bpo-40421: Add pyframe.h header file (GH-19755)
Add a new separated pyframe.h header file of the PyFrame public C
API: it is included by Python.h.

Add PyFrame_GetLineNumber() to the limited C API.

Replace "struct _frame" with "PyFrameObject" in header files.
PyFrameObject is now defined as struct _frame by pyframe.h which is
included early enough in Python.h.

bpo-40334: Catch E_EOF error, when the tokenizer returns ERRORTOKEN (GH-19743)
An E_EOF error was only being caught after the parser exited before this commit. There are some cases though, where the tokenizer returns ERRORTOKEN *and* has set an E_EOF error (like when EOF directly follows a line continuation character) which weren't correctly handled before.

bpo-39995: Split test_concurrent_futures.test_crash() into sub-tests (GH-19739)
Now only test_error_during_result_unpickle_in_result_handler()
captures and ignores sys.stderr in the test process.

Tools like test.bisect_cmd don't support subTest() but only
work with the granularity of one method.

Remove unused ExecutorDeadlockTest._sleep_id() method.

bpo-38387: Formally document PyDoc_STRVAR and PyDoc_STR macros (GH-16607)
Adds a short description of `PyDoc_STRVAR` and `PyDoc_STR` to "Useful macros" section of C-API docs.

Currently, there is [one lone mention](https://docs.python.org/3/c-api/module.html?highlight=pydoc_strvar#c.PyModuleDef) in the C-API reference, despite the fact that `PyDoc_STRVAR` is ubiquitous to `Modules/`.

Additionally, this properly uses `c:macro` within `Doc/c-api/module.rst` to link.

closes bpo-40385: Remove Tools/scripts/checkpyc.py (GH-19709)
This is one of the few files that has intimate knowledge of the pyc file
format. Since it lacks tests it tends to become outdated fairly quickly.
At present it has been broken since the introduction of PEP 552.

bpo-40334: Rewrite test_c_parser to avoid memory leaks (GH-19694)
Previously every test was building an extension module and
loading it into sys.modules. The tearDown function was thus
not able to clean up correctly, resulting in memory leaks.

With this commit, every test function now builds the extension
module and runs the actual test code in a new process
(using assert_python_ok), so that sys.modules stays intact
and no memory gets leaked.

bpo-38061: subprocess uses closefrom() on FreeBSD (GH-19697)
Optimize the subprocess module on FreeBSD using closefrom().
A single close(fd) syscall is cheap, but when sysconf(_SC_OPEN_MAX)
is high, the loop calling close(fd) on each file descriptor can take
several milliseconds.

The workaround on FreeBSD to improve performance was to load and
mount the fdescfs kernel module, but this is not enabled by default.

(kevans) and Kubilay Kocak (koobs):

On FreeBSD, os.closerange(fd_low, fd_high) now calls
closefrom(fd_low) if fd_high is greater than or equal to
sysconf(_SC_OPEN_MAX).

function in a consistent state. For example, tstate->frame is now

bpo-40334: Use old compiler when compile mode is func_type (GH-19692)
This is invoked by mypy, using ast.parse(source, "<func_type>", "func_type"). Since the new grammar doesn't yet support the func_type_input start symbol we must use the old compiler in this case to prevent a crash.
