bpo-44439: BZ2File.write() / LZMAFile.write() handle buffer protocol correctly (GH-26764) 
No longer use len() to get the length of the input data. For some buffer protocol objects,
the length obtained by using len() is wrong.

bpo-43785: Improve BZ2File performance by removing RLock (GH-25299) 
Remove `RLock` from `BZ2File`. It makes `BZ2File` to thread unsafe, but
gzip and lzma don't use it too.

bpo-43510: Implement PEP 597 opt-in EncodingWarning. (GH-19481) 
See [PEP 597](https://www.python.org/dev/peps/pep-0597/).

* Add `-X warn_default_encoding` and `PYTHONWARNDEFAULTENCODING`.
* Add EncodingWarning
* Add io.text_encoding()
* open(), TextIOWrapper() emits EncodingWarning when encoding is omitted and warn_default_encoding is enabled.
* _pyio.TextIOWrapper() uses UTF-8 as fallback default encoding used when failed to import locale module. (used during building Python)
* bz2, configparser, gzip, lzma, pathlib, tempfile modules use io.text_encoding().
* What's new entry

bpo-39357: Remove buffering parameter of bz2.BZ2File (GH-18028) 
Remove the buffering parameter of bz2.BZ2File. Since Python 3.0, it
was ignored and using it was emitting a DeprecationWarning. Pass an
open file object to control how the file is opened.

The compresslevel parameter becomes keyword-only.

2dbc6e6bce Issue #23529: Limit the size of decompressed data when reading from 
GzipFile, BZ2File or LZMAFile.  This defeats denial of service attacks
using compressed bombs (i.e. compressed payloads which decompress to a huge
size).
