Make sure that "./python script.py" does not crash if the script
file doesn't exist.

The SAX parser no longer processes general external entities by default
to increase security. Before, the parser created network connections
to fetch remote files or loaded local files from the file system for DTD
and entities.

Fix a crash with musl libc (on Alpine Linux) when the script filename
specified on the command line doesn't exist. pymain_open_filename()
now gets the current core configuration from the interpreter state.
Modify the code to make it closer to the master branch:
* Rename _Py_CommandLineDetails to _PyCmdline
* Remove _PyMain.config: replaced with a local variable
'local_config' in pymain_init()
* Reorganize pymain_main(): move code using the "local config"
into pymain_init()
* As soon as possible, switch from the local config to the core
configuration attached to the interpreter.
Use "backslashreplace" instead of "unicode-escape". It is not
implementation depended and escapes only non-encodable characters.
Also simplify the code.

OpenSSL follows the convention that whenever you call a function, it
returns an error indicator value; and if this value is negative, then
you need to go look at the actual error code to see what happened.
Commit c6fd1c1c3a introduced a small mistake in
_ssl__SSLSocket_shutdown_impl: instead of checking whether the error
indicator was negative, it started checking whether the actual error
code was negative, and it turns out that the error codes are never
negative. So the effect was that 'unwrap()' lost the ability to raise
SSL errors.

We cannot simply call locale.getpreferredencoding() here,
as GDB might have been linked against a different version
of Python with a different encoding and coercion policy
with respect to PEP 538 and PEP 540.
Thanks to Victor Stinner for a hint on how to fix this.

A couple of fixes here to make this more PEP-8:
* Avoid multiple statements on one line with `;` statement separator -- this is very rare in Python and is "generally discouraged" in PEP 8 (and if used, per PEP 8 there shouldn't be a space before the `;`)
* Add output for the first "Formatted String Literals" example. (Side note: are the doctests for this being run? If so, why didn't it fail?)
* Avoid space before `!r`. I have generally not seen spaces before the `!`, and this also matches the style used in the docs here: https://docs.python.org/3/library/string.htmlGH-format-string-syntaxhttps://bugs.python.org/issue34712

* bpo-34589: Make _PyCoreConfig.coerce_c_locale private (GH-9371)
_PyCoreConfig:
* Rename coerce_c_locale to _coerce_c_locale
* Rename coerce_c_locale_warn to _coerce_c_locale_warn
These fields are now private (name prefixed by "_").

* bpo-34589: C locale coercion off by default (GH-9073)
Py_Initialize() and Py_Main() cannot enable the C locale coercion
(PEP 538) anymore: it is always disabled. It can now only be enabled
by the Python program ("python3).
test_embed: get_filesystem_encoding() doesn't have to set PYTHONUTF8
nor PYTHONCOERCECLOCALE, these variables are already set in the
parent.

* bpo-34589: Add -X coerce_c_locale command line option (GH-9378)
Add a new -X coerce_c_locale command line option to control C locale
coercion (PEP 538).

The test tries to fill the receiver's socket buffer and expects an
error. But the RDS protocol doesn't require that. Moreover, the Linux
implementation of RDS expects that the producer of the messages
reduces its rate, it's not the role of the receiver to trigger an
error.
The test fails on Fedora 28 by design, so remove it.
