bpo-1230540: Add threading.excepthook() (GH-13515)
Add a new threading.excepthook() function which handles uncaught
Thread.run() exception. It can be overridden to control how uncaught
exceptions are handled.

threading.ExceptHookArgs is not documented on purpose: it should not
be used directly.

* threading.excepthook() and threading.ExceptHookArgs.
* Add _PyErr_Display(): similar to PyErr_Display(), but accept a
  'file' parameter.
* Add _thread._excepthook(): C implementation of the exception hook
  calling _PyErr_Display().
* Add _thread._ExceptHookArgs: structseq type.
* Add threading._invoke_excepthook_wrapper() which handles the gory
  details to ensure that everything remains alive during Python
  shutdown.
* Add unit tests.

E. M. Bray c994c8fc19 bpo-21536: On Cygwin, C extensions must be linked with libpython (GH-13549)
It is also possible to link against a library or executable with a
statically linked libpython, but not both with the same DLL.  In fact
building a statically linked python is currently broken on Cygwin
for other (related) reasons.

The same problem applies to other POSIX-like layers over Windows
(MinGW, MSYS) but Python's build system does not seem to attempt
to support those platforms at the moment.

bpo-18748: _pyio.IOBase emits unraisable exception (GH-13512)
In development (-X dev) mode and in a debug build, IOBase finalizer
of the _pyio module now logs the exception if the close() method
fails. The exception is ignored silently by default in release build.

test_io: test_error_through_destructor() now uses
support.catch_unraisable_exception() rather than capturing stderr.

bpo-36721: Add --embed option to python-config (GH-13500)
To embed Python into an application, a new --embed option must be
passed to "python3-config --libs --embed" to get "-lpython3.8" (link
the application to libpython). To support both 3.8 and older, try
"python3-config --libs --embed" first and fallback to "python3-config
--libs" (without --embed) if the previous command fails.

Add a pkg-config "python-3.8-embed" module to embed Python into an
application: "pkg-config python-3.8-embed --libs" includes
"-lpython3.8".  To support both 3.8 and older, try "pkg-config
python-X.Y-embed --libs" first and fallback to "pkg-config python-X.Y
--libs" (without --embed) if the previous command fails (replace
"X.Y" with the Python version).

On the other hand, "pkg-config python3.8 --libs" no longer contains
"-lpython3.8". C extensions must not be linked to libpython (except
on Android, case handled by the script); this change is backward
incompatible on purpose.

"make install" now also installs "python-3.8-embed.pc".

bpo-36829: Add sys.unraisablehook() (GH-13187)
Add new sys.unraisablehook() function which can be overridden to
control how "unraisable exceptions" are handled. It is called when an
exception has occurred but there is no way for Python to handle it.
For example, when a destructor raises an exception or during garbage
collection (gc.collect()).

Changes:

* Add an internal UnraisableHookArgs type used to pass arguments to
  sys.unraisablehook.
* Add _PyErr_WriteUnraisableDefaultHook().
* The default hook now ignores exception on writing the traceback.
* test_sys now uses unittest.main() to automatically discover tests:
  remove test_main().
* Add _PyErr_Init().
* Fix PyErr_WriteUnraisable(): hold a strong reference to sys.stderr

* Update Modules/mathmodule.c

Co-Authored-By: Serhiy Storchaka <storchaka@gmail.com>

* Add proof sketch

* Updates from review.

* Correct and expand documentation.

* Fix bad reference handling on error; make some variables block-local; other tidying.

* Style and consistency fixes.

* Add missing error check; don't try to DECREF a NULL a

* Simplify some error returns.

* Another two test cases:

- clarify that floats are rejected even if they happen to be
  squares of small integers
- TypeError beats ValueError for a negative float

* Documentation and markup improvements; thanks Serhiy for the suggestions!

* Cleaner Misc/NEWS entry wording.

* Clean up (with one fix) to the algorithm explanation and proof.
