I've left a couple of them in: zlib (third-party lib), getaddrinfo.c

Report and patch by Berker Peksag.

Remove obsoleted xreadline method.

* avgpp() and maxpp() no more crash on empty and 1-samples input fragment. They now work when peak-peak values are greater INT_MAX.
* ratecv() no more crashes on empty input fragment.
* Fixed an integer overflow in ratecv().
* Fixed an integer overflow in add() and bias() for 32-bit samples.
* reverse(), lin2lin() and ratecv() no more lose precision for 32-bit samples.
* max() and rms() no more returns negative result for 32-bit sample -0x80000000.
* minmax() now returns correct max value for 32-bit sample -0x80000000.
* avg(), mul(), tomono() and tostereo() now round negative result down and can return 32-bit sample -0x80000000.
* add() now can return 32-bit sample -0x80000000.

is automatically closed.

an internal XML encoding is UTF-8 or US-ASCII.  It now accepts bytes and
strings larger than 2 GiB.

The main docs were fixed to remove mention of None long ago,
but the docstring was not.  Reported by Armin Rigo, patch

universal_newlines is true as on Windows.

skipTest() already raises an exception.

parses nested mutating sequence.

NOTE: I already backported the expat hash randomization fix in March.

Fixes issue #14340.

stream or a decoder produces data of an unexpected type (i.e. when
io.TextIOWrapper initialized with text stream or use bytes-to-bytes codec).
