* Split exit paths into exceptional and non-exceptional.
* Move exit tracing code to individual bytecodes.
* Wrap all trace entry and exit events in macros to make them clearer and easier to enhance.
* Move return sequence into RETURN_VALUE, YIELD_VALUE and YIELD_FROM. Distinguish between normal trace events and dtrace events.
The following internal macros can not longer be used as l-value:
* asdl_seq_GET()
* asdl_seq_GET_UNTYPED()
* asdl_seq_LEN()
They are modified to use the _Py_RVALUE() macro.
Add a new _Py_RVALUE() macro to prevent using an expression as an
l-value.
Replace a "(void)" cast with the _Py_RVALUE() macro in the following
macros:
* PyCell_SET()
* PyList_SET_ITEM()
* PyTuple_SET_ITEM()
* _PyGCHead_SET_FINALIZED()
* _PyGCHead_SET_NEXT()
* asdl_seq_SET()
* asdl_seq_SET_UNTYPED()
Add also parentheses around macro arguments in PyCell_SET() and
PyTuple_SET_ITEM() macros.
* Inlined code from variance functions
* Added helper functions for the float square root of a fraction
* Call helper functions
* Add blurb
* Fix over-specified test
* Add a test for the _sqrt_frac() helper function
* Increase the tested range
* Add type hints to the internal function.
* Fix test for correct rounding
* Simplify ⌊√(n/m)⌋ calculation

* Add comment and beef-up tests
* Test for zero denominator
* Add algorithmic references
* Add test for the _isqrt_frac_rto() helper function.
* Compute the 109 instead of hard-wiring it
* Stronger test for _isqrt_frac_rto()
* Bigger range
* Bigger range
* Replace float() call with int/int division to be parallel with the other code path.
* Factor out division. Update proof link. Remove internal type declaration

The presence of frozen module headers in srcdir interfers with OOT
build. Make considers headers in srcdir up to date, but later builds do
not use VPATH to locate files. make clean now removes the headers, too.
Also remove stale ``_bootstrap_python`` from .gitignore.
``Modules/Setup.stdlib`` contains ``Setup`` lines for all stdlib extension modules for which ``configure`` has detected their dependencies. The file is not used yet and still under development. To use the file, do ``ln -sfr Modules/Setup.stdlib Modules/Setup.local``.
This does two changes that are quite related.
0. it add that variable binding can occur in pattern matching, an update of 3.10
which seems to have been omitted from the list of bindings
1. Given how long the sentence already was, with even subcases in the middle of
the sentence, the commit breaks the sentence into an actual list.
