bpo-42923: Dump extension modules on fatal error (GH-24207)
The Py_FatalError() function and the faulthandler module now dump the
list of extension modules on a fatal error.

Add _Py_DumpExtensionModules() and _PyModule_IsExtension() internal
functions.

bpo-42827: Fix crash on SyntaxError in multiline expressions (GH-24140)
When trying to extract the error line for the error message there
are two distinct cases:

1. The input comes from a file, which means that we can extract the
   error line by using `PyErr_ProgramTextObject` and which we already
   do.
2. The input does not come from a file, at which point we need to get
   the source code from the tokenizer:
   * If the tokenizer's current line number is the same with the line
     of the error, we get the line from `tok->buf` and we're ready.
   * Else, we can extract the error line from the source code in the
     following two ways:
     * If the input comes from a string we have all the input
       in `tok->str` and we can extract the error line from it.
     * If the input comes from stdin, i.e. the interactive prompt, we
       do not have access to the previous line. That's why a new
       field `tok->stdin_content` is added which holds the whole input for the
       current (multiline) statement or expression. We can then extract the
       error line from `tok->stdin_content` like we do in the string case above.

bpo-42901: [Enum] move member creation to `__set_name__` (GH-24196)
`type.__new__` calls `__set_name__` and `__init_subclass__`, which means
that any work metaclasses do after calling `super().__new__()` will not
be available to those two methods.  In particular, `Enum` classes that
want to make use of `__init_subclass__` will not see any members.

Almost all customization is therefore moved to before the
`type.__new__()` call, including changing all members to a proto member
descriptor with a `__set_name__` that will do the final conversion of a
member to be an instance of the `Enum` class.

bpo-42874: Remove grep -qE options for Solaris 10 compatibility (GH-24200)
According to [bpo-42874](), some versions of grep do not support the `-q` and `-E` options. Although both options are used elsewhere in the configure script, this particular bit of validation can be achieved without them,
so there's no real harm in using a grep call with no flags.

Would be good to get some people taking advantage of the `--with-tzpath` arguments in the wild to try this out.. Local testing seems to indicate that this does the same thing, but I don't know that we have any buildbots using this option. Maybe @pablogsal?

Convert the 6 CJK codec extension modules (_codecs_cn, _codecs_hk,

multiphase initialization API (PEP 489).

Remove getmultibytecodec() local cache: always import
_multibytecodec. It should be uncommon to get a codec. For example,
this function is only called once per CJK codec module.

Fix a reference leak in register_maps() error path.
