Add new functions to pack and unpack C double (serialize and
deserialize):
* PyFloat_Pack2(), PyFloat_Pack4(), PyFloat_Pack8()
* PyFloat_Unpack2(), PyFloat_Unpack4(), PyFloat_Unpack8()
Document these functions and add unit tests.
Rename private functions and move them from the internal C API
to the public C API:
* _PyFloat_Pack2() => PyFloat_Pack2()
* _PyFloat_Pack4() => PyFloat_Pack4()
* _PyFloat_Pack8() => PyFloat_Pack8()
* _PyFloat_Unpack2() => PyFloat_Unpack2()
* _PyFloat_Unpack4() => PyFloat_Unpack4()
* _PyFloat_Unpack8() => PyFloat_Unpack8()
Replace the "unsigned char*" type with "char*" which is more common
and easy to use.
This adds a new standard library module, `tomllib`, for parsing TOML.
The implementation is based on Tomli (https://github.com/hukkin/tomli).
## Steps taken (converting `tomli` to `tomllib`)
- Move everything in `tomli:src/tomli` to `Lib/tomllib`. Exclude `py.typed`.
- Remove `__version__ = ...` line from `Lib/tomllib/__init__.py`
- Move everything in `tomli:tests` to `Lib/test/test_tomllib`. Exclude the following test data dirs recursively:
- `tomli:tests/data/invalid/_external/`
- `tomli:tests/data/valid/_external/`
- Create `Lib/test/test_tomllib/__main__.py`:
```python
import unittest
from . import load_tests
unittest.main()
```
- Add the following to `Lib/test/test_tomllib/__init__.py`:
```python
import os
from test.support import load_package_tests
def load_tests(*args):
return load_package_tests(os.path.dirname(__file__), *args)
```
Also change `import tomli as tomllib` to `import tomllib`.
- In `cpython/Lib/tomllib/_parser.py` replace `__fp` with `fp` and `__s` with
`s`. Add the `/` to `load` and `loads` function signatures.
- Run `make regen-stdlib-module-names`
- Create `Doc/library/tomllib.rst` and reference it in `Doc/library/fileformats.rst`
When an exception is created in a nested call to PyObject_GetAttr, any
external calls will override the context information of the
AttributeError that we have already placed in the most internal call.
This will cause the suggestions we create to nor work properly as the
attribute name and object that we will be using are the incorrect ones.
To avoid this, we need to check first if these attributes are already
set and bail out if that's the case.
Rename also struct _cframe to struct _PyCFrame.
Add a comment suggesting using public functions rather than using
directly the private _PyCFrame structure.
<stdbool.h> is the standard/modern way to define embedd/extends Python free to define bool, true and false, but there are existing applications that use slightly different redefinitions, which fail if the header is included.
It's OK to use stdbool outside the public headers, though.

Remove the HAVE_PY_SET_53BIT_PRECISION macro (moved to the internal
C API).
* Move HAVE_PY_SET_53BIT_PRECISION macro to pycore_pymath.h.
* Replace PY_NO_SHORT_FLOAT_REPR macro with _PY_SHORT_FLOAT_REPR
macro which is always defined. gcc -Wundef emits a warning when
using _PY_SHORT_FLOAT_REPR but the macro is not defined, if
pycore_pymath.h include was forgotten.
