* Remove commented deprecation of ctypes.c_buffer.
* Remove references to ctypes.c_string which doesn't exist.
* Remove StringTestCase: it only had skipped test methods.
This sentinel value (`MISSING`) is also used as default value for the `kw_only` parameter introduced in Python 3.10. It's cleaner to simply omit the usage here.

open(), io.open(), codecs.open() and fileinput.FileInput no longer
accept "U" ("universal newline") in the file mode. This flag was
deprecated since Python 3.3.
The binhex module, deprecated in Python 3.9, is now removed. The
following binascii functions, deprecated in Python 3.9, are now also
removed:
* a2b_hqx(), b2a_hqx();
* rlecode_hqx(), rledecode_hqx().
The binascii.crc_hqx() function remains available.
libregrtest now clears the type cache later to reduce the risk of
false alarm when checking for reference leaks. Previously, the type
cache was cleared too early and libregrtest raised a false alarm
about reference leaks under very specific conditions.
Move also support.gc_collect() outside clear/cleanup functions to
make the garbage collection more explicit.

Fix indentation of <no Python frame> message in a faulthandler
traceback or a Fatal Python error traceback. Example:
Current thread 0x00007f03896fb740 (most recent call first):
Garbage-collecting
<no Python frame>
- acquire the GIL at the very start[1]
- release the GIL at the very end
[1] The trace callback performs a sanity check before acquiring the GIL

Frozen modules must be added to several files in order to work properly. Before this change this had to be done manually. Here we add a tool to generate the relevant lines in those files instead. This helps us avoid mistakes and omissions.

* Functions registered with addModuleCleanup() were not called unless
the user defines tearDownModule() in their test module.
* Functions registered with addClassCleanup() were not called if
tearDownClass is set to None.
* Buffering in TestResult did not work with functions registered
with addClassCleanup() and addModuleCleanup().
* Errors in functions registered with addClassCleanup() and
addModuleCleanup() were not handled correctly in buffered and
debug modes.
* Errors in setUpModule() and functions registered with
addModuleCleanup() were reported in wrong order.
* And several lesser bugs.
Previously it returned None if the test class or method was
decorated with a skipping decorator.

Previously, when built on older macOS systems, `find_library` was not able to find macOS system libraries when running on Big Sur due to changes in how system libraries are stored.
Update the vendored copy of libexpat to 2.4.1 (from 2.2.8) to get the
fix for the CVE-2013-0340 "Billion Laughs" vulnerability. This copy
is most used on Windows and macOS.

PyPy and potentially other implementations have different or no
contraints on the number of blocks that can be statically nested. move
the test that checks for this behaviour into a unit test and mark it as
CPython-only.
Fixes:
