To support virtual terminal mode in Windows PYREPL, we need a scanner
to read over the supported escaped VT sequences.

Windows REPL input was using virtual key mode, which does not support
terminal escape sequences. This patch calls `SetConsoleMode` properly
when initializing and send sequences to enable bracketed-paste modes
to support verbatim copy-and-paste.

The X/Open curses specification[0] and ncurses documentation[1]
both state that subwindows must be deleted before the main window.

Deleting the windows in the wrong order causes a double-free with
NetBSD's curses implementation.

To fix this, keep track of the original window object in the subwindow
object, and keep a reference to the original for the lifetime of
the subwindow.

[3.13] gh-133122: Fix for test_type_lookup_mro_reference. (gh-133127)

Change the unit test case to use `getattr()` so that we avoid the
bytecode specializer optimizing the access.  The specializer will call
the `__eq__` method before the unit test expects, causing it to fail.

In the 3.14 branch (gh-128164) the test is changed in a different way
to avoid the same issue.

[3.13] gh-132026: Ensure _MIPS_SIM has defined _ABI identifiers for comparison (GH-133092)

When built on a MIPS architecture, `_MIPS_SIM` is used to determine
architecture specifics. The value is expected to match either
`_ABIO32`, `_ABIN32` or `_ABI64`.

In `gcc` config/mips/mips.h these values are defined as compiler
`builtin_define` inside of a switch/case. That means, mips64el and
mips64 architectures know about `_ABI64` but don't know about `_ABIO32`
and `_ABIN32`. In turn, when CPython tries to use them in comparison,
they may be undefined identifiers.

In default compiler behavior, the undefined identifier will be
evaluated as zero, and it will not match `_MIPS_SIM`. However, the
issues pop up when `-Wundef` (or, even worse, `-Werror=undef`) compiler
flag is enabled. Then suddenly it's visible as a warning or error.
