Change class and module objects to lazy-create empty annotations dicts on demand. The annotations dicts are stored in the object's `__dict__` for backwards compatibility.
Accessing the following attributes will now fire PEP 578 style audit hooks as ("object.__getattr__", obj, name):
* PyTracebackObject: tb_frame
* PyFrameObject: f_code
* PyGenObject: gi_code, gi_frame
* PyCoroObject: cr_code, cr_frame
* PyAsyncGenObject: ag_code, ag_frame
Add an AUDIT_READ attribute flag aliased to READ_RESTRICTED.
Update obsolete flag documentation.
Links for 'raise Exception from x' target to 'The raise statement' (7.8) section instead of 'The import statement' (7.11) section.
There are more modified links than in the bug report because I searched some other ones which can get the same improvement.
* Add length parameter to PyLineTable_InitAddressRange and doen't use sentinel values at end of table. Makes the line number table more robust.
* Update PyCodeAddressRange to match PEP 626.
* Add also references to --with-trace-refs option.
* Move _ob_next and _ob_prev at the end, since they don't exist by
default and are related to debug.
Introduce Py_TPFLAGS_IMMUTABLETYPE flag for immutable type objects, and
modify PyType_Ready() to set it for static types.

Add new C-API functions to control the state of the garbage collector:
PyGC_Enable(), PyGC_Disable(), PyGC_IsEnabled(),
corresponding to the functions in the gc module.

Removes the `list` call in the Popen `repr`.
Current implementation:
For cmd = `python --version`, with `shell=True`.
```bash
<Popen: returncode: None args: ['p', 'y', 't', 'h', 'o', 'n', ' ', '-', '-',...>
```
For `shell=False` and args=`['python', '--version']`, the output is correct:
```bash
<Popen: returncode: None args: ['python', '--version']>
```
With the new changes the `repr` yields:
For cmd = `python --version`, with `shell=True`:
```bash
<Popen: returncode: None args: 'python --version'>
```
For `shell=False` and args=`['python', '--version']`, the output:
```bash
<Popen: returncode: None args: ['python', '--version']>
```

Faster bz2/lzma/zlib via new output buffering.
Also adds .readall() function to _compression.DecompressReader class
to take best advantage of this in the consume-all-output at once scenario.
Often a 5-20% speedup in common scenarios due to less data copying.

* Add signal_state_t structure and signal_global_state variable.
* Add a module state to the _signal module.
* Move and rename variables:
* DefaultHandler becomes state->default_handler
* IgnoreHandler becomes state->ignore_handler
* sigint_event becomes state->sigint_event
* ItimerError becomes modstate->itimer_error
* Rename SetHandler() to set_handler() to be consistent with
get_handler().
Importing the _signal module in a subinterpreter has no longer side
effects.
signal_module_exec() no longer modifies Handlers and no longer attempts
to set SIGINT signal handler in subinterpreters.
In 3.12 ``True`` or ``False`` will be returned for all containment checks,
with ``True`` being returned if the value is either a member of that enum
or one of its members' value.
