bpo-39353: Deprecate the binhex module (GH-18025) 
Deprecate binhex4 and hexbin4 standards. Deprecate the binhex module
and the following binascii functions:

* b2a_hqx(), a2b_hqx()
* rlecode_hqx(), rledecode_hqx()
* crc_hqx()

bpo-22385: Support output separators in hex methods. (#13578) 
* bpo-22385: Support output separators in hex methods.

Also in binascii.hexlify aka b2a_hex.

The underlying implementation behind all hex generation in CPython uses the
same pystrhex.c implementation.  This adds support to bytes, bytearray,
and memoryview objects.

The binascii module functions exist rather than being slated for deprecation
because they return bytes rather than requiring an intermediate step through a
str object.

This change was inspired by MicroPython which supports sep in its binascii
implementation (and does not yet support the .hex methods).

Tal Einat 1fba2ffc37 bpo-34736: improve error message for invalid length b64decode inputs (GH-9563) 
Improvements:
1. Include the number of valid data characters in the error message.
2. Mention "number of data characters" rather than "length".

Victor Stinner eaaaf136d2 Issue #25384: Use _PyBytesWriter API in binascii 
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.

Larry Hastings 581ee3618c Issue #20326: Argument Clinic now uses a simple, unique signature to 
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that the input has not changed (and thus the output is not out-of-date).

use for the re.LOCALE flag), mpdecimal (needs to build without Python.h).
