* Some handlers were wrongly described as text-encoding only, but actually they can also be used in text-decoding.
* Add more description to each handler.
* Add two REPL examples.
* Add indexes for Error Handler's name.

It is now considered a historical accident that e.g. `for` loops and the `iter()` built-in function do not require the iterators they work with to define `__iter__`, only `__next__`.
Replace sentence with confusing "pseudo-module" with two sentences
separating future statements and the __future__ module.

Enhance the documentation of the Python startup, filesystem encoding
and error handling, locale encoding. Add a new "Python UTF-8 Mode"
section.
* Add "locale encoding" and "filesystem encoding and error handler"
to the glossary
* Remove documentation from Include/cpython/initconfig.h: move it to
Doc/c-api/init_config.rst.
* Doc/c-api/init_config.rst:
* Document command line options and environment variables
* Document default values.
* Add a new "Python UTF-8 Mode" section in Doc/library/os.rst.
* Add warnings to Py_DecodeLocale() and Py_EncodeLocale() docs.
* Document how Python selects the filesystem encoding and error
handler at a single place: PyConfig.filesystem_encoding and
PyConfig.filesystem_errors.
* PyConfig: move orig_argv member at the right place.
This shows users that they can use the actual types. Using deprecated types is confusing.
This also prefers colections.abc.Sized instead of the alias typing.Sized. I guess the aliases were created to make it convenient to import all collections related types from the same place.
This should be backported to 3.9.

Sphinx 3 requires to refer to terms with the exact case.
For example, fix the Sphinx 3 warning:
Doc/library/pkgutil.rst:71: WARNING: term Loader not found in case
sensitive match.made a reference to loader instead.
* Add a glossary entry for the term "callback"
* Link to it in loop.call_soon() and in the "Concurrency and Multithreading" section

* Document `from __future__ import annotations`
* Provide plumbing and tests for `from __future__ import annotations`
* Implement unparsing the AST back to string form
This is required for PEP 563 and as such only implements a part of the
unparsing process that covers expressions.
