With this patch, `distutils.command.install.INSTALL_SCHEMES` are loaded from
`sysconfig._INSTALL_SCHEMES`.
The distutils module is deprecated and will be removed in 3.12 (PEP 632).
This change makes the `sysconfig._INSTALL_SCHEMES` the single point of truth
for install schemes while keeping `distutils.command.install.INSTALL_SCHEMES`
exactly the same. If we, during the transition to the sysconfig, change
something, this makes sure that it also propagates to distutils until the
module gets removed.
Moreover, as discussed [on Discourse], Linux distros need to patch
distutils/sysconfig to make sure the packages will land in proper locations.
This patch makes it easier because it leaves only one location where install
schemes are defined which is much easier to patch/adjust.

The implementation is slightly different than the plan but I think it's the
easiest way how to do it and it also makes the downstream patch simple,
flexible and easy to maintain.
It's also necessary to implement this before setuptools starts bundling
the distutils module so the default install schemes stay in the standard library.
The removed code from sysconfig does not seem to have any negative effect
because, honestly, it seems that nothing actually uses the install schemes
from sysconfig at all. There were many big changes in these modules where
they were trying to include packaging in stdlib and then reverted that.
Also, the test of distutils install command does not count with the different
locations which is good evidence that the reason to have this piece of code
is no longer valid.

When printing NameError raised by the interpreter, PyErr_Display
will offer suggestions of simmilar variable names in the function that the exception
was raised from:
>>> schwarzschild_black_hole = None
>>> schwarschild_black_hole
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
NameError: name 'schwarschild_black_hole' is not defined. Did you mean: schwarzschild_black_hole?
When printing AttributeError, PyErr_Display will offer suggestions of similar
attribute names in the object that the exception was raised from:
>>> collections.namedtoplo
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
AttributeError: module 'collections' has no attribute 'namedtoplo'. Did you mean: namedtuple?
Deprecate io.OpenWrapper and _pyio.OpenWrapper: use io.open and
_pyio.open instead. Until Python 3.9, _pyio.open was not a static
method and builtins.open was set to OpenWrapper to not become a bound
method when set to a class variable. _io.open is a built-in function
whereas _pyio.open is a Python function. In Python 3.10, _pyio.open()
is now a static method, and builtins.open() is now io.open().
The new checks are only executed when one or more OpenSSL-related files are modified. The checks run a handful of networking and hashing test suites. All SSL checks are optional. This PR also introduces ccache to speed up compilation. In common cases it speeds up configure and compile time from about 90 seconds to less than 30 seconds.

* Rename functions
* Only pass type parameter to "add_xxx" functions.
* Clarify the role of the type_ready_inherit_as_structs() function.
* Move type_dict_set_doc() code to call it in type_ready_fill_dict().
* Remove redundant tracing_possible field from interpreter state.
* Move 'use_tracing' from tstate onto C stack, for fastest possible checking in dispatch logic.
* Add comments stressing the importance stack discipline when dealing with CFrames.
* Add NEWS
The suspicious check is still executed as part of the release process and release managers have been
lately fixing some actual errors that the suspicious target can find. For this reason, reactivate the suspicious
until we decide what to do in a coordinated fashion.
The configure --without-cycle-gc option has been removed in Python
2.3 by the commit cccd1e7248. It's now
time to remove the last reference to it in the documentation.
The Python _pyio.open() function becomes a static method to behave as
io.open() built-in function: don't become a bound method when stored
as a class variable. It becomes possible since static methods are now
callable in Python 3.10. Moreover, _pyio.OpenWrapper becomes a simple
alias to _pyio.open.
init_set_builtins_open() now sets builtins.open to io.open, rather
than setting it to io.OpenWrapper, since OpenWrapper is now an alias
to open in the io and _pyio modules.
The snake_case names have existed since Python 2.6, so there is
no reason to keep the old camelCase names around. One similar
method, threading.Thread.isAlive, was already removed in
Python 3.9 (bpo-37804).
Remove `RLock` from `BZ2File`. It makes `BZ2File` to thread unsafe, but
gzip and lzma don't use it too.

* Split PyType_Ready() into sub-functions.
* type_ready_mro() now checks if bases are static types earlier.
* Check tp_name earlier, in type_ready_checks().
* Add _PyType_IsReady() macro to check if a type is ready.
