keyword arguments.
All "ascii" parameters is renamed to "data" for consistancy with a2b_qp().

Initial patch by Vajrasky Kok.

_PyBytes_Resize(&v, new_size) sets v to NULL on error, so v cannot be used
anymore. Replace "Py_DECREF(v); v = NULL;" with "Py_CLEAR(v);".

I've left a couple of them in: zlib (third-party lib), getaddrinfo.c
(doesn't include Python.h, and probably obsolete), _sre.c (legitimate
use for the re.LOCALE flag).

(except in the strop module, which is deprecated anyway)
