This change gives a significant speedup, as the METH_FASTCALL calling
convention is now used. The following methods are adapted:
- str.count
- str.find
- str.index
- str.rfind
- str.rindex
On Linux >= 2.6.36 with glibc < 2.27, `getcwd()` can return a relative
pathname starting with '(unreachable)'. We detect this and fail with
ENOENT, matching new glibc behaviour.

* as_completed returns object that is both iterator and async iterator
* Existing tests adjusted to test both the old and new style
* New test to ensure iterator can be resumed
* New test to ensure async iterator yields any passed-in Futures as-is

* Extract method for _read_inner, reducing complexity and indentation by 1.
* Extract method for _raise_all and yield ParseErrors from _read_inner.
Reduces complexity by 1 and reduces touch points for handling errors in _read_inner.
* Prefer iterators to splat expansion and literal indexing.
* Extract method for _strip_comments. Reduces complexity by 7.
* Model the file lines in a class to encapsulate the comment status and cleaned value.
* Encapsulate the read state as a dataclass
* Extract _handle_continuation_line and _handle_rest methods. Reduces complexity by 8.
* Reindent
* At least for now, collect errors in the ReadState
* Check for missing section header separately.
* Extract methods for _handle_header and _handle_option. Reduces complexity by 6.
* Remove unreachable code. Reduces complexity by 4.
* Remove unreachable branch
* Handle error condition early. Reduces complexity by 1.
* Add blurb
* Move _raise_all to ParsingError, as its behavior is most closely related to the exception class and not the reader.
* Split _strip* into separate methods.
* Refactor _strip_full to compute the strip just once and use 'not any' to determine the factor.
* Replace use of 'sys.maxsize' with direct computation of the stripped value.
* Extract has_comments as a dynamic property.
* Implement clean as a cached property.
* Model comment prefixes in the RawConfigParser within a prefixes namespace.
* Use a regular expression to search for the first match.
Avoids mutating variables and tricky logic and over-computing all of the starts when only the first is relevant.
Remove extra self DECREF on ssl "no ciphers" error path.
This doesn't come up in practice because nobody links against a broken
OpenSSL library that provides nothing.

* Reads zip64 files as produced by the zipfile module
* Include tests (somewhat slow, however, because of the need to create "large" zips)
* About the same amount of strictness reading invalid zip files as zipfile has
* Still works on files with prepended data (like pex)
There are a lot more test cases at https://github.com/thatch/zipimport64/ that give me confidence that this works for real-world files.
Fixes#89739 and #77140.

Explicitly handle the case where stdout=STDOUT
as otherwise the existing error handling gets
confused and reports hard to understand errors.

Change old space bit of young objects from 0 to gcstate->visited_space.
This ensures that any object created *and* collected during cycle GC has the bit set correctly.
Python 3.10 changed from using SSL_write() and SSL_read() to SSL_write_ex() and
SSL_read_ex(), but did not update handling of the return value.
Change error handling so that the return value is not examined.
OSError (not EOF) is now returned when retval is 0.
According to *recent* man pages of all functions for which we call
PySSL_SetError, (in OpenSSL 3.0 and 1.1.1), their return value should
be used to determine whether an error happened (i.e. if PySSL_SetError
should be called), but not what kind of error happened (so,
PySSL_SetError shouldn't need retval). To get the error,
we need to use SSL_get_error.

This fixes XML unittest fallout from the https://github.com/python/cpython/issues/115398 security fix. When configured using `--with-system-expat` on systems with older pre 2.6.0 versions of libexpat, our unittests were failing.
* sax|etree: Simplify Expat version guard where simplifiable
Idea by Matěj Cepl
* sax|etree: Fix reparse deferral tests for vanilla Expat <2.6.0
This *does not fix* the case of distros with an older version of libexpat with the 2.6.0 feature backported as a security fix. (Ubuntu is a known example of this with its libexpat1 2.5.0-2ubunutu0.1 package)
Instead of calling `exec()` once for each function added to a dataclass, only call `exec()` once per dataclass. This can lead to speed improvements of up to 20%.
