* 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
Discovered using clang's MemorySanitizer when it ran python3's
test_fstring test_misformed_unicode_character_name.

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.
Rename our new MEMORY_SANITIZER define to _Py_MEMORY_SANITIZER.

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.

Adds configure flags for msan and ubsan builds to make it easier to enable.
These also encode the detail that address sanitizer and memory sanitizer
should disable pymalloc.
Define MEMORY_SANITIZER when appropriate at build time and adds workarounds
to existing code to mark things as initialized where the sanitizer is otherwise unable to
determine that. This lets our build succeed under the memory sanitizer. not all tests
pass without sanitizer failures yet but we're in pretty good shape after this.

* universal_newlines defaulting to False would suggest, that not
specifying universal_newlines explicitly and setting text to True
should cause an error, which is not the case.
* The run function didn't have the universal_newlines parameter
documented
* The check_output function didn't have its text parameter documented

The documentation was not covering multiple targets enclosed by
parenthesis nor multiple targets enclosed by brackets, adding them all
would be heavy, an else cover them all and is lighter to read.

This function may access memory which is mapped but is considered
free by libc allocator. It behaves so by design, therefore we
need to suppress sanitizer reports.
GCC doesn't support MSan, so disable only TSan for it.

1) Convert weird field name "typ" to the more standard "type".
2) For the NUMBER type, convert the value to an int() or float().
3) Simplify ``group(kind)`` to the shorter and faster ``group()`` call.
4) Simplify logic go a single if-elif chain to make this easier to extend.
5) Reorder the tests to match the order the tokens are specified.
This isn't necessary for correctness but does make the example
easier to follow.
6) Move the "column" calculation before the if-elif chain so that
users have the option of using this value in error messages.

on implicit conversion to unsigned char, but it trips UBSan

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.
