* The _PySys_EndInit() function now copies the
config->module_search_path list, so config is longer modified when
sys.path is updated.
* config->warnoptions list and config->xoptions dict are also copied
* test_embed: InitConfigTests now also tests
main_config['module_search_path']
* Fix _Py_InitializeMainInterpreter(): don't use config->warnoptions
but sys.warnoptions to decide if the warnings module should
be imported at startup.

test_embed.InitConfigTests tests more configuration variables.
Changes:
* InitConfigTests tests more core configuration variables:
* base_exec_prefix
* base_prefix
* exec_prefix
* home
* module_search_path_env
* prefix
* "_testembed init_from_config" tests more variables:
* argv
* warnoptions
* xoptions
* Py_HasFileSystemDefaultEncoding value is no longer tested since it
depends on the LC_CTYPE locale and the platform.
* InitConfigTests: add check_global_config(), check_core_config() and
check_main_config() subfunctions to cleanup the code. Move also
constants at the class level (ex: COPY_MAIN_CONFIG).
* Use more macros in _PyCoreConfig_AsDict() and
_PyMainInterpreterConfig_AsDict() to reduce code duplication.
* Other minor cleanups.
(cherry picked from commit 01de89cb59)
* Add C functions:
* _Py_GetGlobalVariablesAsDict()
* _PyCoreConfig_AsDict()
* _PyMainInterpreterConfig_AsDict()
* Add new _testcapi methods:
* get_global_config()
* get_core_config()
* get_main_config()
* test.pythoninfo: get global, core and main configuration
* _testembed now serializes global, core and main configurations
using JSON to reuse _Py_GetGlobalVariablesAsDict(),
_PyCoreConfig_AsDict() and _PyMainInterpreterConfig_AsDict(),
rather than duplicating code.
* test_embed.InitConfigTests now test much more configuration
variables
If tracemalloc is not tracing Python memory allocations,
_PyMem_DumpTraceback() now suggests to enable tracemalloc
to get the traceback where the memory block has been allocated.
Some FreeBSD buildbots fail to run this test as the eof was not being received by the server if the size is not big enough. This behaviour only appears if the client is using TLS1.3.

Fix an off by one error in the peephole optimizer when checking for unreachable code beyond a return.
Do a bounds check within find_op so it can return before going past the end as a safety measure.

introduced this off by one error while fixing another one nearby.
This bug was shipped in all Python 3.6 and 3.7 releases.
The included unittest won't fail unless you do a clang msan build.

Handle Unicode contents on localised Windows systems when activating a
venv. activate.bat currently breaks on German Windows systems, as chcp.com does
not return a plain number as on English systems, but (arbitrarily) appends a dot at the end
(for example "Aktive Codepage: 850." instead of "Active Codepage: 850"). The
dependency to chcp.com is removed and ctypes is used to get, set and restore the
console output code page. The code page for console input is not changed.
We can't use __VENV_PYTHON__ to find python.exe, since it's UTF-8. cmd.exe decodes
the script using the console output code page.

The test depended on '/usr/share/zoneinfo/posixrules' or equivalent
because it set TZ without explicit DST transition rules. At least
on OpenSUSE Tumbleweed that file is linked to '/etc/localtime',
making the test fail with certain local timezones,
such as 'Europe/Moscow' which doesn't have DST transitions since 2011.

Two kind of mistakes:
1. Missed space. After concatenating there is no space between words.
2. Missed comma. Causes unintentional concatenating in a list of strings.

After commit d0f49d2f50, the output of the
test suite is always buffered as the test output needs to be included in
the JUnit file in same cases (as when a test fails). This has the
consequence that printing or using debuggers (like pdb) in the test
suite does not result in a good user experience anymore.
This commit modifies the test suite runner so it only captures the test
output when the JUnit file is requested to fix the regression so prints
and debuggers are usable again.

Prior to this revision, after the shutdown of a `BaseServer`,
the server accepted a last single request
if it was sent between the server socket polling
and the polling timeout.
This can be problematic for instance for a server restart
for which you do not want to interrupt the service,
by not closing the listening socket during the restart.
One request failed because of this behavior.
Note that only one request failed,
following requests were not accepted, as expected.

Fix the documentation of copy2, as it does not copy file ownership (user and
group), only mode, mtime, atime and flags.
The original text was confusing to developers as it suggested that this
command is the same as 'cp -p', but according to cp(1), '-p' copies file
ownership as well.
Clarify which metadata is copied by shutil.copystat in its docstring.

* Use _PyUnicode_Copy in sanitize_isoformat_str
* Use repr in fromisoformat error message
This reverses commit 67b74a98b2 per Serhiy Storchaka's suggestion:
I suggested to use %R in the error message because including the raw
string can be confusing in the case of empty string, or string
containing trailing whitespaces, invisible or unprintable characters.
We agree that it is better to change both the C and pure Python versions
to use repr.
* Retain non-sanitized dtstr for error printing
This does not create an extra string, it just holds on to a reference to
the original input string for purposes of creating the error message.
* PEP 7 fixes to from_isoformat
* Separate handling of Unicode and other errors
In the initial implementation, errors other than encoding errors would
both raise an error indicating an invalid format, which would not be
true for errors like MemoryError.
* Drop needs_decref from _sanitize_isoformat_str
Instead _sanitize_isoformat_str returns a new reference, even to the
original string.

path_error() uses GetLastError() on Windows, but some os functions
are implemented via CRT APIs which report errors via errno.
This may result in raising OSError with invalid error code (such
as zero).
Introduce posix_path_error() function and use it where appropriate.
