bpo-32011: Revert "Issue #15480: Remove the deprecated and unused TYPE_INT64 code from marshal." (#4381)

Simplify the reverted code.

This reverts commit e9bbe8b8.

* Setting sys.tracebacklimit to 0 or less now suppresses printing tracebacks.
* Setting sys.tracebacklimit to None now causes using the default limit.
* Setting sys.tracebacklimit to an integer larger than LONG_MAX now means using
  the limit LONG_MAX rather than the default limit.
* Fixed integer overflows in the case of more than 2**31 traceback items on
  Windows.
* Fixed output errors handling.

* bpo-32015: Asyncio cycling during simultaneously socket read/write and reconnection

* Tests fix

* Tests fix

* News add

* Add new unit tests

* bpo-16055: Fixes incorrect error text for int('1', base=1000)

* bpo-16055: Address review comments

in int(), float() and complex() parsers.

This also speeds up parsing non-ASCII numbers by around 20%.

Darwin may not require libm, but it doesn't hurt to link it and simplifies configuration logic.

Access to mkfifo(), mknod() and hard link creation is controled
by SELinux on Android.
Also remove test.support.android_not_root.

It can be removed after https://github.com/python/peps/commit/c28890fb421c906241da6da718f9eacc5a3109ee

Silence only expected AttributeError.

Silence only AttributeError when get "key" and "items" attributes in
the constructor and the update() method of dict and OrderedDict .

Get rid of _PyObject_HasAttrId() and PyDict_GetItemString().
Silence only expected AttributeError, KeyError and ImportError when
get an attribute, look up in a dict or import a module.

The openfp functions of aifp, sunau, and wave had pointed to the open
function of each module since 1993 as a matter of backwards
compatibility. In the case of aifc.openfp, it was both undocumented
and untested. This change begins the formal deprecation of those
openfp functions, with their removal coming in 3.9.

This additionally adds a TODO in test_pyclbr around using aifc.openfp,
though it shouldn't be changed until removal in 3.9.

* Fix compilation of the socket module on NetBSD 8.
* Fix the assertion failure or reading arbitrary data when parse
  a AF_BLUETOOTH address on NetBSD and DragonFly BSD.
* Fix other potential errors and make the code more reliable.

* Silence error output in test_concurrent_futures (bpo-21423)
