Fix stdatomic.h header check for ICC compiler: the ICC implementation
lacks atomic_uintptr_t type which is needed by Python.
Test:
* atomic_int and atomic_uintptr_t types
* atomic_load_explicit() and atomic_store_explicit()
* memory_order_relaxed and memory_order_seq_cst constants
But don't test ATOMIC_VAR_INIT(): it's not used in Python.

* bpo-27657: Fix urlparse() with numeric paths
Revert parsing decision from bpo-754016 in favor of the documented
consensus in bpo-16932 of how to treat strings without a // to
designate the netloc.

Also updates the documentation to clarify the situation surrounding
the digestmod parameter that is required despite its position in the
argument list as of 3.8.0 as well as removing old python2 era
references to "binary strings".
We indavertently had this raise ValueError in 3.8.0 for the missing
arg. This is not considered an API change as no reasonable code would
be catching this missing argument error in order to handle it.

main() is now responsible to send the ANSWER, rather than
ServerProto. main() now waits until it got the HELLO before sending
the ANSWER over the new transport.
Previously, there was a race condition between main() replacing the
protocol and the protocol sending the ANSWER once it gets the HELLO.
TLSv1.3 was disabled for the test: reenable it.

* bpo-36389: _PyObject_CheckConsistency() available in release mode (GH-16612)
bpo-36389, bpo-38376: The _PyObject_CheckConsistency() function is
now also available in release mode. For example, it can be used to
debug a crash in the visit_decref() function of the GC.
Modify the following functions to also work in release mode:
* _PyDict_CheckConsistency()
* _PyObject_CheckConsistency()
* _PyType_CheckConsistency()
* _PyUnicode_CheckConsistency()
Other changes:
* _PyMem_IsPtrFreed(ptr) now also returns 1 if ptr is NULL
(equals to 0).
* _PyBytesWriter_CheckConsistency() now returns 1 and is only used
with assert().
* Reorder _PyObject_Dump() to write safe fields first, and only
attempt to render repr() at the end.
(cherry picked from commit 6876257eaa)
* bpo-36389: Fix _PyBytesWriter in release mode (GH-16624)
Fix _PyBytesWriter API when Python is built in release mode with
assertions.
(cherry picked from commit 60ec6efd96)
* bpo-38070: Enhance visit_decref() debug trace (GH-16631)
subtract_refs() now pass the parent object to visit_decref() which
pass it to _PyObject_ASSERT(). So if the "is freed" assertion fails,
the parent is used in debug trace, rather than the freed object. The
parent object is more likely to contain useful information. Freed
objects cannot be inspected are are displayed as "<object at xxx is
freed>" with no other detail.
(cherry picked from commit 4d5f94b8cd)
* Fix also a typo in PYMEM_DEADBYTE macro comment
* bpo-36389: Add newline to _PyObject_AssertFailed() (GH-16629)
Add a newline between the verbose object dump and the Py_FatalError()
logs for readability.
(cherry picked from commit 7775349895)
* [3.8] bpo-38456: Use /bin/true in test_subprocess (GH-16736)
Instead of sys.executable, "-c", "pass" or "import sys; sys.exit(0)"
use /bin/true when it is available. On a reasonable machine this
shaves up to two seconds wall time off the otherwise ~40sec execution
on a --with-pydebug build. It should be more notable on many
buildbots or overloaded slower I/O systems (CI, etc)..
(cherry picked from commit 67b93f80c7)
* Handle when there is no 'true' command
