Without the ability to set required capabilities, the REPL cannot
function properly (syntax highlighting and multiline editing can't
work).
We refuse to work in this degraded state.

gh-131189: Fix "msvcrt" import warning on Linux when "_ctypes" is not available. (GH-131201)
Fix "msvcrt" import warning on Linux when "_ctypes" is not available.
On Linux, compiling without "libffi" causes a
"No module named 'msvcrt'" warning when launching PyREPL.

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.

gh-128388: pyrepl on Windows: add meta and ctrl+arrow keybindings (GH-128389)
Fix `Lib/_pyrepl/windows_console.py` to support more keybindings, like the
`Ctrl`+`←` and `Ctrl`+`→` word-skipping keybindings and those with meta (i.e. Alt),
e.g. to `kill-word` or `backward-kill-word`.
Specifics: if Ctrl is pressed, emit "ctrl left" and "ctrl right" instead of just "left" or
"right," and if Meta/Alt is pressed, emit the special key code for meta before
emitting the other key that was pressed.

Support the "pager" binary in _pyrepl (GH-122878)
Debian (and derivatives) provide a /usr/bin/pager binary, managed by the
alternatives system, that always points to an available pager utility.
Allow _pyrepl to use it, to follow system policy.
This is a very trivial change, from a patch that Debian has been
carrying since 2.7 era. Seems appropriate to upstream.

This switches the main pyrepl event loop to always be non-blocking so that it
can listen to incoming interruptions from other threads.
This also resolves invalid display of exceptions from other threads
(gh-123178).
This also fixes freezes with pasting and an active input hook.

gh-123177: Fix prompt for wrapped lines in pyrepl (GH-123324)
When display lines above the cursor come from the cache, the first line
to not come from the cache may be a wrapped line, starting half way
through a logical line in the buffer. Detect and handle this case to
avoid accidentally drawing a stray prompt in the middle of a logical
line.
